Phenolic cotton sheet
1>Mechanical applications,with poor electrical properties.
2>Mixed mode backing material.can substitute for some cotton cloth
3025
Mechanical applications(coarse weave), with poor electrical properties. Similar to IEC PFCC201.
3025B 3025C 3025CS
Mechanical applications being economical products versus 3025. 3025CS has abrasion proof property, but it is not recommended to be used as insulation material.
3025D
Mixed mode backing material. It can substitute for some cotton cloth laminates
