• If your equipment is in high-temperature, steam, outdoor, chemical, weather-sensitive, or ozone-laden environments → ✔ EPDM rubber rollers are better • If your equipment must be in prolonged contact with oils, greases, fuels, or high-friction conditions → ✔ NBR rubber rollers are better

Nitrile butadiene rubber is non-toxic, and NBR rubber rollers are also non-toxic products. Nitrile butadiene rubber (NBR) is an industrial synthetic rubber material copolymerized from acrylonitrile and butadiene, possessing excellent oil resistance, abrasion resistance, and mechanical stability.

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.
