Non-Asbestos Gaskets

Non-asbestos gaskets provide a safe and effective sealing solution for various industrial applications. Made from advanced materials such as PTFE, graphite, and nitrile, these gaskets are a reliable replacement for traditional asbestos gaskets, which have been banned due to their harmful environmental impact.

Non-asbestos gaskets deliver high-performance sealing without the health risks associated with asbestos exposure in automotive, marine, power generation, and oil and gas industries.

These gaskets boast exceptional resistance to heat, chemicals, and extreme temperatures, making them ideal for applications involving natural gas, water, and petroleum products.

What Are Non-Asbestos Gaskets?

Non-asbestos gasket materials combine rubber with organic and inorganic non-asbestos fibers, namely fiberglass or aramid fibers. This material combination allows for flexibility in various mechanical specifications.

Key features of non-asbestos materials include outstanding heat resistance, temperature stability, and chemical resistance. Although they may have a higher initial cost than asbestos gaskets, different types of non-asbestos materials are available, allowing you to choose the best option based on your specific requirements.

Manufactured from environmentally friendly carbon and organic materials, non-asbestos gaskets are increasingly favored by industries prioritizing safety and sustainability. Their durability translates to long-term cost savings, making them a wise investment for businesses.

Industries such as power generation, chemical processing, marine applications, and automotive are recognizing the importance of environmental safety and reliability, making non-asbestos gaskets the optimal sealing solution.

Non Asbestos Gaskets Features & Benefits

Non-asbestos gaskets offer a range of benefits and features that enhance performance beyond mere temperature resistance.

  • Chemical Resistance: Made from advanced materials such as aramid fibers, nitrile, PTFE, and graphite, non-asbestos gaskets can tolerate various chemicals. This capability helps maintain sealing performance while significantly reducing the risk of leaks and contamination.
  • Heat Tolerance: Non-asbestos gaskets made from materials like graphite and aramid fibers can endure extreme temperatures ranging from -328°F to 932°C, making them ideal for industries that operate under high-temperature conditions.
  • Durability: Designed to resist wear and deformation, non-asbestos gaskets ensure a longer lifespan. This durability cuts operational costs and minimizes the need for frequent replacements, making them a cost-effective solution for various industries.

Non-Asbestos Gaskets Manufacturing Process:

Non-asbestos gasket materials are crafted from a variety of substances to suit different applications across a wide range of industries. The manufacturing process begins with the selection of materials, which involves mixing chosen fibers with fillers or binders.

Once the materials are selected and formed into sheets, they are cut using various techniques. Die-cutting is the most common method, where the material is cut into the required shapes. This technique is ideal for producing large quantities of gaskets with consistent dimensions.

Another method is laser cutting, which employs laser technology to achieve precise shapes from the gasket sheets. This technique is particularly well-suited for custom non-asbestos gaskets featuring intricate designs and complex geometries.
