Silicone Seals & Gaskets | High Temperature Resistant Silicone Rubber Sealing Components
What Are Silicone Seals and Gaskets?
Silicone seals and gaskets are elastic sealing accessories made of food-grade or industrial-grade silicone rubber. These soft rubber components are designed for gap filling, waterproof sealing, dust prevention, vibration damping and electrical insulation. Compared with ordinary rubber parts, silicone sealing products perform stably in extreme temperature environments and possess stronger chemical corrosion resistance. JRS supplies both standard silicone gaskets and fully customized silicone sealing parts with personalized sizes, shapes and hardness.
Core Features of JRS Silicone Seals & Gaskets
● Wide Temperature Resistance: Stable performance from -50℃ to +230℃, suitable for high-temperature and low-temperature working scenarios.
● Excellent Sealing Performance: High elasticity and compression resistance, effectively prevent water, dust, oil and air leakage.
● Durable & Anti-Aging: Resist ultraviolet rays, oxidation and chemical corrosion, long service life without deformation.
● Insulation & Shock Absorption: Good electrical insulation and buffer damping effect for electronic equipment protection.
● Multiple Material Grades: Industrial grade, food grade, medical grade silicone optional for different industries.
● Custom Molded Shapes: Support irregular, hollow, circular, square and special-shaped silicone gaskets.
