The specification of the tape consists of two layers, adhesive layer and film backingAdhesive: butyl rubber.
Adhesive: butyl rubber
Film backingr: Special blend of stabilized polyethylene



Ⅲ Features:
Excellent adhesion to inner-layer tape and self
Resistant to UV
Can be applied over a wide temperature range
Good conformability and consistent uniform thickness
Easily applied with no special equipment
Compatible with common pipe coatings
Excellent resistance to cathodic disbonding
Meets ASTM D 1000 StandardCold applied
