Teflon and PTFE are two different names of same polymer material. To put in other words, Teflon is the trade name for PTFE. The Poly tetra fluoro ethylene (PTFE) is a unique polymer with some particular properties which are hardly or never found in any other organic polymer. That’s what distinguishes it from Teflon. Do you know what those important properties are? High chemical resistivity Lowest surface energy, & High thermal stability You might have got the gesture here, what the curtain opener is telling about! Yes, we are going to throw light on the minor differences between PTFE and Teflon today. Superficially, they both are same, but there is a slight chain of differences between both creating a thin line distinguishing both polymers in terms of their applications, features, and other specifications. Let’s take a detailed insight into both. What is PTFE? The Poly tetra fluoro ethylene is a fluorocarbon solid since it possesses high-molecular-weight compound consisting of carbons and fluorine only. It can also say to be a thermoplastic polymer consisting of just two elements: fluorine and carbon. It is a hydrophobic polymer with least amount of coefficients of friction against any solid known to anyone. This unique feature lends itself well to those applications which demand low levels of resistance. What is Teflon? Teflon is a trademark of a company spin offed from DuPont called Ken Arse. We can also call it a chain of carbon atoms that are saturated with fluorine or used two carbons being saturated with hydrogen. The Teflon is one of the most sought-after engineering plastics invented 70 years ago, and still, it is highly reputed in the market for its incredible performance in dynamic areas as compared to other engineering plastics. Difference between PTFE & Teflon in terms of Features, Uses, & Applications Features / Properties of PTFE PTFE is hydrophobic – The primary feature of PTFE is, it never reacts with water being a hydrophobic polymer material. It is also non reactant with alcohol, and other highly polar oxygen and hydroxyl-containing compounds. This property is an outcome of the high electronegativity of polymer structure. High Chemical properties – Another highlighting property of PTFE polymer is, it comprise of high chemical and corrosive resistant properties. For this reason, it has been used as pipeline coating and containers in which reactive and corrosive chemicals are required. Low tensile strength – Lastly, this polymer also comprises of high wear resistance, low tensile strength, and least creep resistance. PTFE is Non- Receptive – Since PTFE is highly non-receptive. Hence, it is used for coating surface of numerous cookwares, generally known as a non-stick skillet. Bonding Structure – The holding structure of PTFE keeps the transmission of electrons through the atomic orbital of the PTFE polymer. The holding structure of PTFE is extremely steady. Teflon isn’t exceptionally responsive to compound operators in light of the strength of the fluorine to carbon bonds. Uses of PTFE Since PTFE is a non-reactive material, perhaps due to its high strength of carbon-fluorine bonds, so it is often the choice of material utilized as a part of compartments and pipework for destructive and responsive chemicals. PTFE is also used in multiple computer applications including; coaxial cables, hookup wires, and to name a few due to its exceptional dielectric properties. Additionally, it is also utilized as a lubricant to increase wear resistance as well to reduce the friction. PTFE is utilized as a non-stick covering for skillet, cookware and even modern sustenance handling apparatus. Features / Properties of Teflon Low coefficient of friction – The Coefficient of friction actually helps in measuring how easily a standard sized material block can slide down over a flat surface of a given material. Teflon is rich in this feature – low coefficient of friction – which makes this polymer best for nonstick food cooking. Good Dielectric Properties – PTFE does not discharge electrons from the polymer orbital effortlessly because of the quality bonding between of the carbon and fluorine. This influences Teflon to have great dielectric properties and makes it a perfect protector. It is Reusable – Teflon is reusable and can keep going for quite a long time and years. These adaptable sheets can likewise be utilized to secure the base warmth platen amid sublimation or whenever there might seep around your picture. Uses of Teflon Today, Teflon is used in variety of applications including substitute bones for skull, ear parts, heart valves, tendons, nose, hip, nose, knees, dentures, sutures, and facial tracheas, as a biomedical material in fake corneas, nose cones and warmth shields for space vehicles and for their fuel tanks. The Teflon sheets can also be utilized as a weight to keep a transferring paper at its place between the warming procedures to guarantee to culminate comes about. For this reason, Teflon rod suppliers put all their efforts to make this product, a multi-functional one to make it versatile for variety of industrial, as well as medical applications. To Conclude There is not such a vast difference between both Teflon and PTFE. Though one is more dominant over other due to some highlighting features which brings it into the limelight, otherwise Teflon is just a brand name of the same polymer.

READ FULLI was excited to take the opportunity to look at a bunch of paints at the same time. It’s something I’ve never done before. It forced me to think about why do I like the paint brands that I do. I unconsciously rate paint when I work with it; but it took me some time to actively figure out how I decide if I like a brand. I’m not going to pretend that I am not somewhat biased to paint brands, because I am.
I have been working to as a professional artist for way longer than I’d like to admit and with all of that time, I have my own personal experience with paint. I have used the cheapest stuff possible when I barely had two dimes to rub together as a baby art student, and as I have grown as an artist and painted significantly more I’ve gotten to know what I like in paint.
This is my personal experiment to pit 6 other brands of heavy bodied acrylic paint up against my favorite brand that I predominantly use. I am willing to have my opinion changed and I’m curious to see if I would consider brand switching. I hope in explaining at how I look at paint, maybe it will help you decide when you are searching for new paint. Please, take my opinions with a grain of salt, they are merely my thoughts based on my preferences and personal experiences as an artist.
I want to add before I begin: I have no affiliations with any paint brand or art supply company, all the paints I purchased were paid for by Visual Arts Passage. I would also like to say that the quality art supplies do not make you a great artist, but it can be nice and can possibly enhance your painting experience. One of my favorite artist’s Mark English shopped for his art supplies at the hardware store and his work are masterpieces.
Let’s begin: When I thought about this challenge of rating paint I decided to narrow the field to heavy body acrylics, because that’s what I work with. I also took advantage of that fact that when I started writing this article it was the beginning of the holiday season. There were a lot of paint sets available. This gave me the chance to look at brands primary colors as well as black and white without breaking the bank.
I started off just looking at the individual paint sets and rating them, but then also started to access the sets they put together. If you are a beginner with acrylics, a basic set of white, yellow, red, blue and black should be enough to allow you to make the colors you need. You should have nice tints, get good warms, cools, darks, lights and be able to created secondary colors (green, orange, and purple).
For this reason, I realized that making paint swatches and tinting the colors with white and black wasn’t enough for me to decide if I liked it or not, so I also did a little portrait studies. These little painting were where I was really able to decide if I liked a paint brand or not. I tested all of these paints on white gessoed cardboard (upcycling at it’s best!), and used copyright free images for references for my studies.
My at home heavy body acrylic brand of choice is Liquitex – so I am definitely skewed in that direction and it’s what I compare everything against. Because of that, I didn’t need to purchase a set but used the colors that would be in a set.
For more information, please visit bulk acrylic tubes.
This paint is a delight to work with, I got wonderful warms and cools. The set didn’t actually include black, so I made it by mixing raw umber with ultramarine blue. I would highly recommend this brand. I thought it had good pigment, mixed beautifully and also maintained good color when watered down, and didn’t darken significantly when it dried. This isn’t even their professional brand, I’m impressed, these are quality acrylics. Individual tubes can cost between $7-13.
Galeria Acrylic is a high-quality acrylic paint which delivers professional results, ideal for artists who want high quality more accessible range. The Galeria Acrylic range offers excellent brilliance, professional quality pigment, opacity and permanence with a smooth, satin finish. Galeria uses either the same pigment as the professional range or a similar pigment load, but in a lower concentration. This makes it easy to use with, or transition to artist grade paints when a wider choice and high pigment strength is needed.
I really wanted to like this brand. I have ordered supplies from this company before and always have had a positive experience, but their acrylic paint brand was disappointing for me. The Napthol Red was very cool and dried dark, when I tried mixing with yellow it continued to stay cool. I also found a slight grittiness to the paint itself, and thought it was odd how matte it dried, almost like gouache. To me this said their pigment quality is not as high as advertised. At $5-9 a tube I was hoping to tell you that this would be great, but honestly I wouldn’t recommend this brand. At best this is a student grade paint, in spite of describing itself as professional quality. I will add that I liked that their paint tubes are recyclable. $5-9 per tube.
Smooth, lightfast, and permanent, with excellent pigment quality, color strength, and longevity, Blick Artists’ Acrylics offer an exceptional combination of quality and value.
I’m familiar with the brand Holbein and have used their watercolor paint before, but I’ve never used their line of acrylic paints. I thought it was super smooth, mixed beautifully and had a nice vibrancy. I got good warms and cools. I’m a big dabber with my finger to blend and it holds up. Working with primary colors and white and black should be enough to give you the full range of color- this set does that. I did find because its’ primary colors were somewhat transparent, it was tough layering on top of a darker color. The transparency of the colors versus the opaqueness of the white and black takes a little getting used too, but overall I really like this paint and I would buy it, though it is a more expensive brand. Price per tube $9-22
Professional quality at an affordable price — that’s what you get with Holbein Heavy Body Artist Acrylics, engineered to add more luster, brilliance, and color vigor to your paintings, as well as higher lightfast ratings.
This acrylic paint was more soft body than heavy bodied in spite of it advertising itself that way. This was a Hail Mary pass, super affordable so I thought I’d give it a try. I wanted this one to be an exciting surprise- alas it’s living up to it’s price. It dries glossy, which is better than Blick and I am pleasantly surprised that I can mix a warm color. Out of the tube the red is more pinkish so I worried because of that it would be cool, but the pigment is okay. It’s pretty transparent and I found layering difficult. At best this is student grade paint. For $3-4 a tube, it’s okay.
Thick and Rich Color! By combining the finest pigments, superior binding, and modern manufacturing techniques, Soho Urban Artist Acrylics give you all the best-loved qualities of a professional acrylic color at a very affordable price point.
I have heard a lot about this acrylic paint, and I know many artists that use it. This may controversial on my part, but I wasn’t a huge fan. The yellow, red and blue are really nice separately, they are heavy bodied, have a smooth consistency, and have a good amount of pigment in the paint. I take issue with the version of primary colors they send in the set. I find it weird that they include a brilliant blue that is like a cerulean blue in the set when they included a cadmium red light. With their basic set you can’t mix a purple. If you’re going to provide a primary color set, you should be able to mix secondary colors (orange, green and purple.) In my opinion, it says an artist didn’t put this set together because primary colors, plus white and black should be enough to make all the color you need. If you want to work with a limited palette, which I think is smart for a beginner painter to learn about color, this set won’t work. Maybe this won’t bother anyone else, but this irks me. When painting faces, purple is an essential color for undertones on the face. I find that this paint company is good enough that they should have done better on this. I struggled with painting this portrait because of I couldn’t mix a purple. For an acrylic paint set at this price, I expect better. Price per tube $7-22. Overall, the paint is good, but the set should change it’s blue.
Pure pigments in the highest possible concentrations are combined with superior-quality polymer vehicles to produce colors with exceptional clarity, covering power, and tinting strength. A wide range of single pigment formulas offers excellent mixing results. Although they are professional quality
