1.DESCRIPTION
The capacitor paper is made from superior sulfate insulating wood pulp, unbleached, uncoated and no any adhesive or filling material. The thickness and texture are uniform. Pinhole, undispersed fibre agglomerates and local defects are allowed by capacitor manufacturing requirements.
2. FEATURES
Excellent electrical, chemical and physical performance
3. APPLICATIONS
It's used for capacitor medium
