Plastic profile products use more: window frames, stair handrails, trunking, skirting boards, shaped and so on. The main raw material is hard PVC, few are semi-rigid PVC, soft PVC, polyurethane foam and other materials low. For hard PVC plastic profiles, the existence of the shortcomings of poor impact resistance, often used to add ACR, CPE, EVA, MBS modified PVC plastic pipe and other products, in order to improve the impact strength. CPE (chlorinated polyethylene), EVA (ethylene - vinyl acetate copolymer), ACR (acrylic resin), MBS (methyl methacrylate - butadiene - styrene graft copolymer) is generally added in an amount of 6% to 10 %. MBS is mainly used for transparent plastic profile products in the supply of PVC plastic pipe, EVA PVC plastic pipe is best not to share price and lead stabilizers, when forming the common poor, but also easy to spot from the powder, CPE preferably not with zinc stabilizer share, and the CPE is not very good low temperature resistance. When the production of plastic products, PVC plastic pipe profiles, control of process conditions such as temperature, screw speed, traction speed and so on. Import PVC phase mixing in heterogeneous polymer phase - polymer melt blending is a simple and effective method for modifying and has accumulated experience in the actual production. Generally when two or more different polymers melt blended, both the nature of these polymer mixtures can be prepared. In order to improve the fluidity of rigid PVC, impact properties, etc., the most commonly used polymer blends are: acrylonitrile - butadiene - styrene (ABS), which is mainly to improve the impact strength. Methyl methacrylate - butadiene - styrene (MBS), in addition to weather resistance, the rest of the performance are nearly ideal, especially impact strength, as long as a small amount can be greatly improved. Chlorinated polyethylene (CPE) can improve the impact strength, if the added amount of 20%, the impact strength can be very high. Ethylene - vinyl acetate (EVA) can improve the impact strength.
