What is a non-asbestos gasket?
Non-asbestos gasket sheets are made using organic fibers, aramid fibers, NBR and mineral fibers. These can be used for application where water or oil resistance is required. Generally, non-asbestos gasket sheets are used in low-pressure apparatus, transformers, and compressors.
What will replace asbestos gaskets?
Manufacturers found that other compressed, resilient fibers such as Kevlar and graphite were a safe and effective replacement to asbestos gaskets. Two of the most common brands for non-asbestos gaskets, ones you’ll often see on the shop floor of Breiner Non-Metallics, are Thermoseal (Klinger) and Garlock.
What material can I make a gasket with?
Because it is readily available, and has such a wide range of properties, silicone is the most commonly used material for FIP gasket production.
What is non asbestos gasket made of?
Non-Asbestos Gasket Materials Non-asbestos fibres include aramid, Kevlar and fibreglass. Aramid is often used for its excellent heat resistance and strength. The natural material is up to five times stronger than steel and twice the strength of glass fibre or nylon.
What is the difference between asbestos and non asbestos?
Asbestos are used in gasket because it can with stand high pressure ,High Temperature&its chemically inert in nature. Non asbestos gasket are made from man made fiber like carbon fiber, aramid fiber, synthetic fiber with NBR binder which insure pressure resistance, temperature resistance, chemical resistance.
What are fiber gaskets made of?
Some fibre gaskets are made from cellulose, which can be further impregnated with rubber, insulating fibre, synthetic fibre, or vulcanized fibre. Others, however, can be made from either vegetable fibre or aramid.
What are compressed non-asbestos gaskets?
These compressed non-asbestos gaskets provide excellent ability to seal, torque retention, and heat resistance that eliminates the need for asbestos. Gaskets manufactured from compressed non-asbestos materials are designed to perform in applications involving, air, water, steam, oils, acids and general chemicals.
What is the best non-asbestos gasket substitute?
The first company to come out with a quality non-asbestos substitute and to market it well was Garlock. At the time Garlock was the number two seller of compressed asbestos gasket material (number 3 was Durabla Manufacturing).
Is asbestos in a rubber gasket dangerous?
The asbestos in asbestos gasket material was embedded in the rubber it was blended with so, unless you took a grinder to the material to separate the asbestos out and then breathed in the asbestos (which could be avoided by oiling or wetting the material first), it was not going to hurt you.
What are compressed gaskets made of?
Durlon ® compressed gaskets are advanced in both quality and performance. The compressed sheets are made from unique ingredients and advanced proprietary manufacturing processes. They are high-density products containing the most homogenous combination of minerals, synthetic fibers, and elastomers available.
