UF508 White Surface Material Anti Corrosion Film
Description:
What's Anti Corrosion Film?
It is a surface material, use PET film laminated with fluorine film, make the film high strength and aging resistance(More than 25 years). Make it it an ideal material for surface material of waterproofing membranes, butyl tapes, underlayment and so on.
Structure:
Inner side, it is PET film (Thickness: 0.05mm or 0.1mm, High Strength, Tear Resistance);
Outer side is white fluorine film (Thickness:0.025mm, Aging or Weather resistance, up to 25 years).
Advantages:
| 1. Excellent properties of anti-aging, more than 25 years |
| 2. UV resistance |
| 3. Reflectivity of over 80%-85% sunlight |
| 4. Chemical corrosion resistance |
| 5. High strength, tear resistance |
