St Louis, Missouri -- A new high-density rigid polyurethane foam that meets specifications for flame retardancy and helps extend uses into construction and mass transit markets has been launched in the US by BayOne Urethane Systems llc.
The group's new material is a high-density rigid polyurethane foam that meets ASTM E84 Class 1 requirements, when moulded to a density of 20 pcf as foam boards.
BayOne said the product is largely aimed at moulders of fibre-reinforced structural foam board, but adds that it would work equally well to make architectural parts, where flame retardant properties are critical.
Meeting the ASTM E84 Class 1 requirement potentially opens up new applications in the construction and mass transit markets, as well, said BayOne, adding that the material is available for customer evaluations.
"The development of this system proved a real challenge for BayOne's technical team," commented Mark Vanover, marketing manager, BayOne Urethane Systems, in a company statement. The higher density of the foam effectively meant more fuel in the E84 burn test, creating technical hurdles as far as retarding smoke generation and flame-spread characteristics, Vanover said: "But through our extensive technical expertise, we were able to overcome this challenge, resulting in a novel product that has utility beyond its original application."
BayOne is a US joint venture between Bayer MaterialScience llc and PolyOne Corp.
