BASF launches new anti-scorch solution

Launched on December 12, the premium solution has been formulated without aromatic amine, addressing the limitations of conventional anti-scorch additives effectively.

According to Dr. Bettina Sobotka, head of Global Marketing and Development, Plastic Additives from BASF, Irgastab PUR 71 reaffirms BASF's commitment to innovation and partnership within the industry.

“We offer our customers a sustainable alternative to conventional solutions, empowering them to gain a significant advantage in the ever-changing global market,” said Sobotka.

The heat generated during the polyurethane foam manufacturing process can cause discolouration, loss of mechanical properties, and even fire hazards if the polyols, the main raw materials, are not properly stabilised.

While conventional anti-scorch packages rely on phenolic antioxidants combined with aromatic amine stabilisers, they come with significant drawbacks such as unpleasant odour, toxicity concerns, or high volatility.

The use of anti-scorch additives can greatly minimise degradation caused by exothermic reactions during the processing of PUR foam.

As Irgastab PUR 71 is formulated without aromatic amine, it effectively decreases emissions and lowers the potential harm to both humans and aquatic life. This leads to significantly reduced levels of volatile organic compounds and condensable emissions 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 for various industries. It enables lower emissions in compliance with the most stringent automotive industry specifications and improves the air quality of vehicle interiors.

It also 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 classification, allowing polyol producers to comply with environmental voluntary certifications and keep their anti-scorch recipe confidential.

For consumer goods, it enhances product quality by providing improved whiteness and resistance to colour change caused by gas fading and light-induced discolouration.

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.
