Problems solved by technology

The deficiencies of these sealing materials are more obvious: short service life, poor high temperature resistance and low temperature performance, fast aging speed, and peculiar smell, easy to crack, etc. For this reason, those skilled in the art have developed multiple improved materials, but, after The trial effect is still not good, especially in the situation that people's living standards are constantly improving and environmental protection requirements are gradually increasing. The market for sealing materials for high-end cars, high-grade aluminum alloys, and plastic steel doors and windows is in urgent need of a non-toxic, tasteless, high-temperature resistant And sealing material with good low temperature resistance and good sound insulation effect
