Types of Fiber Seal Sheet

Non-asbestos Rubber Sheet

Non-asbestos rubber sheets are compressed materials used for gaskets and seals, offering a safe alternative to asbestos sheets. They are made from a combination of synthetic and natural materials, including fibrous materials like aramid fibers and glass fiber, and binder materials like nitrile rubber and neoprene. These sheets are designed to provide sealing and sealing-like functionality in various applications.

Asbestos Rubber Sheet

Asbestos rubber sheets are made of asbestos Fibre, rubber and heat-resisting packing material, compressing it to thick paper. Used for the equipment in water, steam, etc. And used as sealing material in the joints of the pipeline. When in use, gaskets of various shapes and sizes are generally punched as required.

Features of Fiber Seal Sheet

Corrosion resistance

Asbestos rubber sheets resist corrosion. You can use them for a long time in acidic environments without damage. This is crucial for dye manufacturers. It reduces downtime and maintenance from acid leaks.

High sealing performance

Asbestos rubber sheets can seal pipes and prevent acid leaks. They are key to the smooth operation of the production process.

Wear resistance

The textile industry's production process involves high friction and wear. Acid-resistant asbestos rubber sheets can withstand these pressures and remain stable.

Heat resistance

Some textile processes must high temperatures. Acid-resistant asbestos rubber sheets can perform well under such conditions.
