Characteristics
1. High tensile strength, good elongation, strong applicability for base expansion or cracking deformation.
2. Large width, high construction efficiency, small product consumption.
3. Good diffusion of water vapor, easy discharge of condensate, easy discharge of moisture left in the substrate.
4. Root penetration resistance, chemical corrosion resistance and aging resistance.
5. Maintain good flexibility even at -25ºC.
6. High Security without open flame installation.
7. It used for exposed, service life 10 years; if unexposed used, the service life can be 50-100 years.
8. The artificial weathering time of OTAi PVC is not less than 4100 hours.
9. Anti-Wind reach 135 PSF.
