Good compatibility, high content of vinyl acetate copolymer with high paraffin and elastomer blend easily. The blend is often used as a hot melt adhesive. And injection molding processing of asphalt blending copolymer used for high temperature rolling asphalt. Similar to EVA copolymer, but has higher thermal stability when it is squeezed, can produce more soft membrane. EMA copolymer used for disposable gloves and cable recipe ingredients.

branched polyethylene vinyl radical polymerization under high pressure and be a part of the crystalline thermoplastic. Due to the aggregation is random, so the aggregation is random, so the main chain of the polymer is made up of different length, length of side chain. Side chain branching degree of polymer mixture. The presence of these side chains, limiting the polymer crystallization ability.

high strength UHMW fibre is a newly developed material is currently in development. This fiber has been used to race sailboats, here require materials with mildew resistance and made of parts with a size for the comprehensive performance of stability and light weight. The fiber is used as a compound structure of reinforced material.

UHMWPE some properties used for very different purposes, it is used for snowmobiles gear and drum wind snow blower impeller, on these occasions, using low temperature toughness and corrosion resistance and lubricity of UHMWPE. In the mining industry, UHMW used as chute and hopper of the sliding surface, and with his excellent wear resistance and chemical resistance. A new generation of automatic unloading ore carrier, rail freight and trucks may application of UHMWPE, because of its surface is smooth, not sticky, and wear resistance. These features make it can also be used for agricultural and earth moving machinery, steel UHMW material protection.

with the increase of low reaction temperature and pressure, the melt index down. In the practice of the process, the addition of a small amount of chain transfer agent helps to control the molecular weight. Density is determined by the degree of exercise branched, it increases with increasing pressure and decreases with temperature increase.

and polar monomers such as vinyl acetate and methyl acrylate copolymerization, can introduce additional substituent, so that we can further reduce the degree of crystallinity, improve flexibility and impact strength. Industrial applications, the different reaction conditions and comonomer type and amount of different, and the physical properties of the low density polyethylene will be changed a lot.

chemical resistance and surface smoothness can be involved in many applications. Food processing industry with UHMWPE as cut the meat, etc with the plate surface material, there needs to be non-porous surfaces. Processed food transfer machine made contact surface and UHMWPE roller, have self lubrication, the performance of the resistance to boiling water and chemical detergent. In order to prolong the service life and make the operation smooth, bottled infusion production line made of UHMWPE is often used to synchronous spiral feeder and tooth belt.

many LDPE manufacturer to adopt a strategy of LDPE plant to injection molding processing production is not easy to be LLDPE irreplaceable special copolymer. But the emphasis here is on, and their operating characteristics and homopolymerization LDPE. Copolymer belongs to nature of diversity, widely used products. Diaphragm extrusion is the main application of EVA copolymer showed superior performance: high transparency, penetration resistance, impact strength and low heat sealing temperature. These properties make EVA applied to many requirements of resin with high flexible packaging occasions. High vinyl acetate content of EVA copolymer rubber performance benefit in many ChengMo and extrusion molding in the application.

EAA or EMAA neutralization is a way of making polymer containing ionic bonding. The ion polymer matrix than their neutralizing acid copolymer has better transparency and higher melt strength. From the polymer often painted the cover with in demanding situations. Acids copolymer in strength, toughness, thermal viscosity and binding on the LDPE. Ethylene - Acrylic copolymer of two main application: one is the foam packaging, the second is as extrusion stick adhesive bonding layer between the aluminum foil and other polymers.
