NBR - Nitrile Rubber Sheet

NBR (Nitrile) rubber sheet is a synthetic elastomer well-suited for diverse uses. It features outstanding resistance to most petroleum liquids, oils and lubricants.

This material has decent mechanical performance and fair resistance to aromatic hydrocarbons, yet it cannot be used in contact with ketones.

Nitrile rubber sheets find broad application in the automotive sector.

Product Features

• Resistant to petroleum oils, lubricating oils and vegetable oils.

• Good heat resistance, wear resistance and airtightness.

• Suitable for permeable & ventilated environments.

• Excellent anti-aging performance, long service life.

Typical applications include:

• Petrochemical

• Automobile Manufacturing

• Food Processing

• Medical Devices and Other Fields

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.

We are a seasoned rubber sheet manufacturer with 15+ years of experience. We have profound expertise in the R&D and production of NBR rubber sheets, and can fully cater to your diverse demands for production capacity, density and hardness.

Equipped with modern facilities, we follow complete standardized procedures from rubber mixing, high-precision calendering and vulcanization to strict quality testing. Every production link is strictly managed to ensure stable performance, dependable quality and consistent product standards.

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.
