Unsaturated polyester (UPR) is everywhere, boats, bathroom panels, FRP gratings, yet its inherent flammability is a design risk. A robust flame retardant for unsaturated polyester resin must deliver low smoke, low toxicity, and strong char formation without hindering curing or reducing Barcol hardness. Through synergistic blends of ATH, antimony-free smoke suppressants, and phosphorus donors, Niknam Chemicals Pvt. Ltd enables UPR laminates to reach UL 94 V-0 or Class 1 flame spread while keeping viscosity and gel times predictable for open-mold or RTM processes.
Fabricators benefit from easier wet-out, steady exotherm control, and minimal post-cure discoloration. Finished parts show less dripping, slower flame propagation, and durable mechanical properties, even after weathering or chemical exposure. Whether you’re producing translucent roofing sheets or corrosion-resistant tanks, a smart FR system keeps your product line compliant with marine, building, or transportation codes. Want composite parts that tick every safety box without slowing your production line?
