Compared with traditional pressure-sensitive adhesives in China, silicone pressure-sensitive adhesives have excellent properties such as chemical resistance, performance stability at extreme temperatures and dielectric properties. Among all pressure-sensitive adhesives, silicone pressure-sensitive adhesives have a critical temperature value that makes them perfect for use in almost any environment on earth (high temperature critical value: 300℃, low temperature critical value: -75℃). In some places where environmental requirements are relatively high, silicone pressure-sensitive adhesives have almost no pressure. In addition, it can also bond a variety of refractory materials, such as non-surface treated polyolefin, fluoroplastics, polyimide and polycarbonate, which can not adhere to the base surface of ordinary pressuresensitive adhesives. The experimental results of silicone pressuresensitive adhesives are satisfactory.
