The Questions You Want To Know About The Wood-plastic Composite

1. What is wood-plastic composite?

Wood-plastic composites are new materials which is the best alternative to natural lumber as a building material. WPC is made from wood fiber and plastic, because there is plastic in it, therefore it has a better elasticity modulus. Moreover, due to it contains wood fiber and mixed well with plastic, thus it has the same physical and mechanical properties as hardwood, such as compression resistance and bending resistance, and its durability is obviously better than natural wood materials. The surface hardness is 2-5 times higher than natural lumber.

The most widely use of WPCs are outdoor deck floors, but it is also used for railings, fences, landscaping timbers, cladding and siding and so on. In recent years, people in the flooring industry starts referring to WPC as a type of floor that has a basic structure of top polyethylene plus a rigid extruded core.

Our products comprise 30% plastic, 60% wood fiber, and 10% additives including UV stabilizers, coupling agents, lubricants etc. Compared with other WPC manufacturers in China, who use mixed wood fiber, we use hardwood fiber. While other WPC products are made with 25% to 28% plastic, our WPC products are made with 30% plastic, making our products feature exceptional strength.

2. What are the types of wood-plastic composite?

WPC is mainly divided into two categories: PE WPC and PVC WPC:

PE wood-plastic products are mainly used in outdoor garden construction, such as guardrails, floors, trash cans, flower ponds, pallets and so on. It features excellent water resistance, corrosion resistance and high hardness, and is easily deformed and buckled by heat.

Even though PVC WPC products are low cost than PE WPC, it’s not suggested to install in outdoor environments. Due to its characteristics, PVC is easy to fade and the shore hardness is worse than PE. The most important thing is that the water absorption of PVC products is up to 5% which is way higher than PE composite decking.

3. Compared with wood, what are the advantages of WPC products?

WPC products are environmentally friendly and 100% recyclable. WPC products are anti-UV, waterproof, moisture-proof, mothproof and anti-mildew, and fire resistant. WPC products have no maintenance cost, they are no need for painting and other special maintenance.

4. Will low-temperature weather affect WPC?

Wood plastic composite still performs well even in low-temperature weather. However, because plastic accounts for more than 50% of the composition of wood plastic, it will become harder to drill in extremely cold conditions. In this case, pre-drilling is required.

5. Does WPC fade?

All the WPC product will fade a little after it is exposed to the sun and undergoes the weather. The anti-UV additives are added to reduce the fading and it will be much more suitable for outdoor application. During the first 3 months, the color may fade a little with an approximated percentage of 5% to 10%, this will not affect the overall effect. After that, the color will stay at a stable level through the lifetime of the product.

6. How to store WPC products?

WPC products are much heavier than wood with the same volume. It should be placed on the flat floor for long time storage to prevent warping. We usual suggest customer to use galvanized steel pallet for WPC packing.

Advantages and Disadvantages Of WPC Flooring - WoodandBeyond

Wood Plastic Composite, commonly abbreviated as WPC, serves as the fundamental component in various indoor and outdoor flooring styles. It is frequently used in the makeup of vinyl plank flooring, a form of flooring that imitates the appearance of authentic wood. This imitation is achieved through a top layer printed with a realistic wood pattern. If you are considering WPC flooring over its closest alternatives, namely,  engineered wood flooring, laminate flooring and SPC flooring, you will do well to understand the advantages and disadvantages of WPC flooring to make an educated decision over this flooring suitability for your project.

What Are The Key Advantages of WPC Flooring

Robustness and Endurance: WPC flooring stands out for its exceptional durability and resistance to everyday wear and tear, such as scratches, dents, and scuffs. Unlike traditional wood, which is prone to warping, shrinking, and cracking, WPC maintains its structure and integrity, even under heavy foot traffic and extreme weather conditions.

Moisture Resistance: This flooring is highly resistant to water, able to endure prolonged exposure to moisture without succumbing to warping, swelling, or rotting. Its suitability for moisture-rich environments like kitchens and bathrooms makes it a practical choice for areas prone to humidity or water spills.

Eco-Friendly Composition: WPC flooring is an environmentally conscious choice, incorporating recycled wood fibres and polymers, thus reducing reliance on virgin wood. It typically contains lower levels of formaldehyde, contributing less to indoor air pollution compared to traditional wood flooring.

Low Maintenance Needs: Requiring minimal upkeep, WPC flooring is easier to maintain than natural wood. Regular sweeping and occasional damp mopping with mild soap are sufficient for cleanliness. For more thorough cleaning, specialised WPC cleaning solutions are available.

Design Versatility: With a range of colours, textures, and styles, WPC flooring mimics the natural allure of wood while offering the practical benefits of plastic composites. This versatility allows for a wide array of aesthetic preferences to be catered to.

Underfloor Heating Compatibility: Ideal for both indoor and outdoor settings, WPC flooring works well with underfloor heating systems, ensuring even heat distribution and enhanced comfort.

Flexible Installation: The installation of WPC flooring is straightforward, often involving click-together mechanisms or adhesives. This ease of installation makes it a DIY-friendly option, reducing the necessity for specialised tools or expertise.

Cost-Effectiveness: While the initial outlay for WPC flooring might be marginally higher than traditional wood, its low maintenance and longevity offer long-term financial benefits, making it a cost-effective flooring solution.

Sustainability and Environmental Impact: Utilising recycled materials, WPC flooring is a sustainable and environmentally friendly alternative to conventional wood flooring. This approach significantly lowers the demand for virgin wood, lessening environmental impact.

Safety and Stability: Typically slip-resistant, WPC flooring is a safer option for wet or high-traffic areas. Its stable and uniform structure also ensures comfort and stability, especially for barefoot or sock-wearing individuals.

What Are The Key Disadvantages of WPC Flooring

Susceptibility to Discolouration: WPC flooring, particularly lighter or natural wood finishes, may discolour over time due to sunlight exposure. This occurs as the plastic components in the composite degrade under UV radiation, leading to faded or altered colours.

Scratch Resistance Limitations: Although WPC flooring is generally scratch-resistant, it may not match the durability of solid hardwood. Deeper scratches or gouges tend to be more noticeable on WPC surfaces than on natural wood.

Heat Sensitivity: WPC flooring is not heat-resistant. Direct contact with extremely hot items, like cookware or grills, can cause the material to burn or melt. Using heat pads or trivets is advisable to prevent heat damage.

Vulnerability to Extreme Temperatures: Rapid or extreme temperature changes can cause WPC flooring to warp or crack. This is because the plastic components in the composite are more prone to expansion or contraction compared to wood fibres.

Colour and Texture Range: Despite offering various colours and textures, WPC flooring may fall short in replicating the intricate nuances and variations of natural wood. This artificial appearance can be more noticeable upon closer inspection.

Chemical Off-Gassing Concerns: Some WPC flooring products might emit volatile organic compounds (VOCs) during installation, potentially causing temporary odours or irritation. Choosing high-quality WPC products from reputable manufacturers with strict VOC standards is crucial.

Compatibility with Floor Finishes: There could be issues with certain floor finishes adhering to WPC flooring, particularly if the surface is treated with sealants or protective layers. Consulting a flooring expert is recommended for compatibility checks with specific finishes.

Noise Transmission: Compared to solid hardwood, WPC flooring may not be as effective in soundproofing. Installation methods like click-lock mechanisms or adhesives can amplify noises such as footsteps, especially noticeable with thinner WPC planks.
