What are the unique properties of silicone pressure-sensitive adhesives?
silicone pressure-sensitive adhesive is a dry material with dry tack and permanent tack. Adhesive tape is the main form of use of silicone pressure-sensitive adhesive tapes. With the light pressure of a finger or palm, the silicone pressure-sensitive adhesive tape can be firmly adhered to the surface of the substrate, and can be peeled off from the surface of the adherend without leaving traces of adhesiveness. The vast majority of commercial pressure-sensitive adhesives are rubber-based and lactone-based, widely used in various fields of the national economy, and are indispensable materials for modern life and various industries.
Silicone pressure-sensitive adhesives not only have adhesion to metal, paper, glass, fabric, Plastic and other surfaces like general organic pressure-sensitive adhesives, but also have good adhesion to low-energy surfaces such as polytetrafluoroethylene and silicone rubber products. It is the only pressure-sensitive adhesive that can be used in the temperature range of -65 ～ 300 ℃, and has very good electrical properties, non-corrosive to metals, and non-irritating to the skin.
Silicone pressure-sensitive adhesive (hereinafter referred to as SiPSA) not only has adhesion to the surfaces of metals, paper, glass, fabrics, plastics, etc., but also has low energy surfaces such as polytetrafluoroethylene and silicone rubber products. Good adhesion, is the only pressure-sensitive adhesive that can be used in the temperature range of -65 ~ 300 ℃.
Mainly used as heat-resistant tape, H-level electrical insulation tape, mica tape for refractory wires, wave soldering shielding film for circuit substrates, plating masking tape, low temperature resistant tape, medical tape, bonding of silicone rubber keys, silicone release Areas such as overlaps where organic pressure-sensitive tape cannot be used.
