Silicone Rubbers

Since our establishment as a silicone softeners manufacturer in 1989, silicone has been our core business, especially custom food and medical grade silicone. SiSiB SILICONES provides a comprehensive range of performance-enhancing products and solutions to better meet the need of customers.

SiSiB SILICONES is a leading manufacturer of silicones, and has
been producing silane coupling agents since 1989.

SiSiB silicone rubber china elastomers have excellent properties, such as heat and moisture resistance, flame retardancy, weather resistance and dielectric properties. They have been ideal candidates for industrial, power transmission, transportation and consumer applications.

SiSiB offers a broad portfolio of high consistency rubber (HCR), liquid silicone rubber (LSR), fluoro silicone rubber (FSR) and RTV-2 silicone rubber for mold-making.

SiSiB HCR products include peroxide and platinum cured silicone elastomers, which can be processed by traditional methods such as extrusion, calendering, compression and transfer molding, or injection molding.

SiSiB addition type silicone elastomer is platinum catalyzed silicone rubber. The platinum-catalyzed reaction is much faster than the reaction initiated by peroxide. It improves productivity and does not produce any toxic by-products. It can improve the mechanical properties of the product (good elongation at break / tear strength / compromise of compression set).

How strong is silicone rubber?
SiSiB fluoro silicone rubber wholesale (FVMQ, FSR) is a durable elastomer that remains stable and low compression set at extreme temperatures. Fluorosilicone rubber contains trifluoropropyl groups, which enhances its resistance to non-polar solvents, fuels, oils, acids and alkaline chemicals. Because of the unique properties, it is widely used in aerospace, automotive, industrial, and aviation applications for static sealing and cushioning. Fluorosilicone is ideal for static sealing applications, but it is not recommended for dynamic sealing operations because of its limited physical strength, high coefficient of friction, and low abrasion resistance. Typical applications include aerospace fuel system components, diaphragms, gaskets, hose lining, seals and O-rings.

SiSiB LSR is a two-component, platinum (addition/heating) curing silicone elastomer. One component contains platinum catalyst and the other component contains methyl hydrogen siloxane as a crosslinking agent and inhibitor. LSR can be molded and cured at high silicone rubber temperature, LSR also has quick cycle times and less raw material handling. The molding process allows for complex part geometries and precise dimensions.

Compared with heat curing rubber (HCR), liquid silicone rubber (LSR) has excellent processing performance, and has benefits such as productivity, precision, biocompatibility and long-term stability. But LSR can only be catalyzed by platinum; HCR can use peroxide or platinum curing process.

SiSiB RTV-2 is a two-part, room-temperature curing silicone rubbers designed for mold-making. It offers great flexibility, tear strength, chemical resistance, and release properties. Silicone molds can be used to cast a variety of materials, including polyurethane, polyester and epoxy resins, polyurethane foam, plaster, wax, concrete, and low melting metals etc. SiSiB offers both condensation curing and addition curing type RTV-2.
