The future oil fields: Defoamer based on renewable raw materials

Request brochure

26/2009 - 2009

Repeatedly increasing crude oil prices make the demand for renewable raw materials more urgent.

A more restrictive waste water legislation requires auxiliaries that are more easily biodegradable.

The market requirements for products which bear the ecological notion in mind made the RUDOLF GROUP expand its product range by a further defoamer based on rape seed oil.

®RUSTOL ARC is a silicone and mineral-oil-free defoamer based on renewable raw materials. Rape seed oil is the defoaming substance, which has grown on the fields of the administrative district Bad Tölz-Wolfratshausen, the region where RUDOLF GmbH is located.
