White powder, small particle size, highly hydrophobic, high-temperature resistant, non-migrating phosphorus-based flame retardant, mainly used in engineering plastics such as polyester (PET, PBT) and nylon (PA6, PA66, PA46, including glass fiber-reinforced). Can be used alone or in synergy with nitrogen-based flame retardants for better results.

Product Property Particle Size (μm) Introduction
LFR-8001 Primary Component: Diethylaluminum phosphate

Phosphorus Content: 23-24%

<10 Mainly used in areas with smaller particle size requirements for flame retardants such as TPE, TPU, epoxy laminated printed circuit boards.
LFR-8002 Primary Component: Diethylaluminum phosphate

Phosphorus Content: 23-24%

<10 Primarily used in areas with ultrafine particle size requirements for powder particles, ultra-thin adhesives, flexible epoxy laminated printed circuit boards, and TPE, TPEE, PEBA.
LFR-8003 Primary Component: Diethylaluminum phosphate

Phosphorus Content: 23-24%

30-40 Mainly used in engineering plastics of polyester and nylon (including glass fiber-reinforced and non-reinforced).
LFR-8005 Primary Component: Phosphorus-nitrogen complex system

Phosphorus Content: 15-17%

30-40 Can be directly used in engineering plastics such as polyester (PET and PBT) and nylon 6 series, as well as TPE (TPEE, TPU, and PEBA).
LFR-8006 Primary Component: Phosphorus-nitrogen complex system

Phosphorus Content: 19-20%

30-40 Directly applicable to nylon 6 and nylon 66 series engineering plastics and TPE (TPEE, TPU, and PEBA).
LFR-8012 Primary Component: Diethylaluminum phosphate

Phosphorus Content: 20-21%

<40 High-temperature melting, conducive to melt blending with polymers, will not clog the spinnerets, suitable for PET fiber fabrics and PET film systems.
Can also be used in PBT and PET injection molding.
LFR-5001 Phosphorus Content > 24% <10 Flame retardant specifically for acrylic coating.
LFR-9001 Bromine Content: 13-14%

Phosphorus Content: 6-7%

<5 Environmentally friendly flame retardant for PP. Low addition amount, FF-PP V2 used for homopolymer PP, adding 1% can achieve UL94 V2.
LFR-9002 Bromine Content: 13-14%

Phosphorus Content: 6-7%

<5 Environmentally friendly flame retardant for copolymer PP.
