BASF Launches An Additive For Low-VOC PU Foam

Heat created during the fabrication of polyurethane foams can cause discoloration, loss of mechanical characteristics, and even fire concerns if the polyols, the key raw components, are not properly stabilised. While traditional anti-scorch packages rely on phenolic antioxidants in conjunction with aromatic amine stabilisers, they have substantial limitations such as unpleasant odour, toxicity issues, and excessive volatility.

Adding substances that stop scorching can greatly lower the damage done by exothermic reactions while making PUR foam.

To address this, BASF has introduced Irgastab PUR 71, a novel and advanced anti-scorch solution that not only complies with requirements but also performs very well. This high-quality solution is free of aromatic amine, successfully addressing the limits of traditional anti-scorch additives.

Irgastab PUR 71 effectively reduces emissions and reduces the potential danger to both humans and aquatic organisms. As a result, PUR foams emit significantly less of the volatile organic compounds (VOC) and condensable emissions (FOG) than they once did. Because of these features, air quality within car interiors may be considerably improved, giving the automotive sector a competitive advantage.

BASF is committed to boosting the sustainability of plastics across the whole polymer value chain with new solutions and offers from its plastic additives business through VALERAS. The VALERAS portfolio includes Irgastab PUR 71.
