Oil-resistant rubber sheets are an important type of rubber sheets, which can be roughly divided into three categories based on their different characteristics.
Type A oil-resistant rubber sheets, also known as general oil-resistant rubber sheets, are made by vulcanizing reground nitrile rubber with various fillers and auxiliary materials. They can be reinforced with fabrics or other textiles to enhance the physical and mechanical properties of the oil-resistant rubber sheets. Type A oil-resistant rubber sheets are characterized by moderate oil resistance and wear resistance, as well as good waterproofing, shock absorption, and anti-slip properties. They are primarily used in mechanical processing, manufacturing industries, automotive and shipbuilding, and chemical enterprises. They are mainly used for laying on floors and countertops to provide oil resistance, waterproofing, and anti-slip protection, preventing direct contact with the ground that could damage products and protecting the surface from damage caused by heavy objects.
The B-grade oil-resistant rubber sheet is made from 30~60% nitrile rubber compounded with styrene-butadiene rubber and filled with sulfur. It offers moderate pricing. The B-grade oil-resistant rubber sheet boasts good physical and mechanical properties, with moderate oil resistance; it features sealing, wear resistance, flexibility, and low compression deformation rate. It can be used as a sealing component in oil-based mediums (such as engine oil, hydraulic oil, lubricating oil, and vegetable oil). It is primarily suitable for industrial applications such as gasket processing, equipment linings, and sandblasting linings. It is also ideal for workbenches and floors that come into contact with fats and oils, requiring high wear resistance, and for long-term use in electronic product environments.
The C-grade oil-resistant rubber sheet is made by vulcanization with more than 70% nitrile rubber and fillers. The C-grade oil-resistant rubber sheet boasts excellent oil resistance and high temperature resistance, making it suitable for use in high-temperature oil mediums (such as engine oil, diesel, gasoline, and lubricating oil) up to 120 degrees Celsius. Since the oil-resistant sealing components are directly produced by sealing component manufacturers, only some non-standard large-size sealing components require the use of the C-grade oil-resistant rubber sheet, thus narrowing its application scope and making it relatively expensive. It is primarily used to manufacture high-oil-resistant gaskets for sealing purposes in oil tanks and oil pipelines.
