Product Description

1. Define and purpose
3025 is formed through drying and heat pressing after the cotton fabric dips into PF resins. 3025R is formed as laminated board through heat pressing after the blanc dips into PF resins. 3025 has high mechanical performance and is used as insulation structural components for machinery, electric engine and electric equipment, as well as used in transformer oil. 3025R has very high mechanical strength, suitable to be used as the components of mechanical products such as the bush of rubber cloth gears, guide wheel.

2. Technical Data
2.1 Outside appearance
Laminated board surface should be flat and tidy. The bubbles, sand holes and inclusions are not allowed. A little of spots are allowed. The edge should be cut tidy. There is no delaminating problem and crackle on end surface.
