Replacement of Antimony Oxide, Antimony-free Synergistic Flame Retardant for Polyester

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
