Sheet molding compound (SMC) is one of the most widely used forms of composite material in the automotive industry. It is a high-strength composite material comprising primarily athermosetting resin, filler (s), and fiber reinforcement. Thermosetting resin is typically based onunsaturated polyester, vinyl ester, phenolic, or a modified vinyl urethane.
Features and applications
Fire retardant, low smoke properties.
Railway seats, window frames, partitions, air conditioning covers, etc.

3. Recommended pressing process
1. Pressing time: In principle, the pressing time is about 1min per 1mm of product thickness. Adjustable according to the actual situation.
2. Pressing temperature: Front side (bright side of the product)/back side: 146-150ºC/138-142ºC - Temperature of the mold surface.
3. Molding pressure: More than 100Kgf/cm2.
4. Storage, shelf life and others
SMC should be sealed and packaged with aluminized film, and stored in a cool and ventilated place below 25°C. The shelf life is 2 months from the date of production.
Please read the Product Safety Data (SDS) carefully, before using.
