Thermoset Raw Materials
Parkway uses three different forms of TST Raw Materials:
1) Bulk Molding Compound (BMC) – A blend of various inert fillers, fiber reinforcement, catalysts, stabilizers, and pigments that form a thick, putty-like compound
2) Sheet Molding Compound (SMC) – A compression molding compound often used for larger parts where high mechanical strength is needed
3) Thick Molding Compound (TMC) - These TST materials are manufactured using a unique process that produces a material with the best combined properties of a BMC (excellent flow properties) and SMC (excellent mechanical properties).
4) Dough Molding Compound (DMC) - A TST material that consists of polyester resin, glass fiber, calcium carbonate, lubricants and catalysts.
