PVC material: the sealing strip of this material has a service life of 1-3 years and a low price. However, due to poor weather resistance, it is not recommended to choose this material in case of low temperature hardening, shrinkage and cracking.
EPDM: The sealing strip of this material has a service life of more than 20 years, good weather resistance, ozone resistance, aging performance, and good comprehensive physical and mechanical properties, but it cannot be toned, and the waterproof performance of the hot melt processing interface is better. Therefore, if you are in ordinary engineering non-cold areas, we recommend that you use this one.
Thermoplastic elastomer: This material of the sealing strip has a service life of more than 25 years, has excellent anti-ozone, weather aging resistance, and also has good comprehensive physical and mechanical properties, adjustable color, and can be welded. So no matter what the situation and what region, you can choose this material.
