Product Name: STMMA Co-polymer Resin Beads Expandable
Chemical components:EPS+PMMA
STMMA is Specifically designed for lost foam casting by CastChem.
*Each of the above products is available in 25kgs bags or 125kgs drums.
The Castchem STMMA Formulation VS EPS for Lost Foam
*CastChem developed 20 years ago an advanced casting formulation STMMA for Lost Foam, and it had been granted an American patent.
*CastChem developed STMMA-FD formulation in 2016, specially used for aluminum lost foam cast, also with a relatively low price that easy to be accepted by the foundries.
*CastChems STMMA series contains less carbon molecules than EPS, so it can reduce or eliminate fold defects and excessive lustrous carbon in castings which has been proved by our users in China and American such as BMW,GM,and Anhui QuanChai Engine.
Lost Foam Advantages vs Traditional Casting
*Lost Foam Casting is particularly used for very complex casting. This process eliminates cores
