The perbance of Eva is Amorphous Plastic, non-toxic, specific gravity of 0.95 g/cm3(lighter than water) , the products have poor surface gloss, good elasticity, soft and light weight, low mechanical strength, good fluidity and easy processing and bing. The shrinkage is larger (2%) , EVA can be used as carrier of Color masterbatch. Second, the technological characteristics of EVA EVA EVA molding processing temperature low (160-200 °C) , a wide range, its mold temperature low (20-45 °c) , the material before processing to dry (drying temperature 65 °c) . Eva Processing Mold temperature, material temperature is not easy too high, otherwise the surface is rough (not smooth) . Eva Products are easy to stick to the front die, the cold material hole of the main channel of the nozzle should be made of pull button type. Temperature over 250 °C decomposes easily. Eva should adopt "low temperature, medium pressure, medium speed" processing technology. Third, the content of VA% in the molecular chain of Eva Copolymer and the MFI of the product melt flow rate are different, the physical, chemical properties and processing properties are also different, so it can be widely used in various occasions; 1. INJECTION MOLDING: Hollow containers, vibration absorbers between rails and sleepers, soundproofing boards, fenders, floor mats, cushions for office machines, equipment, beer bottles, caps for oil drums and some plastic containers, toilet covers, sealing washer stoppers, sealing cups, bicycle seat cushions, toys, protective caps, sports balls, ski fenders, closures, protective masks, seat belts, safety helmets... etc. .
