High-temperature silicones

High-temperature silicones are special sealing compounds designed for reliable sealing of joints exposed to extreme temperatures, mechanical stress, moisture, oils, fuels, and other operating fluids. Thanks to their high flexibility and excellent adhesion, they create a permanently elastic joint that resists aging, cracking, and long-term loads.

They are ideal for use in the automotive industry, mechanical engineering, heating, construction, and general home maintenance. High-temperature silicone can be used for sealing engines, gearboxes, water pumps, oil pans, heating devices, chimneys, ventilation systems, ovens, fireplaces, and other equipment exposed to high temperatures.

Our range includes high-temperature silicones in various colors and packaging sizes for both professional and home use. Selected products resist temperatures up to +380 °C, are resistant to oils, greases, fuels, water, and UV radiation, and can serve as a reliable replacement for conventional gaskets.

Advantages of high-temperature silicones

  • Resistance to high and low temperatures
  • Permanently flexible and strong sealing joint
  • Excellent adhesion to various materials
  • Resistance to oils, greases, fuels, and water
