Mediaplast PS-1 is a synthetic plasticizer based on polyalkylbenzene, which is mainly recommended for the use in elastomers with low to medium polarity, e.g. NR, IIR, BR, SBR, EP(D)M, but also CR, CM/CSM, EVA and PNR.

In non-polar compounds, compared to mineral oil plasticizers, extremely high dosages are possible without the danger of migration of the plasticizer.

Mediaplast PS-1 has non-staining properties, therefore even light or colored compounds can be produced. The product is free of sulfur and its derivate and has a high degree of saturation; therefore the produced rubber articles show excellent mechanical properties. Due to the low setting point of approx. -24 °C the finished products also have an extraordinary cold flexibility.

Mediaplast PS-1 does not contain any heavy metals or polycyclic ingredients worth mentioning. Therefore it is not considered hazardous.
