Features of Platinum Cured Silicone

  • Purity: The platinum-catalyzed cure system in platinum Cured O-rings, gaskets, and custom parts eliminates byproducts like volatile organic acids, making it safer for medical and food applications.

  • Enhanced Mechanical Properties: Platinum Cured O-rings, gaskets, and custom parts offer better tensile strength, elongation, tear strength, and compression set compared to peroxide cured silicone.

  • Temperature Resistance: Platinum Cured O-rings, gaskets, and custom parts are capable of withstanding both high and low temperature extremes while maintaining the materials elasticity and mechanical properties.

  • Transparency and Aesthetics: Platinum Cured O-rings, gaskets, and custom parts can have a clear to translucent appearance, which is beneficial for applications requiring visual monitoring or aesthetic appeal.

  • Biocompatibility: Platinum Cured O-rings, gaskets, and custom parts meet stringent standards for biocompatibility, making the material suitable for surgical and other medical applications.

Limitations of Platinum Cured Silicone

  • Cost: The use of platinum as a catalyst makes it more expensive than other curing methods.

  • Sensitivity to Contamination: Can be inhibited by certain materials and chemicals, which can interfere with the curing process.

  • Limited Adhesion: Generally exhibits lower adhesion properties to other materials without surface treatment or the use of adhesion promoters.
