Description
Chemdant***7
Chemdant***7 is Non-Halogen flame retardant based on
phosphorus and nitrogen synergism (not APP series).
Chemdant***7 was developed especially for use in polyolefin
and thermoplastic elastomer. It is suited for PP, PE, LDPE, HDPE,
EVA, TPE, TPU, TPO, SEBS, and PPO for injection moulding and
extrusion applications.
Chemdant***7 shows an excellent flame retardancy with low
amount of flame retardants, when incorporated into thermoplastics,
it shows good processing stability and
non-hydroscopic.
Chemdant***7 does not contain Pb, Hg, Cd, Cr6+, polybrominated
biphenyls or polybrominated diphenyl ethers. It is compliant with
the requirements of RoHS & WEEE Directive and halogen-free
specification IEC *********1.
Performance benifit
•Excellent flame retardancy - UL*4
V-O at 1.6 mm in polypropylene below *0% loadings with
0.2%PTFE.
• Very low smoke release; low smoke
density; very low CO & CO2 emissions.
• Low heat release; no corrosive
gaseous products.
• Homogeneous carbon layer with
closed cell structure.
• Enables the compounding of Flame
Retardant polyolefin with low density, high elongation and high
impact strength.
• Very low water solubility,
non-hydroscopic; improved resistance against water
extraction.
• Good thermal stability (wide
processing window), it can be process at **0℃.
• Can be available with appropriate
hindered amine light stabilizers
(HALS), unlike bromine-type flame
retardants.
• Less heat
discolorations.
• Significantly lower loading
compared to Al-trihydrate and Mg-hydroxide.
• Lower loading in comparison to
conventional ammonium polyphosphates.

Applications
1. LoadingLeveland ProcessingConditions
1.1TypicalLoadingLevel
Chemdant***7 is a white, thermally-stable
non-halogen flame retardant particularly useful in PP, PE, LDPE,
HDPE, EVA, TPE, TPU, TPO, PPO, SEBS etc. applications.
Low
density flame retardant polyolefin with high elongation and impact
resistance can
be
achieved withChemdant***7. Targeted applications are thick section
extrusions as well as injection moulded and selected thin wall
applications e.g. cable jacketing and films.
