Co-extrusion WPC profile is a high-performance wood plastic composite product produced by extrusion molding technology. Co-extrusion WPC product have both the properties and characteristics of wood and plastic, and it's a new composite materials that can replace wood and plastic for use.
In the international market, the wood plastic composite (WPC) decking is classified as “low maintenance” products, and the co-extrusion wood plastic composite (WPC) deck and PVC crust foam floor are classified as “ultra-low maintenance” products.
What's the reason?
Because the co extrusion WPC has many excellent performance, for example, better surface treatment, stronger weather resistance, high surface hardness, not easy to scratch and lower water absorption, etc. The co-extrusion technique overcomes the shortcomings of the most ordinary WPC profiles. The ordinary WPC products have f some fatal defects in longtime using such as fading, mildew and surface cracks, which lead to many complaints and returns to the WPC suppliers. By co extrusion technique, the core material is closed by co-extrusion, which can effectively solve these problems fundamentally. And It is very helpful to increased the warranty period of wood plastic composite from 15 years to 25 years.
In WPC industry, the co-extrusion WPC is called as the second-generation WPC.
At present, the main co extrusion wood plastic composite are for PE WPC, PVC WPC and ASA in the co extrusion WPC industry. Among them, co extrusion PE WPC type has a large output, the reason is that the amount of PE WPC is large, accounting for more than 75% in the market.
By now, All most all Chinese wpc factory wood like to use recycled materials for the production, so it is more necessary and urgent to adopt the co extrusion WPC technique, otherwise it will soon be eliminated by the market.
