SMC Insulating sheets
SMC Insulating Sheet is made from chopped fiberglass strands impregnated with unsaturated polyester resin through high temperature and high pressure molding process. It is a kind of excellent FRP insulator. The SMC Insulating Sheet can be made into various colors.
APPLICATIONS.
- Mechanical / Electrical Application: electronic insulating board of high or low voltage switchgears, insulation structural parts, air conditioner bases, mechanical parts, machine & instrument casings, electronic / electric laminated sheet boards, etc.
-Transportation Application: Car door panels, hoods, cable boxes, odometers, instrumental panels, shades, etc.
- Building Materials: Door panels, water tanks, purification tanks, ceiling panels, wall panels, bathroom water proof panels, sinks, bathtubs, etc.
- Furniture Industry: Chairs, tables, work table face panels, student desks & chairs, screens, etc.
Product characteristics:
High mechanical strength.
Good flame retardancy
Flame retardancy and proof tracking
Excellent dielectricity, high voltage resistance
Low water absorption ratio, Good Dimensional Stability and low warp
