Replacement of Antimony Oxide, Antimony-free Synergistic Flame Retardant for Polyester FR-100
Product Description：
FR-100 is a white powder, which is designed for PBT as a substitute for antimony oxide (Sb2O3)
synergistic flame retardant. Antimony-free, high-efficiency product offers an advantageously
condensed phase mode to protect the polymers. It has good compatibility with resin, paving the way
for minimising the brittleness of polyester compounds. Multiple color solutions would be implemented
to enable broader applications of flame retarded materials.
Applications：
FR-100 is developed especially for use in polyester. It is particularly suited for both glass-fiber
reinforced and non-reinforced PBT.
Formulation:
In 30% glass-fiber reinforced PBT, a dosage of about 5% of FR-100 is usually sufficient to obtain
the UL 94 V-0 classification, with tensile and impact strength comparable to conventional antimony
synergistic flame retardant. Subject to the polymer grade, processing conditions and glass-fibre
reinforcement, the dosage of FR-100 may vary.
The flame retarded polyester compounds exhibit good physical and electrical properties in repeated
secondary treatment. Non-halogenated flame retardant compliants with ROHS and REACH
regulations.
Same colour as the antimony synergistic system, no colour-matching issues
