Medical & Biotech
Biocompatible membranes and high-purity laboratory instrument seals.

Frequently Asked Questions (FAQ)

Q: What makes Oriented PTFE Film different?
A: Oriented film is stretched during the manufacturing process, which increases its tensile strength and dielectric strength in the direction of the orientation, making it ideal for high-precision electrical wrapping.

Q: Can Cylex Plastics provide custom widths for non-standard requirements?
A: Yes. As a provider of precision-machined solutions, we can skive and cut PTFE films to your exact width and thickness requirements beyond our standard chart.

Q: Is the film resistant to extreme chemicals?
A: Yes, our virgin PTFE film is chemically inert to almost all industrial solvents, acids, and bases, except for molten alkali metals and fluorine at high temperatures.
