Product Description

Product Description：

The STMMA is an expandable Co-polymer resin beads developed for foamed patterns of lost foam casting process, it is co-polymerization reacted by liquid methyl methacrylate monomer and styrene monomer. Compared with the EPS, STMMA carbon molecule content has been greatly reduced in order to eliminate carburization defects in the process of lost foam casting. This formula Co-polymer product was designed for high-quality required valves, pipe fittings and machinery parts, especially made of gray iron, ductile iron and low-carbon steel.

Advantages of STMMA co-polymer:

Reducing carbon defects of castings;

Reducing carburization defects on the surface of steel castings;

Reducing smoke carbon;

Improving the surface finish of castings

Total carbon increase after pouring can be controlled to less than 0.*4%.
