LFR-8020 Halogen-free flame retardant specialized for Polyolefin

LFR-8020 is halogen-free phosphorus based flame retardant. It is white powder and mainly applied to polyolefin with excellent flame retardancy, low density and high mechanical property, etc.


Item Unit Standards
Phosphorous content %(w/w) 16.0-20.0
Nitrogen content %(w/w) 19.0-23.0
Bulk density g/cm3 0.30-0.40
Thermal decomposition temperature ≥270
Particle size(D50) μm <5.0


a. Blending with thermoplastic plastics, LFR-8020 performs excellent processing stability. LFR-8020 is mainly applied to PP-H, PP-B, HDPE, LDPE, EVA and other resins.
b. A dosage of 18-20 wt% in PP, combined with a little PTFE, can reach good flame retardant performance, and achieve UL 94 V-0(thickness at 1.6mm). Compared with MDH, LFR-8020 has lower dosage, lower density, and can improve mechanical property of polyolefin. Meanwhile it has excellent heat stability and processing property.
c. LFR-8020 is weak acidic, so acid-resisting machinery is suggested to molding (extrusion molding and injection molding) below 250℃.

Packaging & Storage:

20kgs in paper-plastic composite bag with PE inliner.
Seal and store in dry, dust-proof and cool place.
