PolyK Piezo PVDF film & powder

In-house roll-to-roll production of piezoelectric PVDF film with thickness from 10um to > 200um: consistent quality and low cost.
For R&D in high energy density capacitor, piezoelectric, pyroelectric, electrocaloric ECE & electroactive polymer EAP.
Include 20 grams of each of Seven typical polymer resins based on P(VDF-TrFE).

PVDF Film

  • Beta Phase PVDF film (non poled) with high optical transparency : you can design your own poling pattern for special applications.
  • Poled PVDF film with high d33 and d31 with our proprietary film production and poling process using the best reisn.
  • Produce special thickness film based on application with short lead time.
  • Supply paper-size film for R&D to > 100m long film for OEM, quick deliver.
  • Special electrodes can be applied based on required : sputtered gold, silver paste, etc.
