What is the sheet molding compounds (SMC)

SMC is an abbreviation for sheet molding compound, which is a high strength glass fiber reinforced thermoset, moulding material which is normally compression moulded. It combines glass fiber and unsaturated polyester/phenolic/vinyl and acrylic modified resins, fillers (calcium carbonate), catalysts, pigments and stabilizers, release agents to produce a high strength moulding compound.

Why SMC material is superior?

All parts of our covers are used high strength of thermoset SMC composites which made by our company.
SMC—sheet moulding compounds, refers to the reinforced unsaturated glass fiber resin sheet molding compound which is mainly composed of unsaturated resin, glass fiber, filler and functional additives, is one kind of high performance composites used for compression molding.
The main components including glass fiber, unsaturated polyester resin, filler and related additives.
This material use glass fiber as reinforcing material. So the SMC material has good wear proof.
The material has good fatigue resistance and long service lifespan.
Manufacturing process: under the condition of high temperature and high pressure, with large hydraulic equipment one-time molding, without any steel reinforced material.
Meeting the standards of EN124:1994 and Australian Standard of AS3996-2006.
