Using natural fiber in extruding profiles is getting popular. People try to develop new properties of the finished Wood Plastic Composite (WPC), such as PP/PE resin mixing 40-80% natural fiber or PVC mixing 40-70% natural fiber then produce different kinds of profiles. 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. Based on this mass requirement, EVERPLAST MACHINERY has developed 1. segmented twin screw extruder + special single screw extruder line. 2. parallel twin screw extruder + special single screw extruder line combine tooling die head and all down stream equipments for WPC profiles production has already got very good result. We create the market for our customers come from all over the world. APPLICATION 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.
