Non-asbestos Composite Gasket Sheet



Non-asbestos composite seal gasket sheet is made of non-asbestos beater sheet reinforced with tanged steel. The asbestos-free gasket sheet has an excellent performance in dilatability, sealing equality, high-temperature resistance, and long life, etc., Mainly applied in automobile farming machines, motorcycles, engineering, etc., it is always used in high-strength gaskets and cylinder gaskets, etc.



Area of Applications：



Non-asbestos Cylinder Head Facing (CHF) applications. Good for sealing all sorts of lubrication oils, fuels, and combustion engine-related mediums。



Characteristics：



Environmental friendly material, Elastomeric binders, with good corrosion resistance, heat insulation, and sound insulation properties.



Temperature Recommended≤ 350 ℃



Thickness：



1.0-2.0mm, Other thicknesses of composite gasket material can be supplied upon requested

Compressed Non Asbestos Gasket Material A compressed fiber gasket   is a type of sealing device that is made from  a mixture of synthetic fibers and fillers, bound together with a rubber binder, which does not contain asbestos. Asbestos was once commonly used in gaskets due to its heat and chemical resistance, but it has been largely phased out due to health concerns.   Compressed non-asbestos gaskets are a safer alternative to asbestos gaskets, as they do not have any health risks.   Features of Compressed Non Asbestos Gasket Compressed non-asbestos gaskets are made from a mixture of synthetic fibers and fillers, bound together with a rubber binder. This combination of materials gives the gasket its strength, flexibility, and resistance to heat and chemicals. ​ Here are some of their key features:   High Temperature Resistance These cnaf gaskets   can withstand high temperatures, making them suitable for applications in industries like automotive, petroche...

Non Asbestos Gasket Paper

图片
Non-asbestos beater paper  is a type of gasket material that is free from asbestos fibers.   Non-asbestos gasket paper for sale  is typically made from a combination of cellulose fibers, synthetic fibers (such as aramid or Kevlar), and fillers. These materials are bonded together using elastomers or a suitable resin binder.   Users should always refer to product specifications and guidelines provided by the manufacturer to ensure the optimal selection and performance of the non-asbestos gasket paper 2mm  for their particular needs.     The Manufacturing Process of fuel resistant gasket paper It's important to note that the specific details of the manufacturing process may vary depending on the manufacturer, the type of non-asbestos material being produced, and the desired properties of the final product. Each manufacturer may have their own proprietary methods and formulations to optimize the performance and characteristics of their non-asbestos gasket...
