SILICONE SEALS UP TO 300°C

High-Temperature Silicone Gaskets up to 300°C – Reliable Sealing from an Experienced Manufacturer

 

At Guma Pomorska, we specialize in the production of rubber, polyurethane, and silicone components designed to perform in the toughest industrial conditions. Among our key products are silicone gaskets resistant to temperatures up to 300°C – trusted wherever reliability and precision are essential.

Why silicone performs perfectly at high temperatures?

Silicone’s unique structure, based on strong silicon–oxygen bonds, gives it exceptional thermal stability. This allows our high-temperature silicone gaskets to maintain flexibility, elasticity, and sealing properties from –60°C to +300°C.
Even during long exposure to heat, they retain their shape and mechanical strength, ensuring durable and consistent sealing performance.

Applications of 300°C silicone gaskets

Our heat-resistant silicone gaskets are widely used across many industries, including:

• Household appliances – ovens, coffee machines, grills, and other high-temperature devices,

• Food and pharmaceutical production – where cleanliness and resistance to sterilization are essential,

• Laboratories and industrial equipment – exposed to continuous high-temperature operation,

• Automotive and machinery sectors – in areas exposed to heat but not directly to oils or fuels.

Advantages of high-temperature silicone gaskets

1. Excellent dimensional stability – retain their shape even under long exposure to heat.

2. Wide temperature range – perform reliably from extreme cold to intense heat.

3. Aging resistance – silicone remains elastic and stable over time.

4. Food-grade safety – the material can be certified for contact with food.

5. Custom manufacturing – available in various hardness levels, shapes, and colors tailored to specific projects.

Custom silicone gasket production

As a manufacturer of rubber and polyurethane products, Guma Pomorska provides custom-made silicone gaskets according to the customer’s drawings, samples, or technical specifications.
We use modern production technologies and high-quality silicone compounds to ensure precision, repeatability, and long service life — even under extreme temperature conditions.

Summary

Silicone gaskets resistant to 300°C offer exceptional durability and flexibility wherever sealing performance must remain stable under heat.
Choosing products from Guma Pomorska means choosing a trusted manufacturer with proven experience in producing rubber, polyurethane, and silicone components for demanding industrial applications.
