Halogen-free organic phosphorus flame retardant for modifying PA6/PA66/PPA, Deflamer®️ LFR-5009

Low corrosion to screws, UL 94 V0(0.4mm),low mould deposites

White powder, high hydrophobicity, high temperature resistance and non-migratory, higher thermostability; it is mainly used for modifying nylon (PA6 and PA66, PPA).


1.Compliance with ROHS and REACH requirements.

2.Mainly used for nylon (PA6 and PA66, PPA).

3.Higher thermostability and processability than general nitrogen-based flame retardant.

4.Low smoke during process that can greatly reduce the corrosive gas to make sure lower corrosion to screws.

5.Under high temperature and humidity, finished products with LFR-5009 has stable properties, no blooming. Longstanding injection molding with low deposite and sticky.

6.Finished product with LFR-5009 is recyclable.
