1. DESCRIPTION
The capacitor paper is made from superior sulfate insulating wood pulpunbleacheduncoated and no any adhesive or filling material. The thickness and texture are uniform. Pinholeundispersed fibre agglomerates and local defects are allowed by capacitor manufacturing requirements.
2. FEATURES
Excellent electricalchemical and physical performance
3. APPLICATIONS
It’s used for capacitor medium
