Anti-scorch solution without aromatic amine for enhanced performance and sustainability

BASF presents Irgastab PUR 71, an advanced anti-scorch solution that ensures adherence to regulations and offers exceptional performance. Formulated without aromatic anime, the premium solution effectively addresses the limitations of conventional anti-scorch additives.

In the manufacturing of polyurethane foams, the heat generated during the process can cause discoloration, loss of mechanical properties, and even fire hazards if polyols, the main raw materials, are not properly stabilized.

While conventional anti-scorch 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 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.

BASF developed an anti-scorch solution that is formulated without aromatic amine.

Wide range of applications

Irgastab PUR 71 fits a various of targeted applications. 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 anti-scorch 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.
