High Dielectric Polytetrafluoroethylene Sleeve is available in all standard solid colours including natural opaque. The Polytetrafluoroethylene Sleeve can work for a specific temperature of -200 degree C to +250 degree C and has high dielectric strength. The Polytetrafluoroethylene Sleeve is un-effected by soldering temperature and provided with smoother internals to allow closer fit. High Dielectric Polytetrafluoroethylene Sleeve is resistant to UV radiation and water absorption.
