With the development of Fenestration industry, the physical properties of the doors and windows of more and more people's attention. The doors and windows sealed plastic strips in the doors and windows of the five performance plays a very important role in sealing strip doors and windows will affect the level of quality of performance, thereby affecting the life of the doors and windows. Doors and windows sealed plastic strips also with the development of the industry have a better improvement, initially cheap rubber, PVC strips by a gradual transition to the EPDM (EPDM) rubber strip applications. EPDM tape has good flexibility, heat resistance, low-temperature impact performance and anti-aging properties. Currently, the market for alternative EPDM sealing tape products have emerged, and has begun to be applied to engineering practice. Is a thermoplastic elastomer material, commonly known as TPE sealing strip, the price is higher than the EPDM seals. This material has both thermoplastic processing performance, but also has the physical properties of vulcanized rubber, it can be described as a combination of plastic and rubber advantages advantages.
