What are non-asbestose gasket sheets

Non-asbestose gasket material is a fiber-reinforced sealing sheet developed as a safe and effective alternative to traditional asbestos-based gaskets. It consists of synthetic fibers, fillers and rubber binders, offering durability under pressure and temperature without the health risks associated with asbestos.

These gasket sheets are commonly used in industrial settings where reliable sealing performance is required under mechanical and thermal load.

When to use non-asbestos gasket material

Non-asbestos gasket material is used in applications involving elevated temperatures, pressure or aggressive media, especially where health and safety standards prohibit the use of asbestos-based products. It is particularly relevant in retrofit or maintenance scenarios.

This material is widely adopted in industries such as food processing, pharmaceuticals and petrochemicals, where compliance with environmental and occupational safety regulations is critical.

Applications of non-asbestos gasket sheets

Non-asbestos gasket sheets are used in flange connections, pumps, compressors, heat exchangers and piping systems. They are suitable for sealing steam, oil, water and gas.

Depending on the binder type (such as NBR, SBR or EPDM) and fiber composition, these sheets can be tailored to match specific temperature, pressure and chemical resistance requirements.

Non-asbestos gasket sheets specifications

Type: Non-asbestos compressed fibre gasket sheet (Doniflex-A)
Composition: Aramid/cellulose fibres with elastomer binder (typically NBR) and mineral fillers
Temperature Range: approx. −40 °C to +250 °C (short peaks higher, depending on application)
Pressure Range: medium to high (depends on flange design, bolt load and medium)
Resistance: water, steam, oils, fuels, mild chemicals

Doniflex-A is a general-purpose, non-asbestos fibre gasket material for industrial flange sealing. It offers good mechanical strength and reliable sealing performance in common utilities and process applications. Suitable for cutting flange gaskets, rings and custom shapes from sheet material.

Custom production

In addition to standard Non-asbestos gasket sheets, we can CNC cut custom shapes and dimensions to your drawing. Suitable for prototypes, small series and repeat production.
