Raw material

SAN is an abbreviation of styrene-acrylonitrile. It is a copolymer consisting of about 70% styrene and about 30% acrylonitrile. The result is an amorphous and transparent polymer which has improved mechanical properties compared with the bulk plastic polystyrene. SAN has a glass transition temperature of over 100 ° C, which allows you to use the material in applications which has contact with hot water.
