Characteristics & Applications:1. 5：Mechanical applications(coarse weave), with poor electrical properties2. 5B, 5C, 5CS, 5B and 5C are ecomomical products versus 5; 5CS is suitable for abrasive-resistance parts, but not recommended to be used as insulation material3. 6：Mechanical properties(fine weave), poor electrical properties, good machining performance 4. 7：Mechanical and electrical applications(coarse weave), better electrical properties than other phenolic cotton cloth laminates5. 8：Mechanical and electrical applications(fine weave), better electrical properties than other phenolic cotton cloth laminates. Good machining performance, recommended for small parts(as in type 6)
