Project details

VITON and HNBR O-rings are both sealing materials, but there are some differences in performance and application.

VITON is a fluorinated rubber with excellent high-temperature resistance, corrosion resistance, and chemical resistance. It can maintain good elasticity at high temperatures and is not easily deformed in various chemical environments. Therefore, VITON is mainly used in high-temperature and chemically corrosive environments, such as aerospace, petrochemical and other fields.

HNBR O-ring is a sealing element made of hydrogenated nitrile rubber, which has good oil resistance, high temperature resistance, chemical corrosion resistance, and ozone resistance. It can maintain good sealing performance in high temperatures and harsh environments, while also having good resistance to organic substances such as fuels and lubricants. Therefore, HNBR O-rings are mainly used in petroleum based oils and fuels, lubricants, aliphatic hydrocarbons, vegetable oils, silicone oils, and greases.

Overall, both VITON and HNBR O-rings are high-quality sealing materials, but there are certain differences in application scenarios. The specific choice of material needs to be determined based on actual usage needs and environmental conditions.
