Product Description

Introduction of asbestos gasket

Asbestos gasket is a sealing material made of asbestos fiber and rubber as the main raw materials, supplemented by rubber compounding agents and fillers, through mixing, hot roll forming, vulcanization and other processes. This material is widely used in many industrial fields due to its excellent sealing performance and corrosion resistance.

Main raw materials

Asbestos fiber: provides good temperature resistance and mechanical strength.
Rubber: enhances elasticity and sealing.
Compounding agents and fillers: improve processing performance and physical properties.

Classification and application scenarios
Asbestos gaskets can be divided into many types according to their formula, process performance and use, and each type is suitable for different temperature and pressure conditions.

Ordinary asbestos rubber gasket
Suitable for most low temperature and low pressure requirements, mainly used for steam, hydraulic, gas, oil and non-corrosive media sealing.

Oil-resistant asbestos rubber gasket
It is made of high-quality asbestos fiber, oil-resistant fiber, filler, colorant, etc., and is widely used in pipelines and equipment in the petroleum and chemical industries.

High-pressure asbestos rubber gasket
It is suitable for sealing under high-pressure environments, such as the tank mouth, manhole, hand hole sealing of the reactor.

Medium-pressure asbestos rubber gasket
It is mainly used for sealing under medium pressure conditions and is suitable for a variety of industrial applications.

Technical parameters
Temperature range: +200°C to +450°C.
Pressure level: divided into low pressure, medium pressure and high pressure according to specific needs.
Advantages
Good sealing performance: can effectively prevent medium leakage.
Excellent corrosion resistance: suitable for sealing various chemical media.
High mechanical strength: the material is easy to cut and shape, and has strong adaptability
