Solid silicone is a premium-grade elastomer engineered for exceptional durability, flexibility, and resistance to extreme conditions. Composed of high-purity silicone polymers, this material delivers superior performance across a wide range of industrial, automotive, medical, and electronic applications.
Temperature Resilience - Withstands extreme temperatures from -60°C to +230°C without losing structural integrity.
Chemical & Fluid Resistance - Excellent resistance to oils, solvents, acids, and alkalis, ensuring long-term reliability in harsh environments.
Mechanical Strength & Flexibility - Maintains elasticity and tensile strength under repeated stress, making it ideal for dynamic sealing and cushioning applications.
UV, Ozone & Weather Resistance - Performs reliably outdoors, resisting degradation from sunlight, oxidation, and atmospheric exposure.
Smooth & Uniform Finish - Manufactured in continuous rolls or precision-cut sheets with consistent thickness for easy fabrication.
While foamed silicone offers lightweight, thermal insulation, and compressibility due to its porous structure, solid silicone excels in applications requiring dense, impermeable barriers, high tear resistance, and prolonged mechanical stability. Both variants retain silicone's inherent benefits-non-toxicity, electrical insulation, and biocompatibility-making them indispensable in demanding industries.
Whether used in gaskets, seals, medical devices, or industrial machinery, solid silicone provides a robust, long-lasting solution tailored for precision and performance. Available in multiple durometers and custom formulations, it meets the stringent requirements of modern engineering challenges.
Superior Sealing & Gasketing Performance - Ideal for creating high-performance seals, gaskets, and O-rings that resist leaks, pressure, and extreme environments.
Precision Die-Cutting & Fabrication - Easy to cut, stamp, or mold into custom shapes, enabling fast prototyping and cost-effective production of complex designs.
Exceptional Longevity - Engineered for a long service life with excellent resistance to wear, fatigue, and permanent deformation, even under continuous stress.
Low Compression Set (<10%) - Maintains its original shape and sealing force after repeated compression, ensuring reliable performance in dynamic applications.
UV & Ozone Resistant - Withstands prolonged exposure to sunlight, oxidation, and outdoor weathering without cracking or hardening.
Wide Temperature Range (-60°C to +230°C) - Performs reliably in both extreme cold and high-heat environments, making it suitable for automotive, aerospace, and industrial uses.
Chemical & Moisture Resistant - Resists oils, acids, solvents, and water, ensuring durability in harsh operating conditions.
Flame-Retardant Options Available - Meets industry safety standards (UL94, ROHS) for applications requiring fire resistance.
Versatile Applications - Perfect for seals, gaskets, insulators, and vibration dampers in industries like manufacturing, energy, and electronics.
Customizable Solutions - Available in varying hardness levels (Shore A), colors, and thicknesses to meet specific requirements.
Eco-Friendly & Non-Toxic - Complies with FDA, REACH, and other international regulations for food-grade and medical applications.
