1. Discription:
The polyimide laminated sheet has high mechanical and dielectric properties applied in electronics, electrical appliances,equipment for insulation instructural parts, and in the humid environment and transformer oil.
2. The material:
They are made of alkali-free glass cloth or polyester fiber cloth or other reinforced materials.
3. The process:
Vacuum impregnated products are a kind of insulation product without the gap. They are vacuum treated in special moulds and then produced with solvent-free resin filled under high pressure.
The insulation sheet we make have Class B, F, H, the heat resistance of Class B is 130°C, Class F 155°C, Class H 180°C.
