Biesterfeld to supply Denka acrylate rubbers

Hamburg, Germany – Biesterfeld is expanding its partnership with Denka Co. Ltd by taking on the distribution of Denka ER acrylate rubbers with immediate effect, the German distributor has announced. 

The new agreement applies to the whole of Europe, excluding Spain and Turkey, Russia and Brazil, said a Biesterfeld press release, issued 14 Jan

With a fully saturated polymer chain, Denka ER elastomers are claimed to offer both “outstanding” heat stability at temperatures up to 190°C and very good resistance to oil. 

The polymer structure enables them to deliver superior resistance to cyclic heat and oil stresses compared with established acrylate rubbers, added Biesterfeld. 

Other features include good UV and ozone resistance, while the rubber materials are also said to offer low-temperature flexibility down to minus 35°C.

Primary applications include automotive charge-air or transmission-oil cooler hoses and engine gaskets, as well as industrial roll covers, seals and hoses.

“With the new distribution rights, we are expanding our range of special elastomers and adding acrylate rubbers to our catalogue,” said Jörn Thomsen, product manager specialty polymers, Biesterfeld Performance Rubber. 

“With particular emphasis on further developments in high-temperature stability [Denka ER] stresses the high technical expertise of the manufacturer," added Thomsen.
