PTFE heat shrink tubing is made of high-performance medical grade polytetrafluoroethylene material. polytetrafluoroethylene has the best physical properties of plastics, with the highest performance in electrical properties, low friction coefficient, solvent resistance, and high temperature resistance. Its uniform structure helps to ensure consistency and high performance, making the product almost free from defects, pinholes, seams, cracks, or miscellaneous points.
