HaflonTMseries Halogen-free flame retardants
Halogen-free flame retardants used in TPU
NP0836
Product Features
NP0836 is a halogen-free flame retardant based on organic phosphinates. The product achieves its flame retardant effect through intumescence. The thermoplastic polymer with NP0836 foams and crosslinks on exposure to flame and forms a stable char at the surface acting as a barrier. The protective layer provides a heat insulation effect, reduces oxygen access and prevents dripping of molten polymer.
NP0836 is developed especially for TPU. TPU with NP0836 can pass the tests of UL94 V-0. The products with NP0836 have the characteristics as smooth appearance, no precipitation, excellent water and migration resistant, good thermal stability, no toxicity and lower smoke generation.
