Inquire about TYPH002 Phenolic Cotton Laminated SheetMechanical applications(coarse weave), with poor electrical properties. Similar to IEC PFCC201. 10 yarn
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
3026:
Mechanical properties(fine weave), poor electrical properties, good machining performance. Similar to IEC PFCC203. 21 yarn
3027:
Mechanical and electrical applications(coarse weave), better electrical properties than other phenolic cotton cloth laminates.
3028:
Mechanical and electrical applications(fine weave), better electrical properties than other phenolic cotton cloth laminates. Recommended for small parts. 32 yarn
