Profile

Plastic profile products are used more: window frames, stair handrails, line trough, baseboard, special-shaped tubes, etc.. Raw materials are mainly hard PVC, a small number of semi hard PVC, soft PVC, polyurethane foam and other materials.
For the hard PVC plastic profiles, there are many shortcomings, such as ACR, CPE, EVA, MBS and so on, which can improve the impact strength. CPE (chlorinated polyethylene), EVA (ethylene vinyl acetate copolymer), ACR (acrylic acid), MBS (methyl methacrylate butadiene styrene graft copolymer) general addition amount 6%~10%. MBS is mainly used in transparent plastic profile products, EVA is best not to use the lead stabilizer, when the molding process is poor, but also easy to powder spot, CPE is best not to share with zinc stabilizer, and CPE low temperature is not good.
