WOOD PLASTIC COMPOSITES
WPC divides into two parts: one being solid and the other being hollow. The inner surface of the hollow structure can produce a smooth and rough inner surface with the mold technology.
According to the plastic substrate, WPC divides into PVC, PE, PP, PS, and ABS, and even products of PBT and PET are in development. Even though PVC is inflammable, it still has environmental protection issue. PE plastic wood has a large consumption; however, the oily wax texture of the material has low heat resistance, poor foaming, poor printing performance, and a product shrinkage; PP plastic wood has a wax texture and can withstand high temperature. Although the secondary processing has the risk of cracking, the appearance and texture are identical to a real wood, hence It can very well be done without post-production.
WPC products categorize into single-layered and co-extrusion. Traditional single extrusion WPC is lack of climate resilience and wear proof. Long-term outdoor exposure can cause tarnishing, crumbling, staining, mold growth, etc. However, the skin layer of a WPC co-extrusion product uses WPC recycling material or foaming to enhance climate resilience and the texture of the WPC products.
Our new generation high-level WPC extruder can produce products close to real wood grain color as well as proceeding double layered co-extrusion at the same time. The wood products are more suitable for the outdoor climate and are slip-resistant. WPC products are currently applied in assembly of summer houses, roofing tiles, stairs, tables, and chairs, etc.
