- NILBURN OP117 is a suitable flame retardant for many types of flexible slabstock polyether and moulded foams. The product is typically recommended for the production of flame retardant foams required to resist ignition from low intensity flame sources as described in Federal Motor Vehicles Safety Standard No.302 and also to meet California Bulletin 117 requirements. Owing to its high efficiency, its dosage required for the same flame retardancy is almost 50% lower than traditional flame retardants.



- NILBURN OP117 is very hydroscopic. Please keep containers tightly closed and prevent the ingress of moisture or other forms of contamination . Store in dry ventilated place.
