Plastic profile additives III: The main role of lubricant is lubricant and reduce friction between the polymer molecules within the polymer processing equipment and between, prevents degradation of the resin due to excessive heat caused by friction and improves the thermal stability efficiency of the agent. Plastics Additives four profiles: processing aid processing aids primarily in order to improve the performance of plastics molding and the development of a class of additives to improve. Plastic profile processing temperature and decomposition temperature is relatively close, poor mobility, 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. Plastics additives five profiles: light stabilizer light stabilizers can inhibit oxidation of the polymer degradation light plastic pvc pipe by shielding and absorbing ultraviolet light, the excitation energy capture quenching free radicals, etc., in order to give the products a good light stability plastic pvc pipe fittings, extending their life. Six plastic profiles additives: filler is a filler in the composition and structure of different solid plastics additives, also known as fillers. To improve the physical and mechanical properties of certain plastics 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 increased supply plastic pvc pipe, rigid plastic pvc pipe prices increase, while reducing production costs. PVC material is not easily flammable, high strength, resistance to climate variability and excellent geometric stability. PVC oxidant, reductant and acid has a very strong resistance. However, it can be concentrated oxidizing acids such as sulfuric acid, concentrated nitric acid corrosion and does not apply to contact with aromatic hydrocarbons, chlorinated hydrocarbons occasions. PVC melt temperature during processing is a very important process parameters, if this argument would lead to inappropriate material decomposition problem. PVC is rather poor flow characteristics, the process is very narrow range. Especially high molecular weight PVC material more difficult to process (this material is usually added to improve the flow characteristics of lubricant), it is often used are low molecular weight PVC material. PVC contraction rate is very low, typically 0.2 to 0.6%. Pvc plastic pipe, plastic pvc pipe, sea Widex Widex provided by Qingdao Rubber Material Co., Widex Qingdao Rubber Material Co., Ltd.
