The Best High Impact Polystyrene Plastic Granules/Virgin HIPS

Polystyrene is one of the oldest industrial thermoplastic polymers, which has a wide range of applications. This bright, pure amorphous plastic has the advantages of easy processing, rigidity, dimensional stability and transparency, but its low impact strength limits its application.High impact polystyrene is a small amount of polybutadiene connected to the polystyrene matrix.

Impact resistant polystyrene is an impact resistant polystyrene product produced by adding polybutadiene rubber particles to polystyrene. The polystyrene product will add micron sized rubber particles and connect the polystyrene and rubber particles together by branching. When impacted, the stress at the tip of crack propagation will be released by relatively soft rubber particles. Therefore, the crack propagation is hindered and the impact resistance is improved.
