What is the impact of TPO waterproofing membrane welding performance?
Dow Chemical TPO and Basel TPO due to the different grades of production technology, raw material ratio is different from the formula system for the performance of the material melting point, polymerization, molecular weight distribution index, melt index, melt strength, weldability are not same.
It is recommended that attention be given to the above factors in the course of the test
2. The surface cleanliness of the web;
3. Does the welding temperature match the welding speed;
4. Welding method, test welding, manual three-step welding.
Factors affecting the welding performance of TPO coil mainly in the following areas:
1. Material melting point and welding window;
