Fluoro Elastomer rubber or FKM is based on hexa-fluoropropylene vinyl-idene fluoride. The polymer has high resistance to heat with a temperature range of -40° C to + 250° C. It has also possesses a good flame resistance and is usually self-extinguishing. FKM’s have excellent resistance to oxygen, ozone and natural weathering and also have outstanding resistance to compression, especially at elevated temperatures. Its resistance to most solvents and chemicals give long service life as it has excellent resistance against hydrocarbons, aliphatic, aromatic and chlorinated chemicals and resistance to acids and alkalis including oxidants. However, they have poor performance against ethers, ketones and bases.
If required, we supply technical rubbers in the form of semi-finished or finished products. Most of the standard technical rubbers in our range are permanently in stock, so we can offer not only very short delivery or production times, but also the possibility of producing atypical variants from a single piece.
Delivery times: It mainly depends on the batch size and the complexity of products. Our standard delivery time is usually no more than one week of placing the order. Given our warehouse stock we are able to offer production on short notice in emergency situations.
