FERROFLAM PBT RPM 5408 is the masterbatch developed especially for PBT, also glass-iber reinforced, intended to be used for electrical switches connectors, domestic appliances and microwave ovens, etc. It is also suitable for a blend component in other polyester like PET.
- Formulation
In glass-fiber-reinforced PBT, a recommended dosage should range from 13 to 15% (by wt) based on the weight of polymer, depending on PBT grade, processing conditions and glass fiber content and the required fiame retardancy class.- Processing
FERROFLAM PBT RPM 5408 is endowed with high thermal stability particularly for all polyester grades and glass-fiber reinforced. It is suitable temperatures rise up to 320°C without degrading or releasing die build-up or carbonaceous residues in hot runners. However, consider the following processing instructions:
1) Polymer pellets/powders which are processed together with FERROFLAM PBT RPM 540B should, if necessary, be pre-dried.
The residual moisture content should be under 0.1%. Many polymer grades fulfill this requirement without pre-drying.
2) The maximum temperature of the polymer melt should not exceed 320°C.
3) Drying of the pellets immediately after compounding is recommended. It is best to use a strand pelletizer with as short a water bath as possible.
