Technical Grade NBR Rubber Sheet

Technical Grade NBR (Nitrile) rubber sheet is a synthetic material widely used in various applications, owing to its excellent resistance to most petroleum-based fluids, oils and greases.

It offers moderate mechanical properties and satisfactory resistance to aromatic hydrocarbons, but is not suitable for use with ketones.

Nitrile rubber sheets are extensively applied in the automotive industry

Product Features

• Excellent Oil Resistance: Effectively resistant to petroleum oils, lubricants and vegetable oils.

• Stable Physical Properties: Features good heat resistance, wear resistance and airtightness for diverse working conditions.

• Long Lifespan: Great anti-aging capability to ensure prolonged service life.

• High Chemical Stability: Fine chemical resistance and easy processability for further fabrication.

• Premium Mechanical Performance: Medium hardness with high tensile strength to resist deformation and fracture.

Typical applications include:

• petroleum chemical

• automobile manufacturing

• food processing

• medical equipment and other industries

Our customers commonly use it to manufacture a wide range of oil-resistant molded products, including O-rings, oil seals, oil cups, diaphragms, valves, hoses and other sealing parts. It is also applied in the production of rubber sheets and wear-resistant components.

From raw materials to finished products, We do it all.

As a professional rubber sheet manufacturer with more than 15 years of industry experience, we have accumulated rich technical knowledge and extensive production expertise in the development and manufacturing of NBR rubber sheets. We are fully capable of satisfying diverse customer demands in terms of the scale of our production facilities, the density specifications, and the hardness ranges of our products. In our modern production base, we implement a complete and standardized manufacturing process, covering core procedures such as rubber compounding, high-precision calendering, professional vulcanization, and strict quality testing. Every step is carried out under standardized management to ensure stable performance, reliable quality and consistent specifications of our NBR rubber sheets.

Our strong production capacity is supported by a complete and advanced production equipment system: 6 open mills, 6 internal mixers, 4 calendering machines, 10 drum vulcanizers and 5 flat vulcanizers. In particular, each drum vulcanizer is equipped with an automated length measurement system, which greatly improves production efficiency, dimensional accuracy and product consistency.

Ensuring Quality at Every Stage: Product Inspections

Our comprehensive product and manufacturing inspection services are designed to rigorously uphold the quality standards of NBR rubber sheets throughout every stage of your manufacturing process. By implementing systematic inspections, we help you maintain consistent performance, reliability, and compliance with industry and customer requirements. Our professional inspectors conduct thorough verifications to confirm that all rubber sheet specifications are strictly met. These key parameters include tensile strength, elongation rate, vulcanization time, hardness, color consistency, and dimensional accuracy. Every critical characteristic is checked and documented to ensure the final product aligns with your predefined standards. 

To achieve full-process quality control, our inspections cover the entire production lifecycle, from initial manufacturing to final shipment. This includes the initial production check to validate setup and early-stage quality, in-process inspections to monitor ongoing production stability, container loading inspections to safeguard product integrity during packaging, pre-shipment inspections to confirm readiness for delivery, and continuous production monitoring to identify and resolve issues in real time. Through this end-to-end inspection system, we help you minimize defects, improve production efficiency, and deliver high-quality NBR rubber sheets that meet both your expectations and market demands.

Package: Focusing on efficiency & performance

To ensure the NBR rubber sheets remain in perfect condition during storage and transportation, we have implemented a complete and reliable packaging system. Each roll or sheet is first covered with a protective plastic film to prevent scratches, dust, moisture, and contamination. The rubber sheets are then neatly arranged on sturdy, fumigation‑free plywood pallets that meet international export standards. To enhance stability and avoid shifting during transit, we use high‑strength packing straps to securely fasten the entire load. Protective corner guards and rubber pads are installed at all potential contact points to avoid pressure marks, deformation, or damage caused by friction or strapping. We also use waterproof, wear‑resistant labels that clearly show product specifications, batch number, thickness, size, and quantity for easy identification.

For overseas shipments, the entire pallet can be covered with stretch film or waterproof shrink film for extra protection against humidity and rain. With these standardized packaging measures, we ensure that our NBR rubber sheets arrive clean, undamaged, and ready for use at your facility.
