Name: HNBR For Automotive Synchronous Belt
Brand: DAWN
SKU: 241882896

Products Description

Ordinary nitrile rubber (NBR) has far from been able to satisfy the characteristics of oil resistance, heat resistance, high temperature resistance, high pressure resistance, and oxygen resistance of rubber parts for automobiles and oilfields under harsh conditions, and the price of fluoroelastomers is expensive. Therefore, Dawn polymer began to explore the improvement of NBR performance, and hydrogenated nitrile rubber (HNBR) was developed successfully to meet this new need and developed successfully.

Products advantage

High Heat Resistance

One of the most significant advantages of HNBR for automotive synchronous belts is its exceptional heat resistance. It can withstand temperatures up to 150°C, making it ideal for use in engines and other high-temperature environments. Its excellent thermal stability enables automotive synchronous belts to maintain their shape and function effectively, even under extreme heat and pressure.

Good Resistance to Ozone and Weathering

HNBR's excellent resistance to ozone, weathering, and UV radiation makes it a highly durable material for automotive synchronous belts. Ozone, which is often present in the air, can cause rubber materials to crack and degrade over time, reducing the lifespan of the synchronous belt. HNBR's superior resistance to ozone and weathering ensures that the synchronous belt can perform efficiently for an extended period.

Good Chemical Resistance

HNBR is also resistant to a wide range of chemicals, including oil, gasoline, and hydraulic fluids, making it particularly useful for automotive power transmission applications. These chemicals can corrode and damage regular rubber materials over time, but HNBR's exceptional chemical resistance properties ensure that the synchronous belt can maintain its integrity and perform effectively even in harsh chemical environments.

Good Compression Set Performance and Swelling Resistance

HNBR has excellent compression set performance and swelling resistance, making it ideal for automotive synchronous belts that require long-term reliability. Under compression, some rubber materials can lose their rebound properties over time, leading to permanent deformation. HNBR's high compression set performance ensures that the synchronous belt can maintain its original shape and function efficiently over time.

Good Wear Resistance

Finally, HNBR has superior wear resistance properties, making it ideal for automotive synchronous belts that undergo high levels of wear and tear. Its high abrasion resistance ensures that the synchronous belt can withstand continuous use and vibration without wearing down quickly, thereby increasing the lifespan of the component.
