NBR Material Seal Solutions — Bost Engineering Plastics

NBR Material Seal Solutions by Bost

Product Overview

Bost's NBR material seal line delivers engineered sealing solutions designed for demanding industrial, automotive and hydraulic applications. Using nitrile butadiene rubber (NBR), our seals offer excellent resistance to oils, fuels and lubricants while maintaining dimensional stability and long service life. Paired with Bost’s advanced engineering plastics and steel-plastic assemblies, these seals form durable, integrated components for modern equipment.

Key Properties & Performance

NBR material seals from Bost provide balanced performance: superior oil and fuel resistance, good abrasion resistance, low compression set and reliable performance in temperatures typically from -40°C to +120°C. Available in Shore A hardnesses from ~40 to 90, our seals can be tailored for static or dynamic sealing, low-friction sliding, or high-pressure applications. This optimized property set makes Bost NBR seals ideal where long-term reliability is critical.

Manufacturing & Customization

Bost combines deep R&D expertise with precision molding, extrusion and CNC machining to produce custom NBR material seals in a wide range of profiles, sizes and compound formulations. We excel at multi-material solutions—overmolding NBR to engineering plastic housings or bonding seals to steel—enabling integrated parts with enhanced toughness, flame retardancy and thermal conductivity when required.

Applications

Our NBR material seals are widely used in hydraulic systems, pumps, automotive fuel systems, compressors, industrial valves and green energy equipment. Where compatibility with oils, fuels and hydraulic fluids is required alongside high wear resistance and fatigue life, Bost NBR seals deliver reliable sealing performance that reduces downtime and maintenance costs.

Quality, Testing & Sustainability

Bost adheres to strict quality controls and testing standards (ASTM/ISO) throughout compound development and production. As a high-tech green energy engineering plastics manufacturer, we prioritize sustainable processes, low-emission materials and efficient production to support customers’ environmental goals while ensuring exceptional product quality.

FAQ:

What are the core advantages of Bost engineering plastics compared to ordinary plastics?

Bost engineering plastics feature ultra-high mechanical strength, high-temperature resistance (-50°C to 300°C), chemical corrosion resistance, and wear resistance. Compared to ordinary plastics, their service life is extended by 3 to 8 times, making them suitable for replacing metals in harsh environments.

What is the delivery lead time? Do you offer global logistics?

Standard products: 5–15 working days; custom modifications: 2–4 weeks. We support global air/sea freight and provide export customs clearance documents (including REACH/UL certifications).

How do I select the appropriate engineering plastic grade for my product?

Selection should be based on parameters such as load conditions (e.g., pressure/friction), temperature range, medium contact (e.g., oil/acid), and regulatory requirements (e.g., FDA/RoHS). Our engineers can provide free material selection consulting and sample testing.

What is the minimum order quantity (MOQ)? Do you support small-batch trial production?

The MOQ for standard products is ≥100kg. We support small-batch trial production (as low as 20kg) and provide mold testing reports and performance data feedback.

Can Bost customize modified plastics with special properties?

Yes! We offer modification services such as reinforcement, flame retardancy, conductivity, wear resistance, and UV resistance, for example:
• Adding carbon fiber to enhance stiffness
• Reducing the coefficient of friction through PTFE modification
• Customizing food-grade or medical-grade certified materials
