When comparing nitrile rubber rollers and fluoroelastomer rollers, the most critical distinction is their temperature resistance. Nitrile rubber rollers typically operate within a temperature range of -20°C to 100°C, whereas fluoroelastomer rollers can withstand long-term operating temperatures of 200°C to 250°C.

The English name for nitrile rubber is "Nitrile Butadiene Rubber," and its corresponding acronym is: NBR. Consequently, when industry professionals refer to "nitrile rubber rollers," "NBR rollers," or "NBR rubber rollers," all three terms effectively designate the exact same type of rubber roller material.

However, one thing is certain: NBR ages significantly faster when exposed to outdoor sunlight compared to indoor use. In environments with intense UV radiation, surface degradation can begin to manifest within just a few weeks.

The biggest Pro of nitrile rubber is its excellent oil resistance, especially to the following oily media: • Mineral oil • Lubricating oil • Hydraulic oil • Fuel oil (diesel, gasoline) • Animal and vegetable oils • Most hydrocarbon solvents The Con is that they are not suitable for cold environments.

NBR rollers can withstand temperatures of approximately 120°C in air and approximately 150°C in oil. This is determined by the combined characteristics of NBR's molecular structure, heat resistance, and oil resistance.

The hardness range of hydrogenated nitrile rubber rollers is usually between 50A and 90A. Specifically, hydrogenated nitrile rubber rollers with lower hardness (such as 50A-60A) are mainly used in situations requiring higher elasticity and better adaptability, while hydrogenated nitrile rubber rollers with higher hardness (such as 80A-90A) are suitable for environments with greater pressure and high temperature.

When burning, nitrile rubber will produce a very unique and pungent smell, which usually makes workers on the scene feel uncomfortable. Because nitrile rubber contains acrylonitrile, its combustion products include harmful substances such as hydrogen cyanide, so smelling a smell similar to "bitter almonds" or "burning plastic" is a significant sign to identify nitrile rubber.

Hydrogenated nitrile rubber rollers are made of hydrogenated nitrile rubber (HNBR). Hydrogenated nitrile rubber is obtained by hydrogenating nitrile rubber, which greatly improves the rubber's heat resistance, ozone resistance and chemical corrosion resistance.

Nitrile Rubber (NBR) is a synthetic rubber copolymerized by acrylonitrile (ACN) and butadiene (BD) monomers. The application areas of Nitrile Rubber Roller include: printing industry, textile industry, papermaking industry, automobile manufacturing industry, etc.
