Polynt STYPOL® 040-8003 Flame-Retardant RTM Resin
Categories: Polymer; Thermoset

Material Notes: STYPOL® 040-8003 is a pre-promoted, flame-retardant polyester resin containing styrene monomer. It is especially formulated for production of reinforced plastic products using resin transfer molding (RTM). Certain applications with specific flame-retardant needs may require the addition of methyl methacrylate (MMA) and modest amounts of alumina trihydrate or antimony oxide/ammonium dimolybdate.

Features and Benefits:

  • Extremely fast wet-out
  • Early development of Barcol hardness
  • Good cure in thin sections
  • Excellent retention of physical properties after water boil
  • FMVSS 302 Flammability of Interior Materials - Passenger Cars, Multipurpose Passenger Vehicles, Trucks and Buses
  • Flame-Retardant meeting UL 94 Plastics Flammability Standard, VE-1 and VE-2 classification
Neat resin casting catalyzed with 1.0% benzoyl peroxide. Casting was cured at 180°F (82.2°C) and post cured for 1hour at 240°F (115.5°C).

Laminate - Resin initiated with 1.5% United Initiators Norox® Azox. The laminate schedule was 2 plies of 2.0 oz. CSM. Glass content was 25%. The panel was cured at room temperature for 1 week.
