Product Overview
Oil resisting asbestos rubber sheet (also known as oil resistant gasket sheet, oil-proof asbestos rubber sheet, or oil resistant sealing sheet) is a compressed fiber-reinforced elastomer sheet used for cutting industrial gaskets.
It is engineered for sealing applications involving oil-based media, where conventional rubber sheets may degrade or lose sealing integrity.
Key Features
- Good resistance to mineral oil, lubricants, and fuel exposure
- Stable sealing performance under static compression
- Suitable for gasket cutting and flange sealing
- Good mechanical strength and durability
- Easy to punch, cut, and fabricate into custom gasket shapes
- Cost-effective industrial sealing material
Applications
Oil resisting asbestos rubber sheet is commonly used in the following industries and equipment:
- Oil pipelines and petrochemical systems
- Automotive engines and transmission systems
- Industrial machinery sealing parts
- Pumps, valves, and compressors
- Flange gasket sealing in oil and fuel environments
- Mechanical equipment exposed to lubricating oils
Material Composition
This oil resistant gasket sheet is typically manufactured using a blend of reinforcing fibers and oil-resistant rubber binders, formed under compression and vulcanization.
Main components:
- Reinforcing fibers (asbestos fiber or equivalent industrial fiber structure depending on specification requirements)
- Oil-resistant rubber binder system
- Inorganic fillers for improved stability and sealing performance
Product Advantages
- Reliable sealing in oil and hydrocarbon environments
- Maintains integrity under compression load
- Suitable for long-term static sealing applications
- Compatible with various industrial flange standards
- Reduces leakage risk in oil system joints
- Adaptable for customized gasket production
