Silicone PSA

Silicone pressure-sensitive adhesives (Si-PSA) exhibit unique properties, such as high Si–O–Si backbone flexibility, low intermolecular interactions, low surface tension, excellent thermal stability, and high UV transparency, which often explains why silicone PSA has an impressive performance at high- and low-temperature extremes, excellent electrical properties, chemical resistance, and outstanding weathering resistance turning them superior compared to organic PSAs. It is well known that due to their unique properties, silicone pressure-sensitive adhesives are materials for special applications.

The organic pressure sensitive adhesive is mainly produced by the polymerization of siloxane, toluene, and xylene. Compared with the traditional acrylic pressure sensitive adhesive and rubber type pressure sensitive adhesive, it has excellent chemical resistance, water resistance, oil resistance, solvent resistance, high-temperature resistance, low-temperature resistance, heat-resistant degradation, oxidative degradation and so on, and it can be bonded to low surface energy materials.
