RAW MATERIALS AND APPLICATIONS Use of Plasticizers made of renewable Raw Materials in multiphase Blend Systems

By way of comparison to the mineral oils conventionally used (TDAE and MES), chemically modified vegetable oils were employed as plasticizers in NR and s-SBR and as compatibilizers in the blend system. 

Plasticizers are low-viscosity substances. They interact with the rubber to which they are admixed to influence properties like ductility, processability and low-tem perature flexibility.[1] A reduction in viscosity during the blending process makes it possible to save energy and optimize filler distribution in the rubber compound.[2] Plasticizers also have an impact on rubber polarity, allowing for improved blend miscibility. This means that they can be used as compatibilizers.
