product description

  • SMC material has excellent thermal vulcanizing ability, excellent strength, and electrical insulation characteristic
  • Seat SMC is a press molding material on a sheet with excellent moldability by impregnating unsaturated polyester resin with reinforcing material, filler, mold release agent, pigment, catalyst etc. and increasing viscosity by chemical. Thus, SMC can be adjusted according to the desired physical properties of the product because its change range of strength and various physical properties is wide according to the impregnation and arrangement of glass, which is a reinforcing material, and the filler.
