ICL announced on December 11, 2024, the launch of VeriQuel R100, an innovative, reactive phosphorus flame retardant designed for rigid polyurethane insulation products. This new product targets applications such as sheathing, in-wall insulation, and PIR roofing, which are critical for commercial construction.

The company invested over $2 million in research and development for VeriQuel R100, which offers a more sustainable alternative to traditional additive flame retardants. Its patented reactive nature means it chemically bonds with the polymer matrix, ensuring long-lasting performance and stability while eliminating migration potential.

VeriQuel R100 is compatible with existing manufacturing processes, facilitating an easy transition for manufacturers seeking to improve product sustainability and compliance without additional costs. Four leading U.S. commercial roofing companies have already launched products utilizing VeriQuel R100, with six more in the U.S. and Europe in development.
