Low Styrene Emission Resins

Cleaner. Safer. Compliant.

Designed to reduce VOC emissions and meet environmental regulations, our LSE formulations improve workplace safety and air quality, without compromising resin performance.

Environmental Responsibility Without Performance Loss

Low Styrene Emission (LSE) resins are modified unsaturated polyester systems formulated to minimize styrene vapor release during processing. This reduces worker exposure, improves shop air quality, and helps manufacturers comply with strict environmental regulations such as EPA, OSHA, and local VOC standards.

 

LSE technology can be applied to any resin family, including orthophthalic, isophthalic, NPG, PET hybrid, Bis-A, and vinyl ester, giving you cleaner operations without changing your process.
