Polyester glass fiber products Your location:home > Products

  Polyester glass fiber materials is made of electrical alkali-free glass fiber yarn impregnated in polyester resin and mixed with low shrinkage additive packing and various additives after hot pressing.
  SMC is the abbreviation of Sheet molding compound whose main materials are glass fiber, unsaturated polyester, low shrinkage additive packing and various additives.
  SMC products all are with excellent electrical,mechanical applications,heat stability,chemical resistance noncorrodibility,widely used for electrical industry insulation parts,accessories of cars,trains,structural components of communication engineering and the shell of explosion-proof electric equipments,etc.
  DMC(BMC)is whose main materials are chopped glass fiber, unsaturated polyester, additive packing and various additive and mixed into pre-impregnating materials.DMC(BMC)products all are with excellent electrical, mechanical applications, heat stability, chemical resistance noncorrodibility, which could meet various requirements, such as for transmission components, intake pipe, air MenFa cover, bumper and aircraft, construction, furniture that require earthquake-proof, flame resistance, beautiful and durable.

  Size: 1000×1200mm; 1250×2000mm;1000×2000mm
  Thickness: 2 ~80mm

  Customers special requirements on specifications could be negotiated case by case.
