╒PA12 L1833╉Long term supply of EEA injection molding of automobile steering wheel and other parts, motor parts, safety equipment, cold storage tray, household goods, sports shoes etc.. 5, EEA can be hollow molding of various oils and pharmaceutical containers. 6, EEA can be coated products and laminated products, can be used as a variety of packaging materials, metal coating. 7, EEA can be used as electrical insulation materials, shrink packaging films, shrink pipes, composite films and foam plastics. Compared with EVA, POE, EAA and other polyolefin resins, EEA has more applications in food packaging, and EA content should not exceed 8% of FDA. (1) foaming shoes material. Shoe material is the main application field of EVA resin Zui in our country. In the EVA resin used in the shoe material, the content of vinyl acetate is generally between 15% and 22%. EVA blended foam products are soft, flexible and resistant to chemical corrosion, so they are widely used in the sole and interior materials of middle and high grade tourist shoes, mountaineering shoes, slippers and sandals. In addition, this material is also used in the field of sound insulation boards, gymnastic mats and sealing materials. (2) film. The main purpose of EVA film is the production of functional films. The functional films with high weatherability, anti fog and insulation performance, because polyethylene has no polarity, even adding a certain amount of antifogging agents, the antifogging properties can only be maintained for about 2 months; and adding a certain amount of EVA made of resin film, light not only has a higher rate, but also antifogging property improved ABS melt viscosity is not affected by the temperature, but the injection pressure is obvious, but the temperature is high for the thin-walled products of the mold is favorable. The decomposition temperature of ABS, the theory on 00amv 270t: above, but in the actual process of injection molding, due to time and other process conditions, resin often 2501?or?so began to change, while ABS contained in the rubber phase does not adapt to high temperature, otherwise it will affect the product performance. Plug injection machine than screw type injection machine to choose a higher temperature, for general products, the plunger type selection temperature range between 180 and 2301, while the screw type injection molding machine at 160. 220X: can be shaped. In the molding process, the general barrel temperature (rear 150 1701C, central 170, 180 "Euro:: front 180, 210C). Nozzle temperature is 170? 180C, special attention is any change section and nozzle temperature, will be reflected in the products, caused by overflow, silver, color, luster, poor weld marks obvious flaw. PBT, PC, PA, and enhanced POM in the automobile manufacturing industry is extremely competitive, PA easy to absorb water, heat resistance, resistance of PC less than PBT; take over in car use, because the water resistance of PBT is better than PA, will gradually replace PA. In the relatively high humidity, very humid circumstances, due to moisture easily lead to plastic reduction, electrical nodes prone to corrosion, often using modified PBT. At 80 and 90% relative humidity, PBT is still in use and works well. The "PBT/PC alloy in the limousine in the application of Zui widely; its heat resistance, stress cracking resistance, excellent wear resistance, chemical corrosion resistance, low temperature and high impact strength, easy processing and good finishing, mainly used in high-grade car bumpers, car and motorcycle fender panel floor, etc..
