Product Code:SAE AMS3588
Title:Plastic Tubing, Electrical Insulation, Irradiated Polyolefin, Clear, Very Flexible, Heat Shrinkable 2 to 1 Shrink Ratio
Issuing Committee:Ae8-D Wire And Cable Committee
Scope:This specification covers an irradiated, thermally-stabilized, modified polyolefin plastic in the form of thin-wall, heat-shrinkable tubing with a low recovery temperature. This tubing has been used typically as a very flexible, electrical insulation tubing whose diameter can be reduced to a predetermined size by heating to 100 degrees C (212 degrees F) or higher, but usage is not limited to such applications. This tubing is stable for continuous exposure from -55 to +135 degrees C (-67 to +275 degrees F).
