AOC has introduced Firepel K140-MTI, a high-performance resin system for interior mass transit and architectural and building applications.

The one-part system is halogen-free and does not require antimony or aluminium trihydrate (ATH) to achieve its fire retardant and low smoke properties. Composites made from Firepel K140 are up to 30% lower in density than standard composites using ATH, AOC reports, meeting the automotive and construction industries’ increasing needs for lighter weight parts.

The resin uses a combination of proprietary flame and smoke retardant technology to achieve its performance, resulting in excellent handling characteristics, cure properties and higher glass content. Its unique combination of properties is said to result in composite parts that are easier to fabricate, stronger and lighter weight than mineral filled products.

“Firepel K140-MTI exhibits outstanding flame and smoke properties, and offers many handling and processing benefits compared to other products on the market,” says Mike Diehl, Business Manager for AOC.

Based on the following testing, Firepel K140-MTI exceeds the requirements of mass transit applications in North America, Europe and Asia, and achieves a Class A rating Building Code Standard:

  • CEN TS 45545 European Consolidated Railway Standard (HL2 rating);
  • SMP 800-C Toxic Gas Generation Standard;
  • 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;
  • ASTM E 84 (UL 723) Standard Test Method for Surface Burning Characteristics of Building Materials. 

Firepel K140-MTI is engineered for the hand lay-up, spray-up and RTM manufacturing processes.
