Floreon Therma Tech Flame Retarded Grade

Floreon Therma Tech Flame Retarded Grade is a PLA based compound intended for durable applications requiring flame retardancy. This developmental grade contains a flame retardant, impact modifier, nucleating agent. The material is based on PLA and is designed as a drop in replacement for ABS in injection molding, extrusion and 3D printing. Drying of the material is recommended to ensure melt stability and limit degradation of the material during processing.

Features & Benefits

Labeling Claims
Materials Features
  • Flame retarded (UL94V-0)
  • Nucleated to allow high crystallinity and heat deflection temperature
  • High Impact Strength
  • High renewable content
  • Developed for applications requiring fire resistance
  • Durability comparable to flame retarded ABS
  • Contains elastomeric impact modifier
Floreon is a HALOGEN FREE alternative to Flame Retarded ABS
  • Floreon’s base material (PLA) is ideally suited to chemical recycling.
  • In pilot plant /kilo lab trials with the Biorenewables Development Center, Floreon were able to recover 100% of the lactic acid feedstock in a simple and fast reaction, removing ALL flame retardant and fillers by simple filtration.
  • This feedstock can then be used to regenerate virgin polymer with no downcycling.
  • Is commercially viable.
  • Functions the same as traditional plastic.

Technical Details & Test Data

Processing Information
  • Floreon Therma Tech compound can be processed on general purpose injection molding equipment and a screw designed to minimize shear and residence time will produce the best results.
  • The material is typically injection molded using a melt temperature of 200°C with a mold temperature of 26°C. This grade can be extruded from as low a temperature as 170°C, but processing temperatures must never exceed 240°C.
  • Melt temperature has a significant effect on mold flow with this grade and for thinner walled parts a melt temperature of 230°C may be required.

Mold 26°C
  • Floreon resins must be dry before use in melt processing; a water content of less than 250 ppm is recommended, otherwise product performance will be significantly degraded.
  • The solid resin will not be damaged by absorption of atmospheric moisture providing it is stored in a cool environment at temperatures not exceeding 25°C.
  • As with unmodified PLA, Floreon resins should not be left in the barrel at high temperatures for extended periods of time (5 minutes and above) as this will degrade the material resulting in a significant drop in viscosity and resin integrity.
  • Drying under vacuum at a maximum temperature of 90°C for 2 hours is recommended to ensure best results. The material can be dried above this temperature but some ‘clumping’ may occur, with pellets sticking together. This is reversible and the pellets can be separated on cooling with mild agitation.
Benchmarking of Floreon vs ABS

Floreon’s durable and flame retarded grades were tested alongside a high performance ABS and flame retarded ABS grade to provide a benchmark. Floreon is able to match the notched impact strength of ABS. Molded products have also passed all necessary drop testing.
