Low alcohols (glycols) excess:
The specially designed column enables us to operate with low glycol excess. This excess is in range of 2-3wt% in the reaction water (depending on resin recipe) while older processes apply excess of glycols of 5-6%. The benefit of reducing the amount of glycols in circulation is the reduction of the resin production cost, and waste water pollution.
Highly accurate control both of the time/temperature diagram of the reactor and of the difference in temperature between the reactor and the heating fluid obtains the best possible results from the resin and avoids the formation of by-products. The supplied laboratory equipment allows performing input (raw material), inter-phasing (production) and outputting (product) control.
Low raw material costs:
Based on raw material price changes, Technobell does vary the raw material composition for each type of UPRs to reach highest product performance parallel with lowest available raw material costs.
