〓EVA UL00514≡Long term supply of POM 1, POM application of consumption growth in the lubrication, abrasion resistance, rigidity and dimensional stability requirements more stringent sliding and rolling mechanical components, the performance is very superior, it is mainly used for industrial machinery, automobile, electronic and electrical, plumbing and irrigation supplies etc.. Chinese POM market is growing rapidly, in 2002 China POM market apparent consumption of 136 thousand and 570 tons, in 2002 1990 ~ POM to market the apparent consumption of the average annual growth rate of 11.7%. Chinese POM market is expected in 2005 apparent consumption of 168 thousand tons, in 2005 2000 ~ POM to market the apparent consumption of the average annual growth rate will reach 10.3%. PBT is easy to flame retardant and can reach UL94V-0 grade. Because of its good compatibility with flame retardants, it is easy to develop reactive or additive flame retardant grades. Flame retardant products are widely used in the electronic and electrical industries. The PBT in the high temperature and high humidity environment water and easy decomposition, use caution. Their excellent electrical properties, volume resistivity and high dielectric strength, excellent arc resistance, moisture absorption is small, in the humid and hot environment, can maintain stable performance, is the ideal material for electronic and electrical components. The easy processing and two processing, easy to use ordinary injection molding or extrusion equipment. Because the crystallization speed is fast, the fluidity is good, the mold temperature is also lower than other engineering material requirements. It only takes a few seconds to process the thin-wall parts, and the large parts only need 40-60s. ABS short for ABS. ABS is usually a pale yellow or milky granular amorphous resin. ABS is one of the widely used engineering plastics for zui. Chinese ABS a AcrylonitrileButadiene Styrene plastic plastic chemical name of acrylonitrile butadiene styrene plastic machinery, automobile, electronic application products such as electrical properties of impact resistance, heat resistance, low temperature resistance and CAS No.9003-56-9 directory main origin of molecular structure of ABS resin structure, with elastomer as the graft copolymers and the grafting titleABS copolymer resin backbone hard; or to ABS resin mixture and hard rubber elastomer. EVA vinyl content in 5%~10% EVA products for the elastic film; 3, vinyl acetate content in 20~28% EVA, mainly used for hot melt adhesives and coating products; 4, vinyl acetate content in 5%~45%, the main products for the film (including agricultural film) and sheet, injection molding, molding products, foam products, hot melt adhesive etc.. PC /ABS, the mixed material also shows excellent flow characteristics. The shrinkage rate is about 0.5%. The characteristics of PC, /ABS is a mixed through the synthesis of modified engineering plastics mixing. Among them, PC "is polycarbonate, ABS is acrylonitrile (A), butadiene (B) and styrene (S) copolymer. This modified plastic than pure PC, and better ABS performance, such as: enhance impact resistance, heat resistance, hardness and so on. SAN copolymerization process can be divided into emulsion grafting emulsion, SAN blending, emulsion grafting, suspension SAN mixing, emulsion grafting, bulk SAN mixing three, of which the latter two are more applied in industrial devices. The three emulsion graft blending processes include the following intermediate steps: the preparation of butadiene latex, the synthesis of graft polymers, the synthesis of SAN copolymers, and the treatment of blends
