| Description | High-temperature rubber strips, also known as high-temperature rubber gaskets or heat-resistant rubber gaskets, are made of silicone and offer excellent heat resistance, flexibility, and chemical resistance. It's the go-to choice for most high-temperature applications. Even at high temperatures, silicone retains flexibility, ensuring proper sealing and performance. The heat-resistant silicone seal strip can withstand continuous exposure to temperatures ranging from -60°C (-76°F) up to +260°C (+500°F). This wide temperature range makes it suitable for sealing around fireplaces, ovens, furnaces, and other high-heat applications in the home. We are a professional heat-temperature silicone seal strip manufacturer in China. If you need to withstand higher temperatures or thermal or fire resistance, we can custom special-grade silicone compounds for your project. Backed adhesive is available. |
