Silicone gaskets are widely used in applications where extreme temperatures, flexibility, and long-term reliability are required. One of the key advantages of silicone gasket material is its exceptionally wide temperature operating range, making it suitable for demanding industrial, commercial, and technical environments.

Silicone Gasket Temperature Range Explained

Standard high-quality silicone gasket material typically operates within a temperature range of:

• -60°C to +200°C (continuous use)
• Up to +230°C (short-term exposure, depending on grade)

This wide range allows silicone gaskets to maintain their elasticity, sealing performance, and dimensional stability in both very low and very high temperatures, where many other rubber materials would harden, crack, or degrade.

Performance at Low Temperatures

Unlike many elastomers, silicone remains flexible at extremely low temperatures. Even at sub-zero conditions, silicone gaskets retain their ability to compress and seal effectively, making them suitable for outdoor equipment, refrigeration systems, and cold-storage applications.

Additional Benefits of Silicone Gaskets

In addition to their excellent temperature resistance, silicone gaskets offer:

Long service life with minimal performance loss

Excellent resistance to ageing and UV exposure

Good chemical resistance

Non-toxic and food-safe options available

Precision-Cut Silicone Gaskets

At CSMADE, silicone gaskets are precision cut using high-accuracy CNC machines, ensuring tight tolerances and repeatable results. Silicone gasket material can be supplied in various thicknesses and cut to custom shapes, making it suitable for both standard and bespoke sealing applications.
