Foamed silica gel
Foamed silica gel and additive liquid foam rubber are composed of two-component vulcanized viscose silicone rubber, white paste like liquid in color, and become soft elastomer materials after vulcanization.
Advantages: soft and light, good handle, high foaming ratio. Disadvantages: honeycomb physical structure, easy to deform during bonding;
Foamed silica gel application:
① Foaming silica gel and additive liquid foaming silicone rubber are used to make flexible silicone rubber products, such as silicone breast pads, shoulder pads, silicone foam boards, anti-skid pads, etc.
② Silicone foam sealing strip, silicone foam coiled material, anti-seismic silicone foam board, copier transfer roller sponge tube, silicone foam insulation tube, etc. are shock absorption and cushioning accessories, and can also be used to fill bags and other products.
Sticking foaming silicone glue
① Foamed silica gel glued with silica gel glue is thermally vulcanized. The machine is bonded with hot vulcanized silicone glue. However, it should be noted that the foaming silicone rubber sheet, rubber pad and rubber strip catalyzed by platinum curing agent are made of A: B two-component. The bonding effect of silicone foam cured with peroxide catalyst is better.
② Foamed silica gel glued with silica gel glue. After bonding at room temperature for 24 hours, it absorbs moisture in the air and solidifies.
③ The instant adhesive that can stick silica gel is not recommended to be used for bonding of foamed silica gel products. As pressure is required during bonding, it is easy to cause whitening and deformation of the bonding area. Affect the beauty of the product.
