The typical application range :
Product packaging, household goods (cutlery, trays, etc.), electrical (transparent container, light scattering, insulating film, etc.)
Usually do not need to dry processing unless improper storage. If you need to dry, recommended drying conditions of 80 ℃, 2 – 3 hours.
Melting temperature :
180-280 ℃, Flame retardant materials, a maximum of 250 ℃
Mold temperature : 40-50 ℃
Injection pressure : 200 – 600 bar
Injection speed : Recommend to use a fast injection speed
Runners and Gates can use all the conventional types of
Chemical and physical properties : most of the commercial PS is transparent, non-crystalline materials. PS has a very good geometric stability, thermal stability, optical transmission properties, electrical insulating properties, as well as very small moisture tendency. It is resistant to water, dilute mineral acids, but can be strong oxidizing acids such as concentrated sulfuric acid corrosion expansion and deformation, and can in some organic solvents. Typical shrinkage in the range of 0.4-0.7%.
