PMP
PMP is a three layer composite insulation paper made of high grade presspaper laminated on both sides of polyester film.
Advantage:
PMP has excellent dielectric strength, high initial tear strength and tear strength
Performance:
1. Excellent dielectric strength
2. High initial tear strength and tear strength
3. Heat resistance is Class F
Application:
PMP is widely applicable for slot insulation, phase to phase insulation and liner insulation in electric motors and electrical apparatus.
