I comparison of common sealing strip materials 1. the application temperature range of PVC sealing strips is small, which is unfavorable to environmental protection and harmful to health after long-term application. the European union countries have explicitly restricted the application of PVC, and the application stores of PVC sealing strips will be gradually replaced by TPE, especially the sealing strips used in high-grade manufacturing industries. 2. Silicone sealing material has high aging resistance and cold resistance, but its processing efficiency is not high and its price is expensive, so its main uses are limited. 3.TPE sealing strip not only has good elasticity, but also has the high-quality characteristics of plastic, with wide strength range and environmental protection, which is convenient for processing and recycled for repeated use; Therefore, it is loved by people in windows and doors, furniture, cars and electrical products. Second, the advantages of TPE sealing materials 1. Cold resistance -30℃, high temperature 70℃, good sealing effect, long-term use in the room; 2. Colorless and tasteless, environmental protection, no halogen bulbs, excessive heavy metals and other harmful substances; 3. High production efficiency, simple processing technology, and much faster production rate than rubber; 4. The service life in the room is long, the sealing effect is very good, and it can be purchased and used. Third, the processing of TPE materials 1. TPE sealing strip is generally extruded by single screw, which has simple processing technology, high processing efficiency, wide processing temperature range and fast forming. 2. TPE sealing strip can be co-extruded with PP and PE materials, and has excellent adhesion. 3. TPE materials with different strengths can also be co-extruded and have good adhesion.
