Product Code:SAE AMS3639
Title:Tubing, Irradiated Polyolefin Plastic, Electrical Insulation, Clear, Semi-Rigid, Heat-Shrinkable, 2 to 1 Shrink Ratio
Issuing Committee:Ams P Polymeric Materials Committee
Scope:This specification covers an irradiated, thermally-stabilized, modified polyolefin plastic in the form of semi-rigid, thin-wall, heat-shinkable tubing. This tubing has been used typically as a semi-rigid, electrical insulation tubing whose diameter can be reduced to a predetermined size by heating to 120 degrees C (250 degrees F) or higher, but usage is not limited to such applications.
