TFE250 is a 4:1 Ratio PTFE heat shrinkable tubing which has almost total chemical and solvent resistance. TFE250 will withstand a continuous operating temperature of 250°C, has extremely high electrical resistance and total resistance to UV radiation. Teflon has many applications throughout industry, and its unique properties allow these tubings to solve problems not possible with other materials.
