NINGBO BODI SEALS CO.,LTD EXPORTED THE VITON ORING KITS TO USA
With the development of industry, fluorine rubber O-rings are widely used in automobiles, electronics, aerospace, ships, and other work environments that require high precision, high temperature resistance, high wear resistance, and harsh conditions. With the development of industry, fluorine rubber materials are also constantly improving and innovating.
Fluoro Carbon Rubber is a type of rubber with fluorine in its molecule, which varies depending on the fluorine content (i.e. monomer structure). The commonly used hexafluoride fluororubber was first listed by DuPont under the trade name “Viton”. High temperature resistance is superior to silicone rubber, with excellent chemical resistance, resistance to most oils and solvents (excluding ketones and esters), weather resistance, and ozone resistance; Cold resistance is relatively poor, and the general temperature range for use is -20~250 ℃. Special formula can withstand low temperatures up to -40 ℃.
Advantages:
·Can withstand heat up to 250 ℃
·It has resistance to most oils and solvents, especially all acids, aliphatic hydrocarbons, aromatic hydrocarbons, and animal and vegetable oils
Disadvantages:
·It is not recommended to use in ketones, low molecular weight esters, and mixtures containing nitrate· Cars, locomotives, diesel engines, and fuel systems.
Applicable scope:
·Seals for chemical plants.
Perfluorinated rubber FFPM
Advantages:
·Optimal heat resistance characteristics
·Excellent chemical resistance
·Low Outgassing Characteristics
·Excellent anti Plasma properties
Disadvantages:
·Poor low-temperature resistance
·High raw material prices
·High production difficulty
Applicable scope:
·The perfluorinated series of products are widely used in the semiconductor and information related industries, including PVC, CVD, etching processes, and various high vacuum sealing processes in thin film manufacturing.
Silicone fluorine rubber
FLS:
Fluorinated Silicone Rubber is a type of silicone rubber that has undergone fluorination treatment, and its general properties combine the advantages of both fluororubber and silicone rubber; It has excellent oil resistance, solvent resistance, fuel oil resistance, and high and low temperature resistance, and is generally used at temperatures ranging from -50 to 200 ℃.
Advantages:
·Suitable for special purposes, such as requiring resistance to the erosion of oxygen-containing chemicals, solvents containing aromatic hydrogen, and solvents containing chlorine.
Disadvantages:
·It is not recommended to be exposed to brake oil, ketones, and callose solutions on spacecraft components.
Perfluoroether Rubber Editing Broadcast
Perfluoroether rubber is composed of TFE (main chain), PMVE (branch chain), and bridging part. It not only has excellent high-temperature resistance and chemical corrosion resistance like PTFE (can withstand the corrosion of over 1600 chemicals), but also has the elasticity of rubber. Its compression deformation rate at 300 ℃ is only below 50%. The working temperature range of ordinary perfluorinated rubber is between -25 ℃ to+240 ℃, and Kalrez7075 can withstand high temperatures up to 327 ℃. Even when exposed to a constant temperature of 316 ℃ or intermittent high temperature environments such as 343 ℃, Kalrez production will not experience hardening and embrittlement that can cause seal failure. Kalrez can still maintain its elastic and rebound properties in direct contact with corrosive fluids. In fact, Kalrez’s thermal stability often exceeds those of the fluid itself. Perfluorinated rubber also has excellent airtightness (vacuum resistance up to 1.33X10-7-1.33X10-8pa), high cleanliness, and ionization resistance, which are widely used in the semiconductor industry.
