Overview
EVA is a thermoplastic copolymer manufactured through the free radical polymerization of ethylene and vinyl acetate in the presence of initiating agents using the high-pressure bulk polymerization process. EVA’s properties vary dramatically from one product to another depending on the content of vinyl acetate in the macromolecule. EVAs with different properties are used for different purposes.
Applications
EVA can be processed by many different methods, such as injection molding, extrusion molding, blow molding, calendering and foaming. It is principally used in the production of packaging material, agricultural film, injection-molded products, cable material, foamed plastics, master batch carriers, blending toughening material and damping soundproof material. It can also be used in the production of hot melt adhesive, carpet backing, wax-based coatings and shoe soles. Through hollow molding, EVA can be used for making expandable hoses, micro-irrigation tubes and other types of flexible hoses.
Package, Storage & Transportation
The resin is packaged in brown paper bags and the net weight is 25Kg/bag. The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive and flammable substance is strictly prohibited.
