New Firepel K120 FR System: Halogen-free Resins for Lighter Weight Composites

News International-French

6 Apr 2012

AOC announces its latest technology, Firepel K120, a revolutionary new resin system which is halogen-free, fire-retardant and produces lighter weight composites.

Firepel K120 uses a unique intumescent technology that meets fire performance requirements, uses sustainable technology, and does not require antimony or aluminum trihydrate (ATH).

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.  

Firepel K120: Halogen-Free and ATH-Free Technology
“When developing Firepel K120, we wanted to utilize halogen-free technologies to create the highest fire-retardant and low-smoke characteristics possible,” said Fletcher Lindberg, Business Manger, Open-Mold 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.”

Low Fire, Smoke and Toxicity
Firepel K120 unsaturated polyester greatly 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:
▪ ASTM E162, Standard Test Method for Surface Flammability of Materials Using a Radiant Heat Energy Source,
▪ ASTM E662, Standard Test Method for Specific Optical Density of Smoke Generated
by Solid Materials and,
▪ SMP 800-C, Toxic Gas Generation

Safer railcars, buses and vans
Initial applications for Firepel K120 are in fiber-reinforced polymer (FRP) composites for mass transportation railcars, buses and vans.  Typical candidate components include:
▪ arc barriers
▪ cab fronts
▪ nose cones
▪ driver control desks
▪ interior wall panels
▪ exterior cladding
▪ seat shells and tables
▪ handles and head supports
▪ flooring and ceilings and
▪ ventilation ducting

Firepel K120 is engineered for the hand lay-up and spray-up composite manufacturing processes.  AOC’s technical support team will help manufacturers maximize results through personalized consultation and discussions of K120’s processing guidelines.
