* Density suggestion is a function of utilities and expander capabilities; the above values represent optimum expansion conditions. | |||||||
*The select of beads size shall be according to the min thickness of the casting wall, used to be 1/10 of it. For example, you could choose the 700 µm szie beads if the casting's thinnest wall is 7mm. If the casting needs a high precision, it can also choose the next small class. | |||||||
*Contains an additive which quickly reduces the molecular weight of polystyrene at elevated temperatures. Recommended for applications in aluminum having fold defects and applications in iron having excessive lustrous carbon in castings. | |||||||
*Typical Application means we have tested in this kind of metal, metals beyond that are according to be actually used. |

Castchem is an USA-Sino joint venture chemical company, It has 2 plants separately located in Hangzhou and Quzhou, I'm the Oversea Director of both plants.
Castchem Hangzhou is a chemical manufacturer specialized in producing the lost foam casting pattern raw material STMMA co-polymer(American patent US 6770 681 B2).It has much better performance than polymers such as EPS(expandable polystyrene) or EPMMA because it is copolymerized from PS and MMA.
Lost foam casting(or evaporative-pattern casting, gasifiable patterns castings,LFC process)is particularly used for very complex casting, it is cost saving because it does not need as much machining as traditional casting. We developed the STMMA polymer series to meet all kinds of metals lost foam casting required both in ferrous and non-ferrous, to reduce such as fold defects,surface recarburization defects.Currently there are four different raw material used to foam patterns, including EPS,EPMMA,copolymer and polymer mixtures.Copolymer has been finally proved the best chemical for LFC process.
Castchem Quzhou is our another production base for Methyl Hydrogen Silicone Fluid 202(polymethylhydrosiloxane,PMHS), CAS 63148-57-2, could be used as waterproof agent in fabric,glass,ceramics,paper,leather,metal,cement,marble and other materials.Also could be used as cross-linked agent in silicone gel,raw materials in modified silicone oil,anti yellow agent of silicone rubber,anti-sticking agent for paper etc.
