Capacitor gaskets
Advantages
- very low sieve residue
- very low chloride content
- long flow time with short vulcanization time
- high tensile modulus
- low compression set
- good hot air aging properties
- sealing tightness at high soldering temperatures
- avoidance of mold fouling caused by filler
