Silicone rubber stands out in the world of elastomers. With a wide thermal range, chemical resistance, flexibility, and biocompatibility, it has become a go-to material for modern manufacturing. Whether it's automotive seals, medical-grade components, or electronics insulation, silicone rubber is an irreplaceable material for high-performance, long-lasting products.

At Xiamen Jinshun Sealing Technology Co., Ltd., we specialize in custom silicone parts manufacturing, offering full-service ODM solutions for global partners. With years of material engineering expertise, we help brands bring their silicone product ideas to life.

What makes silicone rubber ideal for so many industries? Here's a breakdown of its standout features:

✅ Wide Temperature Resistance

Functions from -60°C to +250°C

Tolerates sudden thermal changes without cracking or deforming

Suitable for oven-safe, automotive, or high-voltage applications

✅ Non-Toxic and Safe

BPA-free, food-grade formulations available

Approved for baby products, kitchenware, and medical use

✅ Superior Electrical Insulation

High resistivity, stable across temperatures and frequencies

Used in high-voltage caps, electrical seals, and insulating films

✅ Weather, Ozone & UV Resistance

Perfect for outdoor gaskets and seals

Long-term durability without cracking, yellowing, or loss of strength

✅ Water, Oil, & Chemical Resistance

Performs reliably in harsh environments such as chemical plants and oil systems

Ideal for gaskets, seals, and vibration-damping components

✅ Flexible Yet Durable

Maintains elasticity over time

Available in soft-touch or high-strength formulations depending on need

✅ Thermal Conductivity (Optional)

Enhanced heat dissipation with thermal fillers

Used in photocopiers, heat pads, and LED modules

✅ Radiation Resistance

Phenyl-based silicone rubber resists radiation, used in nuclear-grade components

✅ Anti-Stick Surface

Low surface adhesion, ideal for molds and release layers

One of silicone rubber's defining features is its high heat tolerance. While most plastics deform at high temperatures, silicone remains stable until combustion begins.

Typical operational range: –60°C to +250°C

Thermal decomposition begins around: 300°C

Does not melt like conventional thermoplastics – instead, it degrades slowly over time

Silicone rubber softens with rising temperature, but maintains form and function far beyond other rubbers. This makes it ideal for industries requiring sustained heat exposure - such as automotive, aerospace, and electronics.

Understanding the different types of silicone rubber helps you select the right material for your specific application.

Each type is optimized for specific industries. For example, platinum-cured LSR is ideal for medical devices, while peroxide-cured SSR suits automotive gaskets.

Custom silicone parts are now used in nearly every sector due to their versatility and performance.

• Automotive: O-rings, engine seals, wire gaskets, vibration dampers
• Electronics: Keypads, cable insulation, connectors, EMI shielding
• Medical: Seals for devices, tubing, baby pacifiers, surgical components
• Household Products: Bakeware, bottle nipples, microwave-safe lids
• Aerospace: Fuel system gaskets, insulation layers, window seals
• Industrial Equipment: Chemical-resistant seals, thermal pads, custom sleeves

At Jinshun Sealing, we engineer each silicone part to match exact functional, dimensional, and regulatory requirements.
