Various materials of sealing tape
1. PVC material: This kind of sealing tape makes the life of the du in 1-3 years, and the price is lower, but the zhi is poor in weather resistance during use, hardening, shrinking, and cracking in low temperature, so it is not recommended to choose Strips of this material.
2. EPDM: The sealing tape of this material has a service life of more than 20 years, has good weather resistance, ozone, aging performance, and good comprehensive physical and mechanical properties, but it is not non-colorable and can be hot melted. Waterproof performance is better, so if you are in non-severe cold areas of ordinary engineering, we recommend that you use this type.
3. Thermoplastic elastomer: The sealing tape of this material has a service life of more than 25 years, has excellent ozone resistance, weather aging resistance, and good comprehensive physical and mechanical properties, color can be adjusted, and welded.
