Polystyrene (PS for short) is a polymer synthesized from styrene monomer by free radical addition polymerization, and its chemical formula is (C8H8) N. It is a kind of colorless transparent thermoplastic, with glass conversion temperature higher than 100℃, so it is often used to make a variety of disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes.
Polystyrene is colorless and transparent, free coloring, relative density is second only to PP and PE, with excellent electrical properties, especially good high frequency characteristics, inferior to F-4, PPO. In addition, it is second only to methacrylate resin in terms of photostability, but its radiation resistance is the strongest among all plastics. The most important characteristic of polystyrene is the thermal stability and fluidity when melting is very good, so it is easy to molding processing, especially easy injection molding, suitable for mass production. Small molding shrinkage, molding product size stability is good.
High impact polystyrene is an impact resistant polystyrene product produced by adding polybutyl rubber particles in the polystyrene. The polystyrene product is made by adding micron-sized rubber particles and grafting the polystyrene to the rubber particles. When impacted, stress at the tip of crack propagation is released by relatively soft rubber particles. Therefore, the crack propagation is hindered and the impact resistance is improved.
Polystyrene is easy to process and shape, and has the advantages of transparency, low cost, rigidity, insulation, good printing and so on. It can be widely used in light industry market, daily decoration, lighting indication and packaging. In the electrical aspect is a good insulation and heat insulation material, can make all kinds of instrument shell, lampshade, optical chemical instrument parts, transparent film, capacitor dielectric layer, etc.
HIPS is high impact resistant polystyrene.
