Fluorocarbon elastomers have grown to major importance in the sealing industry. Due to its wide range of chemical compatibility, temperature range, low compression set, and excellent aging characteristics, fluorocarbon rubber is the most significant single elastomer developed in recent history. Fluorocarbon elastomers are highly fluorinated carbon-based polymers used in applications to resist harsh chemical and ozone attack.

• The working temperature range is considered to be -26°C to +205°/230°C (-15°F to +400°/440°F).
• For short working periods it will take even higher temperatures.
• Special compounds having improved chemical resistance are also available with new types always being developed in our own R&D centers.

Generally speaking, with increasing fluorine content, resistance to chemical attack is improved while low temperature characteristics are diminished. There are, however, specialty grade fluorocarbons that can provide high fluorine content with low temperature properties.

We have certificates :ISO 9001:2015 , ISO 14001:2015 ,ISO 45001:2018 , IATF , FDA, REACH, ROHS, SGS etc.
