Ethylene Vinyl Acetate (EVA)

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

Ethylene Vinyl Acetate (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 and 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.

  • Polyvinyl Alcohol (PVA)

    Overview Polyvinyl alcohol (PVA for short), organic compound, white flake, flocculent or powdered solid, non-toxic, tasteless, pollution-free, can be dissolved in 80--90 °C water. Slightly soluble in dimethyl sulfoxide. Its aqueous solution has good adhesion and film-forming properties; It has chemical properties such as esterification, etherification and acetalation of long-chain polyols. It is a water-soluble polymer with a wide range of uses, its performance is between plastic and rubber, and its uses can be divided into fiber and non-fiber two major uses.

  • VAE Emulsion (Vinyl acetate-ethylene copolymer emulsion)

    Overview VAE Emulsion is an abbreviation for vinyl acetate–ethylene copolymer emulsion, which is a macromolecular emulsion, copolymerized by the high pressure emulsion polymerization method, after addition of emulsifier and initiator, with the vinyl acetate and vinyl monomer as the basic raw materials. VAE Emulsion is milk white or slight yellow in appearance. Vinyl acetate–ethylene copolymer is an important product in the vinyl copolymer, generally in an emulsion state with its vinyl acetate content within a range of 70%~95%, and called as VAE Emulsion.

  • PVOH (PVC Grade)

    Overview Modified polyvinyl alcohol (PVOH) is graded according to different degrees of polymerization, hydrolysis and copolymerization monomers. The modification of PVA is mainly to use the double bonds, ester groups and the chemical activity of the hydroxyl group after alcoholization of vinyl acetate to change the side chain group or structure, and introduce other monomers to become copolymers dominated by PVA.

  • Water Soluble PVA Fiber

    Overview Water soluble PVA fiber is a kind of PVA fiber made from polyvinyl alcohol through wet spinning, heat treatment and crimping-oiling in water at normal temperature. It is good in dry heat stability, physical and mechanical properties. The remarkable characteristic is its total dissolving in water at a range of temperature. This kind of PVA fiber is mainly used in Textile industry for making the yarn and cotton.

  • PVA high strength and high modulus fiber

    Overview PVA high strength and high modulus fiber takes polyvinyl alcohol as its major raw materials. It has good prosperities such as high modulus, high strength, alkali and acid resistance, heat resistance, anti-crack, anti-infiltration and so on. High strength and high modulus PVA fiber also has good compatibility with cement and other macromolecule material and can prevent the microcrack caused by plastic shrinkage of the concrete.
