Borealis and Borouge new halogen-free flame retardant cable jacketing makes it possible to achieve high CPR fire rating including “d0” – no flaming droplets. The new formulation offers good mechanical properties, enables high speed cable production and can achieve CPR...
Tannic acid is found in tree bark and other plant materials and can be recovered from bio-based industry waste streams. It was tested as a flame retardant additive in DGEBA epoxy at 0.1 – 8% (and neat epoxy), by mixing into the epoxy before hardening and cur-ing....
A melamine salt of pentaerythritol phosphate showed to be an effective PIN FR in polypropylene, with less toxic fire gases than neat PP. Phosphoric acid, pentaerythritol and melamine were react-ed at 4:1:3 ratio, then extruder mixed into polypropylene at 0 – 25%. With...
Zinc oxide coated cellulose nanocrystals, sourced from wood, were tested in 4mm HDPE sheets. Zinc oxide is widely used in for example sunscreens. The zinc oxide (50%) – cellulose (50%) nano-particles were ground to a particle size < 44 µm, then screw extruded into...
Mineral PIN FRs prove effective to improve fire safety of insulation boards made from non-reusable plant fibre wastes. Sodium carbonate decahydroxide [Na2CO3.10H2O] and alumina trihydroxide [Al2O.3H2O] were tested as PIN FRs, at 0 – 30% loading, in thermal insulation...
