Phenolic cotton cloth laminate sheet is made of cotton cloth impregnated with phenolic resin after drying and hot pressing.
Type: 3025/3025B/3025C
Features:
1.Normal Dimension:
1020mmx1220mm,1020mmx2040mm,1220mmx2470mm
2.Normal Thickness: 0.5mm to 50mm
Advantage:
With electrical properties and good mechanical properties under normal conditions.
Application:
Primarily intend for mechanical applications. Not recommended to use for electrical applications. 3025B and 3025C not stronger than 3025, but more economical than 3025, similar to NEMA's C grade.
