1. Adapt to the deformation and cracking of the substrate
High tensile strength and elongation rate, strong adaptability for substrate shrinking distortion and cracks;
2. Outstanding low temperature resistance
Superier high & low temperature resistance, could keep its functions at -50degree and be used in cold or hot areas, especially in cold areas;
3.Excellent physical properties
Good resistance to tearing, fatigue, corrosion, mold and breakage.
