Second Layer: Adhesive (AD) 170 ~ 250µm
Third Layer: Polyethylene (PE) 2.5 ~ 3.7mm
Key Features:
Extends service life from 5-10 years up to 30-50 years
Outstanding mechanical strength, superior electrical insulation
fully waterproof, abrasion-resistant
highly anti-aging
Engineered for extreme environments and aggressive, corrosive conditions
