Copolymer of STMMA Expandable Styrene/MMA copolymer beads
castchem • STMMA is through Styrene and methyl methacrylate polymer one-step polymerization generated. These products are really have application in lost foam erea. • STMMA’s carbon usually ≤ 0.06%, carburetting defects much less than EPS. • Best use date in three months on 25℃ normal temperature.
Difference of STMMA and EPS • By STMMA is composed of methyl methacrylate and styrene. • 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.
Our new product for Aluminum alloy casting---FD • EPS is extremely backward, we won't say it again. Our factory developed specifically to adapt to the aluminum alloy casting product---FD, it burns more fully than EPS, Carbon defects was less, foaming proportion lighter, only half price of the STMMA.
