CHELMSFORD, Mass.—FRX Polymers Inc. has made available its Nofia non-halogenated polyphosphonates for use in UL 94 V-0 high-temperature polyurethane flexible foams for the transportation and electronics industries.
The Nofia phosphonate oligomers are a flame retardant and heat stabilizer in polyurethane flexible foam products and enable them to meet the UL 94 V-0 fire standard, according to a FRX news release. It also retains mechanical performance after severe thermal aging tests performed at 150 degrees Celsius.
FRX said key targeted applications include automotive under-the-hood parts, cushion/gaskets for electric vehicle battery packs, noise/vibration/harshness foams for various transportation parts, and gaskets for electrical and electronics components with UL 94 V-0 requirements.
The flame retardants can be added into the process in both powder form or as a liquid polyol solution, which improves process efficiency and provides a more sustainable solution, said FRX.
FRX said Nofia FR allows fire retardant polyurethane foam to handle higher temperatures both in terms of peak temperature and continuous use temperature. It maintains good dimensional stability and required mechanical performance after exposure to long-term heat aging.
Nofia FR are tough, transparent and possess high melt flow for use in consumer electronics, textiles, building and construction and transportation markets, FRX said. Nofia phosphonates replace halogenated flame retardants, which are being phased out due to toxicity concerns. They are sold as polymeric flame retardant additives, flame-retardant engineering plastics and as reactive flame retardant additives for thermosetting resins.
FRX said the Nofia phosphonates are produced using sustainable green chemistry principles, such as a solvent-free production process, no waste byproducts and near 100 percent atom efficiency.
