Silicone rubber self-adhesive tape
Silicone rubber self-adhesive tape
Silicone rubber self-adhesive tape is made of high temperature resistant laminating tape adhesive inorganic silicon rubber. The tape has an easy-peel protective layer. It can be used at H-class high temperature 250 ° C (365 ° F). The outermost layer of the terminal can withstand electrical marks.
Wide application area, large quantity, excellent performance, anti-fouling, anti-hydrochloric acid, anti-ultraviolet, waterproof; oxygen resistance, ozone resistance, cold resistance, heat resistance, high pressure resistance, etc.
Methyl vinyl silicone rubber as base material, fumed silica as filler, hydroxy silicone oil as structure control agent, 2,4-dichlorobenzoyl peroxide as vulcanizing agent, boron-containing polysiloxane as tackifier Agent, adding aluminum hydroxide and silicon micronized powder, etc., to obtain flame retardant silicone rubber self-adhesive tape for electric power. The effects of the type and amount of tackifier, aluminum hydroxide, and silicon micronized powder on the properties of silicon rubber self-adhesive tape were studied. The results show that boron-containing tackifiers can improve the self-adhesion of silicone rubber, and that silicon fine powder and aluminum hydroxide have a synergistic effect to improve the flame retardancy of silicone rubber. The preferred formula is: 100 parts 110-2 silicone rubber, 4 parts Hydroxyl silicone oil, 40 parts of fumed silica, and 16 parts of tackifier, 60 parts of aluminum hydroxide and 20 parts of silicon powder. The silicone rubber self-adhesive tape obtained according to this formula has a flame retardant rating of FV-0. , Self-adhesive force of 8.2 N / cm, tensile strength of 4.5 MPa, elongation at break of 307%, electrical strength of 23.2 kV / mm.
