The effective pre-expansion of the reactive mix (froth effect) is of special advantage to flexible polyurethane foam applications. Very small amounts of CO2 are particularly appropriate for this. Hennecke's CARBOMAT is a blowing agent metering unit for charging polyurethane components with CO2 in a batch process. The focus is on optimized cell structure combined with gross weight reduction. Apart from enjoying the advantageous effects on the property spectrum of the end product, users of the Carbomat will especially benefit from an extremely economical and ecological production process. Therefore, the investment pays off in a record time.
