PMP
PMP is a a few layer composite insulation paper made of large quality presspaper laminated on the two sides of polyester movie.
Edge:
PMP has outstanding dielectric strength, higher original tear strength and tear toughness
Functionality:
one. Excellent dielectric energy
two. Higher initial tear energy and tear strength
3. Heat resistance is Course F
Application:
PMP is widely relevant for slot insulation, phase to phase insulation and liner insulation in electrical motors and electrical equipment.
