phenolic cotton sheet
3026
Mechanical properties(fine weave), poor electrical properties, good machining performance. Similar to IEC PFCC203.
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.
