Impact resistance polystyrene bai ethylene is a kind of anti – ZHI impact polystyrene by adding du plus polybutyl rubber particles into polystyrene.This polystyrene product adds micron-sized rubber particles and connects the polystyrene to the rubber particles by grafting.

When subjected to impact, the tip stress of crack propagation is released by relatively soft rubber particles.Therefore, the crack propagation is hindered and the impact resistance is improved.

Polystyrene is a brittle plastic with a wide range of USES.The computer you’re using now has a polystyrene casing.The clear plastic water cup is wrapped in styrofoam and is also made of polystyrene.

Polystyrene is a polyolefin, which is made from styrene by free radical polymerization.

A new type of polystyrene, syndiostyrene (Syndiostyrene), is available through metallocene catalytic polymerization.The two sides of the main chain interchangeably connected with the benzene rings on polystyrene, whereas the benzene rings of ordinary polystyrene are irregularly connected on both sides of the main chain.

Syndioethylene (syndiotactic agent) is a crystalline polymer with a melting point of 270 ° C.

Polybutadiene was added to the styrene polymerization system to graft the styrene onto the polybutadiene main chain.

Polystyrene and polybutadiene are incompatible, so styrene and butadiene chain segments aggregate separately, resulting in phase separation.

These polybutadiene phase regions can absorb impact energy, thus increasing the impact strength of polystyrene.
