ITW Formex

ITW Formex is a flame-retardant polypropylene (PP) insulation material widely used in the electronics and electrical industries. It provides an excellent balance of electrical insulation, flame resistance, mechanical durability, and ease of fabrication. Formex sheets can be easily die-cut, folded, and thermoformed, making them an ideal choice for insulating barriers, shields, and enclosures in electronic devices. The material is UL 94 V-0 certified, halogen-free, and RoHS compliant.

Features:

  • Flame-retardant polypropylene (PP).
  • Excellent electrical insulation and dielectric strength.
  • UL 94 V-0 flame retardant, halogen-free.
  • Lightweight, flexible, and easy to process (cut, fold, form).
  • Chemical and moisture resistance.
  • Cost-effective alternative to traditional insulation boards.

Applications:

Electrical insulation barriers in power supplies and chargers, Insulating shields in consumer electronics and office equipment, EV battery insulation and compartment barriers, Transformer and motor insulation components, Enclosure and housing liners for improved safety.
