NBR Rubber Sheets/pads

NBR rubber sheets/pads are widely used in many industries due to their good oil resistance, wear resistance and mechanical properties.

Oil resistance and chemical resistance: NBR rubber has excellent oil resistance to petroleum products such as mineral oil, lubricating oil, diesel, gasoline, etc., so it is widely used in seals and gaskets in the automotive, mechanical equipment and petrochemical industries. In addition, NBR also has good corrosion resistance to some chemicals such as weak acids and weak bases.

Good mechanical properties: NBR rubber has good tensile strength, tear resistance and wear resistance, and is suitable for mechanical equipment operating under high pressure and high load environments, which can effectively reduce equipment wear.

Wide temperature adaptability range: NBR rubber can maintain stable physical properties in the temperature range of -40°C to 120°C, and is suitable for a variety of industrial environments, especially under high or low temperature working conditions such as automobiles and hydraulic equipment.

Excellent sealing performance: Due to the flexibility and elasticity of NBR rubber, it can fit well with the mating surface to form an efficient sealing effect, and is widely used in seals, gaskets, O-rings and other components of hydraulic and pneumatic systems.

DESCRIPTION

1. Material Introduction

NBR (nitrile rubber), also known as hydrogenated nitrile rubber, is a synthetic rubber polymerized from butadiene and acrylonitrile monomers. It has good oil resistance, wear resistance, aging resistance and good mechanical properties. NBR rubber is widely used in fields with high oil resistance requirements, such as the automotive, aviation and petrochemical industries.

2. Size specifications and customization

Common thickness: The common thickness of NBR rubber sheets/pads ranges from 0.5mm to 50mm, which can be customized according to needs.

Width and length: The standard size is usually 1000mm×1000mm, 1200mm×1200mm, etc., but it can be customized and cut according to customer requirements.

Customization options: Rubber sheets with different hardness, color, and surface treatment (such as smooth or non-slip surface) can be provided according to different application requirements.

3. Physical properties

Tensile strength: The tensile strength of NBR rubber is usually between 10-20MPa, which can withstand a certain tensile load without breaking easily.

Hardness: The hardness of NBR rubber is usually 60-80 Shore A, which can be adjusted according to demand to meet the needs of different applications.

Compression set: The compression set of NBR rubber is relatively low, and it can still maintain good sealing performance under long-term pressure.

4. Processing technology

Molding: It is often used to produce large-sized NBR rubber sheets and is suitable for producing thicker sheets.

Cutting and stamping: Gaskets of various shapes and sizes can be customized according to customer needs through CNC machine tools, laser cutting or die stamping.

Extrusion molding: It is suitable for the production of standardized products such as O-rings and sealing rings.
