PTFE Thin Film
Our cast-and-stretch process creates PTFE films with balanced mechanical strength and optical smoothness, enabling dielectric isolation in eMobility stacks and chemically inert cover layers on diagnostic cassettes.
ISO 14644 Cleanroom
Film casting completed inside ISO Class 7 clean environments.
UL 94 V-0
Thin films self-extinguish to meet electronics safety codes.
Certificates
Comprehensive documentation packages accompany every shipment to simplify validation.
