TOP QUALITY RUBBER
By using rubber qualities such as EPDM and EPM, the deterioration process caused by the influence of high temperatures can be limited. These rubber qualities stay flexible for longer and have a service life of many years. Several Polysur® versions are fully resistant to oils and greases, both mineral and vegetable. Very high concentrations of NBR rubber are used in these rubber mixtures, which counteracts hardening, swelling and blistering.
