Flame Retardants, Polyethylene Terephthalate (PET)

PET-B-40C2 Halogen Free Flame Retardant Masterbatch

PET-B-40C2 is a halogen-free flame retardant white masterbatch formulated for high-temperature PET and PA applications. It uses a high-purity flame retardant system and a PET carrier to deliver stable, clean, and efficient flame retardancy in PET fibers, films, sheets, and engineering filaments. PET-B-40C2 maintains tensile strength, elongation, gloss, and surface quality while providing strong thermal resistance and consistent dispersion during high-speed melt processing.

Attributes

Key Features and Benefits

High flame-retardant efficiency enables UL94 V-0 performance at low 12–16 percent loading.
Halogen-free technology ensures low smoke, low toxicity, and environmental compliance.
Thermal stability ≥300 °C supports PET and PA high-speed spinning and extrusion.
White masterbatch with no blooming maintains clarity, gloss, and colour stability.
Excellent dispersion reduces dusting, contamination, and filter blockage.
Strong retention of tensile, elongation, and filament strength.
PET carrier provides full compatibility with PET melts and reduces processing defects.
