Platinum Cured Silicone

Discover the Purity and Performance of Platinum Cured Silicone Rubber

For applications demanding the highest levels of cleanliness, biocompatibility, and performance, platinum cured silicone rubber stands apart. Unlike traditional peroxide-cured silicones, the platinum curing process utilises a platinum-based catalyst, resulting in an exceptionally pure elastomer with minimal by-products. This leads to a material with superior physical properties, excellent clarity, and an inert nature, making it the preferred choice for critical environments where extractables and leachables must be minimised. Our range of platinum cured silicone rubber products is manufactured to the highest standards, ensuring reliability and compliance for the most sensitive applications.

Key Features of Platinum Cured Silicone Rubber

Platinum cured silicone rubber offers a distinct advantage through its advanced curing mechanism, providing a range of superior characteristics.

• High Purity: The platinum curing process leaves virtually no volatile organic by-products, ensuring a very clean and inert material.
• Excellent Biocompatibility: Due to its high purity, platinum cured silicone is highly biocompatible, making it suitable for medical and pharmaceutical applications.
• Low Extractables and Leachables: The absence of peroxide by-products significantly reduces the risk of substances leaching from the silicone into contacted media.
• Superior Physical Properties: Generally exhibits higher tensile strength, elongation at break, and tear strength compared to peroxide-cured silicones, leading to enhanced durability and performance.
• Greater Clarity and Non-Yellowing: Typically results in a more translucent or clear material that does not yellow over time, which is beneficial for applications requiring visibility.
• Odourless and Tasteless: The clean curing process ensures the final product is free from residual odours and tastes.
• Wide Temperature Resistance: Maintains flexibility and integrity across a broad temperature range.
• Excellent Compression Set: Offers good resistance to permanent deformation under continuous pressure, ensuring reliable long-term sealing.
• Resistance to Sterilisation: Withstands various sterilisation methods, including autoclaving, gamma irradiation, and ethylene oxide, without significant degradation of properties.
