Halogen-free organic phosphorus flame retardant for modifying PBT/PET/ PTT ,Deflamer®️ LFR-8004

Excellent electrical property, UL94-V0@0.4mm

White powder, high bulk density, low dust, high hydrophobicity and temperature resistance without migration. It is mainly applied in PBT, PET, PTT (glass fiber reinforced and unreinforced), and good flame retardancy synergy with nitrogen based flame retardant.


1. Applied in PBT, PET, PTT (glass fiber reinforced and unreinforced)with high heat stability, hydrophobicity and hydrolysis resistance.

2. Excellent electrical property and thermostability, low smoke density and no color influence to the finished products, such as white, natural color etc.

3. Good processability with less dust, environmentally friendly.

4. Synergy with nitrogen based flame retardant (such as MCA and MPP) can get better balance and cost performance.

5. Finished product with LFR-8004 is recyclable.
