3025 phenolic cotton cloth laminated sheet
It is prepared from cotton fabric impregnated with phenolic resin by pressing under high temperature and pressure. The 3025 is mainly used for insulating construstion parts in machines electrical motors and equipments, eg. Gear-wheel, gear-slip etc. And can be used in transformer oil.
Features:
1. Very high mechanical strength, particularly, impact resistance strength.
2. Common dielectric properties used for electrical equipments with low voltage.
3. Good abrasion resistance and processing properties, beared various machining processes.
4. size: 0.5mm-200mm width:1020*2040mm
