Introduction: Non-asbestos sheet materials are engineered materials designed to replace asbestos-containing products, offering similar performance characteristics without the health risks associated with asbestos exposure. These materials are commonly used in gaskets, brake pads, insulation, and other applications where heat resistance and durability are required.
Key Characteristics and Materials:
Aramid fibers:
Aramid fibers like Kevlar are frequently used in non-asbestos sheets due to their high strength and heat resistance.
Synthetic rubber (NBR):
Nitrile rubber (NBR) is a common binder used to hold the fibers together, providing oil and fuel resistance.
Fillers:
Various fillers are added to enhance specific properties like heat resistance, compressibility, or chemical resistance.
Heat and Chemical Resistance:
Non-asbestos sheets are designed to withstand high temperatures and a range of chemicals, making them suitable for diverse industrial applications.
Sealability:
Many non-asbestos sheets offer excellent sealing properties, preventing leaks and ensuring proper functionality of equipment.
Product Applications:
Gaskets:
Non-asbestos sheets are widely used in creating gaskets for various applications, including engines, pumps, and pipelines.
Sealing Materials:
They serve as sealing materials in a variety of industrial environments, including oil and gas, chemical processing, and marine applications.
Automotive and Industrial Parts:
Non-asbestos sheets are used in the construction of components for automotive and general industrial equipment.
Heat Insulation:
They can be used as insulation materials in high-temperature environments.
