AOC has launched Firepel K120, a new resin system which they say is halogen-free, fire-retardant and produces lighter weight composites.
According to AOC, Firepel K120 uses a unique intumescent technology that meets fire performance requirements, uses sustainable technology, and does not require antimony or aluminum trihydrate (ATH). They say that Firepel K120 is ideal for in mass transportation applications due to the reduced weight and fire-retardant qualities. Parts using K120 have a potential weight savings of up to 30% compared to standard composites using antimony or ATH.
“When developing Firepel K120, we wanted to utilise halogen-free technologies to create the highest fire-retardant and low-smoke characteristics possible,” said Fletcher Lindberg, Business Manager, Open-Mould Reinforced Resins. “And because the resin’s excellent performance is achieved without ATH, Firepel K120 has a much lower specific gravity than ATH-filled composites, which makes it easier to process than traditional systems. As an added benefit, tensile properties are higher with K120.” Lindberg added, “This is break-through technology. There is no other resin on the market that performs like K120.”
AOC explain that Firepel K120 unsaturated polyester exceeds the requirements of mass transportation applications in North America and demonstrates low flame spread, low smoke and excellent smoke toxicity data when tested according to:
AOC say that initial applications for Firepel K120 are in fibre-reinforced polymer (FRP) composites for mass transportation railcars, buses and vans. They claim that typical candidate components include:
Firepel K120 is engineered for the hand lay-up and spray-up composite manufacturing processes. AOC say their technical support team aim to help manufacturers maximise results through personalised consultation and discussions of K120’s processing guidelines.
