Features:

A, mechanical properties: high strength, fatigue resistance, dimensional stability, creep is also small (there is little change under high temperature conditions);

C, solvent resistance: no stress cracking;

D. Stability to water: easy to decompose in water (caution should be used in high temperature and high humidity environment);

Advantages:

Polystyrene acid alkali resistance and low energy alcohol, by many hydrocarbons, ketones, high fat fat erosion and softening, soluble in aromatic hydrocarbons.

Electric insulation is good, is a good high frequency insulation material, has excellent and arc.

Polystyrene is a highly transparent material with a high surface gloss. Easy to print.

Polystyrene can be colored freely, odorless, tasteless and non-toxic, not fungal growth.
