• Formulated without aromatic amine to promote a better environmental, health and safety profile
• Premium anti-scorch solution offers reduced emission levels and exceptional performance
• Sustainable alternative offers polyol and foam producers a competitive advantage

BASF presents Irgastab® PUR 71, an innovative and advanced anti-scorch solution that not only ensures adherence to regulations but also offers exceptional performance. This premium solution has been formulated without aromatic amine, effectively addressing the limitations of conventional anti-scorch additives. With its superior environmental, health, and safety profile, this solution meets the increasing regulatory pressure on substance classification and sustainability in the industry.

“Irgastab PUR 71 reaffirms BASF’s commitment to innovation and partnership with the industry: We offer our customers a sustainable alternative to conventional solutions, empowering them to gain a significant advantage in the everchanging global market,” said Dr. Bettina Sobotka, Head of Global Marketing and Development, Plastic Additives, BASF. “With a proven track record in additives, backed by our global team of experts dedicated to the development of the automotive and comfort industry, we strive to pioneer cutting-edge technologies and solutions that not only enhance performance, but also promote sustainability.”

In the manufacturing of polyurethane foams, the heat generated during the process can cause discoloration, loss of mechanical properties, and even fire hazards if the polyols, the main raw materials, are not properly stabilized. While conventional antiscorch packages rely on phenolic antioxidants combined with aromatic amine stabilizers, they come with significant drawbacks such as unpleasant odor, toxicity concerns, or high volatility.

The use of anti-scorch additives can greatly minimize degradation caused by exothermic reactions during the processing of PUR foam. Irgastab PUR 71, formulated without aromatic amine, effectively decreases emissions and lowers the potential harm to both humans and aquatic organisms. Consequently, this leads to significantly reduced levels of volatile organic compounds (VOC) and condensable emissions (FOG) released from PUR foams. Due to these properties, air quality within the interior of vehicles can be greatly improved, creating an advantage in the automotive industry.

Irgastab PUR 71 provides targeted application benefits in various industries. It enables lower emissions in compliance with the most stringent automotive industry specifications and improves the vehicle interior air quality. In the comfort sector, it offers state-of-the-art anti-scorch resistance to polyol as well as foam producers, preventing heat degradation during the foaming process. In addition, it has no Carcinogenic, Mutagenic and Reprotoxic (CMR) classification, allowing polyol producers to comply with environmental voluntary certifications and keep their antiscorch recipe confidential. For consumer goods, it enhances product quality by providing improved whiteness and resistance to color change caused by gas fading and light-induced discoloration.

Irgastab PUR 71 is part of the VALERAS® portfolio. With VALERAS, BASF is committed to increasing the sustainability of plastics along the entire polymer value chain with innovative solutions and offerings from its plastic additives business.
