25 Micron Modified Polypropylene Release Liner For Asphalt Waterproofing Membrane, Oxygen And Oil Barrier
Model: 25TPN-AW
As a modified PP based release film specially designed for asphalt based waterproofing membrane.
This type of product mixes and blows two different raw materials, which not only improves the temperature
resistance but also enhances the tensile strength, elongation and barrier properties.It will effectively prevent
asphalt bleeding out and avoid the adverse chemical reaction with silicone oil layer.
It brings better release performance and maintains the initial viscosity of asphalt.
