Product Description |
NP2536 is a halogen-free flame retardant based on P&N system, is developed especially for TPE. The product achieves its flame retardant effect through intumescence. The polymer with NP2536 will expand when burning and form a stable carbon layer on the surface. The protective layer provides a heat insulation effect, reduces oxygen access and prevents the further spread of flame, plays a role in fire retardant.NP2536 less smoke, non-toxic, non-molten droplet, is a highly efficient environmentally friendly flame retardants.
