At NINGBO INNO PHARMCHEM CO.,LTD., we believe that understanding the fundamental science behind our materials is key to unlocking their full potential. Silicone rubber, particularly the hydroxyl-terminated RTV 107, is a prime example of a material engineered for exceptional performance, largely due to its inherent chemical stability and remarkable thermal properties. These characteristics make it a cornerstone in numerous demanding industrial applications.

The backbone of silicone rubber is a siloxane polymer chain, consisting of alternating silicon and oxygen atoms (Si-O-Si). This unique inorganic backbone, unlike the carbon-based chains found in organic polymers, grants silicone rubber its superior thermal stability and resistance to degradation. The Si-O bond is significantly stronger and more stable than the C-C bond, allowing silicone rubber to withstand a wide range of temperatures without breaking down. This is why RTV 107 can maintain its flexibility and integrity from -60°C up to 200°C, a far broader range than most organic elastomers.

Furthermore, the chemical stability of silicone rubber is a significant advantage. The silicon-oxygen backbone is resistant to oxidation, UV radiation, ozone, and many chemicals, including acids, bases, and solvents. This inertness ensures that the material does not readily react with its environment, maintaining its physical properties and functional integrity over extended periods. For applications requiring resistance to harsh chemicals or outdoor exposure, silicone rubber provides a reliable and long-lasting solution. When manufacturers seek to buy silicone rubber, these properties are often the primary drivers for selection.

The flexibility of RTV silicone rubber is also a direct consequence of its molecular structure. The Si-O bond angle allows for greater chain mobility compared to the more rigid carbon-carbon backbone. This inherent flexibility contributes to its excellent elastomeric properties, enabling it to deform and recover its shape, which is crucial for sealing and cushioning applications. The hydroxyl end-groups in RTV 107 are particularly important as they allow for cross-linking reactions, enabling the material to cure into a solid, resilient rubber at room temperature.
