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.
Improving the performance, health, and safety of polymers for automotive applications has been an innovation driver that has benefited so many industries and applications. As a formulator, you now have options for stabilizer packages that can be optimized for your performance requirements and costs. Which package has the right balance of properties for your application?
