Non-asbestos gasket materials are alternative materials used in place of traditional asbestos-based gaskets, which were commonly used in various industrial applications. Asbestos has been linked to serious health risks, including lung diseases and cancer, leading to its gradual phasing out and replacement with safer alternatives. Here are some common non-asbestos gasket materials:
Aramid Fiber: Aramid fibers, such as Kevlar, offer excellent resistance to heat, chemicals, and abrasion. They are often combined with other materials, like rubber or elastomers, to form non-asbestos gaskets.
Synthetic Fiber: Various synthetic fibers, such as glass fibers and carbon fibers, are used as non-asbestos gasket materials. They provide good resistance to temperature, pressure, and chemicals.
Graphite: Graphite is a popular choice for non-asbestos gaskets due to its excellent thermal conductivity and chemical resistance. It can be reinforced with other materials to enhance its sealing properties.
PTFE (Polytetrafluoroethylene): PTFE, commonly known as Teflon, is highly resistant to chemicals, heat, and electricity. It is used in gaskets as a non-asbestos material due to its low friction and non-reactivity.
Mica: Mica is a naturally occurring mineral that can be used as a non-asbestos gasket material. It offers good electrical insulation and high-temperature resistance.
Elastomers: Various elastomeric materials, including nitrile rubber, silicone rubber, and EPDM (ethylene propylene diene monomer), are used as non-asbestos gasket materials. They provide flexibility, good sealing properties, and resistance to chemicals and high temperatures.
Expanded PTFE: Expanded PTFE, also known as ePTFE or goretex, is a porous form of PTFE that is used as a non-asbestos gasket material. It offers excellent sealing capabilities and is suitable for a wide range of applications.
It's worth noting that the selection of industrial gasket material depends on the specific requirements of the application, such as temperature, pressure, chemical compatibility, and sealing performance. Different industries and applications may have specific standards and regulations regarding gasket materials, so it's essential to consult relevant guidelines and leading gasket manufacturer in India like Superlite Jointings Pvt. Ltd. when choosing non-asbestos gaskets for specific applications.
Use of Non-Asbestos Gasket in Industries
Non-asbestos gaskets are widely used in various industries as a safer alternative to traditional asbestos gaskets. They offer similar sealing capabilities while eliminating the health risks associated with asbestos exposure. Here are some industries where non-asbestos gaskets find application:
