| Appearance |
|
"The surface should be smooth, flat, uniform in thickness, free of impurities, folds, bubbles, wrinkles, holes, etc. The product should be soft and should not stick when unrolled." |
| Dimensions |
mm |
"Length: The prepreg is supplied in rolls, with an outer diameter of not less than 200mm, a length of not less than 50m, and a weight of not less than 20kg. There are no more than 2 sections per roll, and each section is not less than 5m. There are obvious markings at the section head." |
| |
"Width: The width of each roll of prepreg should be consistent. The width can be cut into various specifications and sizes according to user requirements, ranging from 10-1000mm, with a tolerance of ±1.0mm." |
| Storage requirements |
|
"The product should be stored below 40ºC in a dry, clean and well-ventilated warehouse, away from fire, heat sources and sunlight. The product storage period is 6 months." |
Product material: polyester film polyester fiber non-woven fabric soft composite material
Product process: impregnated with heat-resistant epoxy resin and cured
Product size: long pre-impregnated cloth is supplied in rolls, the outer diameter of each roll is not less than 200mm, the length of each roll is not less than 50m, and the weight is not less than 20 kg
Product features: good electrical properties, heat resistance, flame retardancy, and long storage period at room temperature
Product introduction: F-class epoxy resin pre-impregnated DMD is made of polyester film polyester acetate fiber non-woven fabric soft composite material, impregnated with heat-resistant epoxy resin and cured. Heat-resistant epoxy resin non-woven pre-impregnated resin non-woven fabric (HTEPP) has excellent electrical properties, heat resistance, flame retardancy, and long storage period at room temperature. It can be used as interlayer insulation of low-voltage coils of dry-type transformers and F-class motor slot insulation and interphase insulation.
