Mediaplast NB-4 is a special adipine acid plasticizer at an exceptionally reasonable price for the use in polar polymers like NBR, H- and XNBR, CM / CSM, CR, ECO, etc. Mediaplast NB-4 is, due to its relatively low volatility and also because of its extremely low setting point, suitable for heat-resistant as well as cold flexible rubber articles (see technical data). The production of rubber products with a cold flexibility lower than - 40 °C is possible, for example. Compared to mineral oil plasticizers as well as many ester plasticizers the compatibility within NBR compounds is much higher. In the contrary to more volatile and often more expensive ester plasticizers, Mediaplast NB-4 does not cause soiling on the molds.

If polymethacrylates come in contact with Mediaplast NB-4 containing compounds, they are not influenced negatively (test at 70 °C, 21 days). Due to the characteristic light color of Mediaplast NB-4, it can also be used for the production of light or colored rubber compounds. As the softening effect of Mediaplast NB-4 is especially high, the dosage should be reduced slightly, when comparing tests are run. This should also be considered when judging swellings in different media.
