High-Temperature Gasket (300°C)

The high-temperature gasket is an advanced sealing solution crafted from reinforced thermoplastic elastomers, designed specifically to address the needs of high-pressure environments. This material is sourced to exceed standard specifications, providing enhanced durability compared to typical versions found in the market. Its unique formulation allows this gasket to maintain its integrity and performance when subjected to the rigors of demanding applications, effectively distinguishing it from generic products in terms of resilience and reliability in physical form and application.

Composed of a blend of thermoplastic elastomers and fibers, this gasket is meticulously engineered to deliver superior mechanical strength and thermal stability. The incorporation of reinforcing fibers enhances its ability to withstand mechanical stress and deformation, ensuring a dependable seal across various industrial applications. This composite structure not only supports effective pressure sealing but also contributes to improved operational efficiency by minimizing the risk of leaks and failures inherent in high-stress environments.

Featuring a temperature rating of up to 300°C, a density of 1.2 g/cm³, and a low thermal conductivity of 0.15 W/m·K, this gasket operates effectively under extreme conditions. The specified density ensures reliable sealing performance while accommodating thermal expansion and contraction, essential in high-temperature machinery such as turbines and heat exchangers. These attributes make it an excellent choice for maintaining operational integrity, ultimately leading to reduced downtime and improved overall system efficiency.

Supplied in various formats, including rolls and pre-cut sheets, this gasket can be tailored to suit specific project needs. Customers should verify dimensions and desired quantities prior to ordering to ensure compatibility with their operational requirements. Zenco Systems Ltd maintains efficient supply logistics in Nairobi, facilitating prompt fulfillment for projects across East Africa, thus ensuring availability when it's needed most.

High-temperature gasket is built from reinforced thermoplastic elastomers and fibres, rated to a comparatively moderate 300°C but backed by a high ≥25 MPa compressive strength — it's positioned for high-pressure sealing duty rather than the extreme-heat furnace and kiln zones that call for ceramic fibre or refractory brick. Maintenance teams specify it for boiler sealing, furnace door gaskets, heat-exchanger sealing, steam pipe insulation, turbine and compressor packaging, industrial oven sealing, heating-element insulation, pressure-vessel gaskets, automotive exhaust sealing, chemical reactor gaskets, gas turbine sealing, and power-generation equipment seals — spanning cement, food processing, oil and gas, chemical manufacturing, and power-generation plants. It's also known under generic descriptive names — heat-resistant gasket, thermal insulation gasket, or PTFE gasket — all referring to reinforced elastomer gaskets in this class. It's supplied in rolls of 25m or sheet gaskets boxed in packs of 10, with custom-sized gaskets manufactured to request and various thickness increments up to 10mm available, packed on pallets for straightforward handling on site. Because its 300°C rating is well below the 1000°C-plus range of Zenco's ceramic and refractory products, confirm actual operating temperature before ordering — this is the correct choice for pressure vessels, pumps, and moderate-heat process equipment, tested to ASTM F104, not for furnace hot-face zones; where equipment cycles above 1000°C, our high-temperature textile or gasket-tape lines are the better fit. Install on clean, smooth surfaces using appropriate sealing techniques, since surface contamination is the most common cause of early gasket failure under pressure.
