SAN Resin Material Properties & Uses
Styrene Acrylonitrile (SAN Resin) is a transparent thermoplastic known for its clarity, rigidity, and excellent chemical resistance. As a copolymer of styrene and acrylonitrile, SAN resin offers improved thermal properties over standard polystyrene, making it an ideal material for products requiring greater durability and heat resistance.
At PMC, we bring deep expertise in working with SAN resin, offering reliable injection molding solutions for a range of consumer, medical, and industrial products. Our team helps clients navigate resin selection, design optimization, and production to ensure every part meets performance, aesthetic, and regulatory requirements.

| San Resin Applications | Styrene Acrylonitrile resin is a copolymer plastic commonly used in place of Polystyrene due to its greater thermal resistance. SAN copolymers are produced by the polymerization reaction of styrenes and acrylonitrile. The properties are dependent on the acrylonitrile content. Commercial grades of SAN offer different acrylonitrile molecular masses. The transparency of SAN makes it one of the few plastics that can be used in clear applications. It’s glass-like clarity makes it a preferred plastic in the housewares market. SAN is commonly used in the following applications:
