The core difference between asbestos and non-asbestos gaskets is that Asbestos gasket contains asbestos, which is used as a reinforcing fibre whilst non-asbestos gaskets contains non-asbestos reinforcing fibres. Though Asbestos gaskets are high resistance to chemicals and heat, they also make it a harmful substance to work with. That’s why majority of gasket consumers now prefer non- asbestos gaskets that are equal to or better than asbestos gaskets. One type of fibre that is commonly used in manufacturing non-asbestos sheet is aramid fibre and is known for being around 2 to 9 times more durable than asbestos.
