阻燃性HIPSPH-88E奇美--聚乙烯商品会加上μm级pvc颗粒并根据芽接的方式把聚乙烯和pvc颗粒联接在一起。当受到损伤时，裂痕拓展的内应力会被相对性绵软的pvc颗粒释放出来掉，因而裂痕的扩大遭受阻拦，耐冲击性获得了提升。
聚乙烯是一种应用领域普遍的延性塑胶。你如今已经应用的计算机系统的机壳便是聚乙烯的。全透明的塑料杯子，包装袋子的塑料泡沫也是由聚乙烯做成的。聚乙烯归属于异戊橡胶，是由丁二烯根据氧自由基汇聚而成的。根据茂金属催化反应汇聚可以获得一种新式聚乙烯，即间同聚苯乙烯（syndiotactic）。间同聚乙烯上的苯环更替地联接的碳链的两边，而一般聚乙烯的苯环在无规地联接在碳链两边。间同聚乙烯（syndiotactic）是结晶体高分子材料，溶点做到270℃。在丁二烯汇聚管理体系中添加聚丁二烯，使丁二烯在聚丁二烯碳链上热聚合汇聚。聚乙烯和聚丁二烯是不兼容的，因而丁二烯和丁二烯开链各自集聚，造成相分离。这种聚丁二烯相区可以消化吸收撞击能，进而增强了聚乙烯的影响抗压强度HIPS橡胶制品奶白色不全透明颗粒物.相对密度为105g/cm^3.熔化溫度150~180℃.分解反应溫度300℃.溶解脂肪烃，钛酸异丙酯烃，吩噻嗪（除尔酮外）和脂类.可耐很多矿物质机油，有机物，碱，盐，低等醇以及溶液，不抗开水
Polystyrene products will add micron rubber particles andconnect polystyrene and rubber particles together by branching.When impacted, the tip stress of crack propagation will be releasedby relatively soft rubber particles, so the crack propagation ishindered and the impact resistance is improved.
Polystyrene is a kind of brittle plastic with a wide range ofapplications. The shell of the computer you are using now ispolystyrene. Transparent plastic water cups, plastic foam forpackaging, are also made of polystyrene. Polystyrene belongs topolyolefin, which is formed by free radical polymerization ofstyrene. A new type of polystyrene, syndiotactic, can be obtainedby metallocene catalytic polymerization. The benzene rings on thesame polystyrene are alternately connected to both sides of themain chain, while the benzene rings of ordinary polystyrene arerandomly connected to both sides of the main chain. Syndiotactic isa crystalline polymer with a melting point of 270 ℃. Polybutadienewas added into the styrene polymerization system to graft styreneonto the main chain of polybutadiene. Polystyrene and polybutadieneare incompatible, so the segments of styrene and butadieneaggregate respectively to produce phase separation. Thesepolybutadiene phase regions can absorb impact energy and improvethe impact strength of polystyrene. Hips engineering plastics aremilky opaque particles The density is 105g / cm ^ 3 Meltingtemperature 150 ~ 180 ℃ Thermal decomposition temperature 300 ℃Soluble in aromatic hydrocarbons, chlorinated hydrocarbons, ketones(except alkanone) and esters It is resistant to many mineral oils,organic acids, alkalis, salts, lower alcohols and their a, but not boiling water
