Sell STMMA (Styrene-Methyl Methacrylate Copolymer)- new lost foam casting resin

Description

STMMA copolymer resin series(Styrene-Methyl Methacrylate Copolymer)

We specially produce STMMA copolymer resin series mold materials for foam lost casting, including STMMA, STMMA-FD and STMMA-FC foamable copolymer resin beads, and they are mainly used to produce castings for valves, pipings, car fittings and various machinery fittings.

Compared with EPS, STMMA series foamable copolymer resin beads have much excellent casting performances:
Reducing carbon defect of castings;
Reducing carburization defect on surface of steel castings;
Reducing smoke carbon;
Improving surface finish of castings
