Resonance P-series and T-series polyols have high aromaticity, and a range of functionalities. As well as improved fire performance, Hexion says catalysts and fire retardant additives can be adjusted in the formulation.
A higher compression strength is allied to improved dimensional stability, the company says. Also claimed is an enhanced compatibility with isocyanates, co-polyols and additives, leading to finer cell structures.
Hexion adds that the T-series polyols offer varying levels of nitrogen content, giving high reactivity. This means they are a good fit for applications where rapid cure is important, such as spray foams and foams for appliances. As they are non-volatile, VOC emissions can be reduced.
‘We’re excited to offer these innovative raw materials to the polyurethane industry,” says JP Aucoin, SVP and general manager of Hexion’s global phenolic specialty resins business. ‘Recent accidents around the globe have put the fire, smoke and toxicity properties of insulation under a microscope, and manufacturers are looking to improve product safety as well as mechanical performance and manufacturing efficiency. Our novel Resonance P-Series and T-Series polyol portfolio provides an attractive, new alternative to current technologies.’
