The polyurethane foam market continues to innovate, diversify, and grow into new end-use applications. From high-volume to high-performance materials; the adaptability, durability, and performance of polyurethane chemistry for rigid, molded and slab-stock foam, has allowed designers and manufacturers to meet performance challenges and efficiencies that previously couldn’t be met.

Government regulations and the automotive industry are clearly increasing the needs for more sustainable materials to be used in car interiors. The quality of air in car interior has been a continuously evolving topic to improve health and safety of car passengers. The automotive industry has given additional emphasis to the volatile component emissions of the final article.

IRGASTAB® PUR 70

Anti-scorch package for Polyol and Polyurethane foams to meet emission requirements

IRGASTAB PUR 70 is a novel anti-scorch additive that provides extremely low emissions and reduces significantly the aldehyde emissions in Polyol and PUR foams. This addresses the increasing challenge to meet emissions requirements of the automotive industry as well as in the furniture and bedding industry. Due to its outstanding gas fading resistance and light-induced discoloration IRGASTAB PUR 70 can be used in applications outside automotive where foam whiteness is key.

Features and Benefits

Significantly reduces emissions in Polyol and PU foams
Does not release aromatic amine or aromatic solvents
Outstanding stability against auto-oxidation
Good anti-scorch performance in PU flexible foams
Can meet the most stringent automotive requirements
Outstanding gas-fading resistance and extremely low light-induced discoloration
