Silicone pressure sensitive adhesive used in our daily life is relatively more, belongs to the consumption of a product, so the market demand is bigger, also we want to guarantee the quality of silicone pressure sensitive adhesive, a lot of friends all don't know what to do, so in what ways can determine a silicone pressure sensitive adhesive product good? The following will give you a detailed introduction. Silicone pressure-sensitive adhesive generally refers to the pressure-sensitive adhesive with silicone polymer as the main body. The general body is composed of liquid silicone rubber and MQ silicone resin mixed in a certain proportion. Silicone rubber can increase the fluidity of pressure-sensitive adhesive, thus increasing the interfacial adhesive force, and the initial viscosity is strong. However, MQ silicone resin has a great influence on the bonding properties of pressure-sensitive adhesive, because the change of molecular weight of MQ silicone resin makes the viscosity and cohesion strength of pressure-sensitive adhesive change.
Compared with the traditional acrylic pressure sensitive adhesive and rubber pressure sensitive adhesive, silicone pressure sensitive adhesive has excellent chemical resistance, water resistance, oil resistance, solvent resistance, high temperature resistance, low temperature resistance, heat degradation, oxidation degradation resistance and other properties. Moreover, it can be bonded with a variety of refractory materials such as untreated polyolefin (BOPP, PET, PE, etc.) fluoroplastics, polyimide and polycarbonate.
