Polistirol (GPPS, HIPS) 3903190000
Polystyrene is a thermoplastic material with high hardness and good dielectric properties, chemically resistant to alkalis and acids, except for nitric and acetic acid.
Polystyrene is easily formed and colored, has low moisture absorption, high moisture resistance and frost resistance. Polystyrene products have a high gloss. General purpose polystyrene (GPPS) is very fragile, has low impact strength and low heat resistance: the softening point of polystyrene is 90-95 ° C.
Various styrene copolymers have the best performance properties. High impact polystyrene (HIPS) is characterized by high impact strength in a wide temperature range (up to -30 ...- 40 ° C). The main disadvantage is low thermal and light resistance associated with the presence of the rubber phase.
