Performance
Wide Temperature Resistance: Operates reliably in temperatures ranging from -60°C to 230°C (special grades up to 260°C), suitable for high-heat and cryogenic applications.
Superior Lip Sealing Integrity: The dual-lip rectangular profile creates a robust, leak-proof seal against gases, liquids, and moisture, even under pressure fluctuations.
Chemical Compatibility: Resists water, steam, alcohols, and mild chemicals, making it ideal for food, medical, and general industrial use (not recommended for petroleum-based oils or strong solvents).
Low Compression Set: Exhibits minimal permanent deformation under sustained compression, ensuring consistent sealing performance over extended service life.
Electrical Insulation: Silicone is an excellent electrical insulator, making it ideal for sealing electronic enclosures and automotive wiring components.
Customizable Design: Available in custom shapes (rectangular, circular, oblong) and colors to meet specific application requirements.
Application
Automotive Industry: Used in valve covers, intake manifolds, and electrical control units (ECUs) to seal against moisture, dust, and high-temperature gases.
Food & Beverage Processing: Seals ovens, steamers, and storage tanks, meeting food-grade standards for safe contact with edible products.
Medical & Pharmaceutical Devices: Used in sterile equipment and lab instruments, leveraging silicone’s non-toxic and biocompatible properties.
Industrial Machinery: Seals pumps, valves, and HVAC systems, providing reliable performance in high-temperature and moisture-rich environments.
Electronics & Appliances: Seals electronic enclosures, ovens, and coffee machines, protecting internal components from dust and liquid ingress.
Outdoor & Marine Equipment: Resists weathering and UV radiation, making it suitable for sealing outdoor lighting and marine hardware.
