Silicone rubber is considered as the most commonly utilized synthetic polymer. It contains a bonding structure comprising of oxygen, hydrogen, and carbon which are the fundamental elements found in quartz, sand, and glass. This makes it a distinctive synthetic polymer with strong crosslinks which are silica reinforced. These awesome features of silicone rubber offers a perfect balance between the chemical and mechanical properties that surpasses the standards of most industrial applications today. Lets explore the benefits associated with silicone rubber and see why so many of us prefer silicone rubber.

Versatility and stability of silicone rubber are key characteristics that makes it more reliable in the sense that they can serve for a considerably longer time thereby reducing its cost in the long run. Silicone rubber exhibit great tensile strength, compression resistance, and elongation as compared to conventional rubber products. The tear strength of silicone rubber is estimated to be about 9.8kN/. Through careful modification of silicone rubber polymers with crosslinkers and fillers, higher strength can be achieve in silicone rubber ranging from 29.4-49kN/m.

Its versatility is defined by the ease at which the polymer is mixed and blended. Silicone rubber can be mixed and molded into finished products with various unique physical and chemical properties to suit your requirements.

For example, its excellent resistance to extreme temperature ranges, -30 oC to 230 oC. Specially blended silicone rubber can even withstand a temperature of 350oC at intermittent exposure without variation in its mechanical and physical properties. Unbeknownst to many, silicone rubber has sneaked its way into our lives and provided many conveniences to us.

The recyclability of silicone rubber makes it more environmentally friendly and there is minimal pollution during its production. Unlike other plastics, it is nontoxic and inert which minimizes the chance of leaching hazardous chemicals that may contaminate food in silicone rubber based utensils. It is also stain resistant and odor free. Additionally, it is resistant to Ozone and Ultra-Violet (UV) exposure, moisture resistant and also chemical resistant. Traditional rubber material will harden and deteriorate when used outdoors and exposed to the Sun.
