Unsintered PTFE Tape

High-Performance Raw PTFE Tape for Industrial Sealing & Processing Applications

Product Overview

Unsintered PTFE tape is manufactured from 100% virgin PTFE resin without sintering, preserving the material's original fibrillated structure, high flexibility, and excellent conformability. Compared with sintered PTFE products, unsintered PTFE tape offers superior stretchability, better surface adhesion, and enhanced sealing performance.

This type of PTFE tape is widely used in thread sealing, gasket fabrication, chemical sealing, and industrial processing applications, especially where tight sealing and material adaptability are critical.
