Zhejiang Castchem New Materials Co., Ltd.

In 2000, Castchem pioneered the development of STMMA resin specifically for lost foam casting - a polymeric foaming resin that combusts more completely than EPS foam with fewer carbon residues. This innovation significantly reduced surface defects in gray iron castings and resolved the technical barrier that EPS foam couldn't be used for ductile iron castings. The newly developed EPMMA resin for steel castings has achieved the breakthrough of direct steel casting using lost foam resin. Regarding silicone oils, our hydrogen-containing silicone oils feature comprehensive specifications, acid-free stability, and odorless characteristics. The long-chain alkyl silicone oil for high-temperature release agents demonstrates excellent thermal stability, hydrophobicity and anti-fouling properties, offering superior lubrication and release performance for challenging metals like aluminum, zinc, and copper. Castchem’s annual output value is about 27.6 million USD. All products are high-tech products, of which lost foam casting is known 'as the green revolution of the foundry industry’, and has a broad development prospect!
