Product description
Parameters
Class F DMD Soft Composites
1. Product introduction
F-grade DMD soft composite material is also called modified polyester film polyester fiber non-woven soft composite material. Three-layer flexible composite material.
This product is suitable for slot insulation, turn-to-turn insulation and gasket insulation of general class F motors and electrical appliances. It can also be used for high-voltage turn-to-turn insulation of Class F dry-type transformers.
2. Size
The width of the soft composite material is 10mm~1500mm, each roll is 20kg~60kg, each roll of 40kg and below should not have more than 3 sections, and each roll above 40kg should not have more than 5 sections, and the length of each section should not be less than 5m.
