Product information

Polymeric flame retardants OL1001 and OL3001 are oligomers with low molecular weights and are reactive flame retardant additives. They are phosphorus based with phenolic end groups suitable for flame retarding thermoset resins, such as unsaturated polyesters, epoxy, polyurethane and polyurea. They are transparent and highly soluble in the typical solvents used in thermoset resin processing.
