Capacitor Literature

Technology Types

Inclined Wire Technology

  • Ability to produce thin and light webs
  • Regular and superior absorption of the electrolyte
  • Perfect consistency in thickness and basis weight
  • Worldwide leadership position in lightweight long-fiber materials
  • Basis weight down to 9.0 g/m²
  • Regular ultra-low ESR of the impregnated material
  • Best compromise in sheet formation – tensile strength and low ESR

Flat Wire Technology

  • Production of material with higher density for high- and medium-voltage applications
  • Consistency in thickness and basis weight

Capacitor Materials

Many of our capacitor materials contain sustainable abaca fibers, which are delivered from Glatfelter’s own dedicated pulp production facility in the Philippines. This allows us to provide you with unrivaled consistency in quality and supply. Our kraft materials are produced with PEFC certified pulp (PEFC /04-31-2118).
