Welcome to inquire! Contact: Zhao Shuang. Plastic profile additives III: The main role of lubricant is to reduce the friction of the lubricant between the polymer and the processing equipment and between the molecules within the polymer, to prevent the degradation of the resin due to excessive heat caused by friction and improves the thermal stability efficiency of the agent. Plastic profiles additives four: processing aid processing aids primarily plastic molding process in order to improve the performance and the development of a class of improving sexual aids. Plastic profile processing temperature and decomposition temperature is relatively close to the illiquid plastic products manufacturers, easy to stick on the device coking, and therefore the production of plastic profiles require a certain amount of processing aid to overcome the shortcomings of plastic profiles itself. Plastic profiles additives Five: light stabilizers light stabilizers through shielding and absorbing ultraviolet light, the excitation energy quenching free radicals and other ways to capture photo-oxidation inhibiting polymer degradation reactions, thus giving the product a good light stabilizing effect, extend their use lifetime. Plastic profiles additives Six: filler filler is a composition and structure on different solid additives and plastics injection molding product prices, also known as filler. To improve certain physical and mechanical properties of plastic and plastic to reduce costs have a significant effect and economic value. Plastic profile production formula by adding fillers, can size plastic profiles after heating to reduce the rate of change, impact strength increases, increased rigidity injection products, while reducing production costs. Plastic profile extrusion die is a core part of the extrusion of plastic profile extrusion die technology status is directly related to the stability of extrusion, and extrusion products quality injection molding product technology, extrusion production efficiency and service life of the mold itself. Therefore, plastic profile extrusion die proper use and maintenance is very important. Plastic profile extrusion mold box to check the box to check after the arrival, the packaging is intact: Remove the packing list of technical documents, manual, etc. After unpacking, packing list by the formation of an inventory of the contents of the entire mold parts, accessories, special tools. Use more plastic profile products are: window frames, stair handrails, trunking, skirting boards, shaped like. The main raw material is hard PVC, a few are semi-rigid PVC, soft PVC, polyurethane foam and other materials low.
