STUDY OF THE SWELLING CHARACTERISTICS OF ELASTOMERS AS NEW CARS ARE BEING DEWAXED

New cars have a layer of wax to protect their paintwork. Before being delivered to the customer, the wax is removed in dewaxing plants with hot water and hydrocarbon additives, or with high pressure equipment. During this process it was observed that an acceptable degree of swelling occasionally occurred in the plastic components. Deutsche Exxon Chemical GmbH has developed an apparatus with which the critical parameters of the dewaxing process may be varied. This method permits the evaluation of different dewaxing agents as regards their effect in swelling elastomers. It is, however, also suitable for demonstrating serious deviations in the formulation of the elastomer mixture.
