Product description
TZ-911P series of high efficiency halogen-free flame retardant is a kind of double ring cage like polyphosphonate flame retardant with different chemical structure. No halogen, high efficiency, durability, smoke-free, dust-free, high thermal stability, good compatibility with many polymers, in the molten state in the forming temperature of the polymer, easy mixing, can achieve good effect of flame retardant used alone has little effect on other properties of materials, flame retardant polyester, can be applied to polyamide, unsaturated resin, epoxy resin, especially as PET, PBT (non glass reinforced) ideal additive type flame retardant.


Product index
Appearance: white powder
Molecular weight: 18000
Whiteness: 98%
Flow temperature: 200 degrees centigrade
Start: the decomposition temperature more than 380 DEG C
Phosphorus content: 8%


Application examples
The addition of PET to the oxygen index of LOI = 30, the vertical combustion of nearly V-0:
TZ-911P flame retardant: 4.5~5wt%.


Scope of application
TZ-911P flame retardant is very suitable for PET spinning; rubber, silicone, PA, and PA plus fiber; polyurethane, halogen-free flame retardant, flame retardant with smoke eliminating effect, its principle is through reducing the heat, burning it releases nitrogen dilution of flammable gas, char formation air to produce flame retardant, the flame retardant properties reached UL94-V0.


Usage method
The flame retardant is mixed with the flame-retardant polymer or other materials in different proportions (depending on the flame retardant grade of the products). After normal drying (the same drying condition with the flame retardant polymer), then spinning or preparing plastic products. The spinning or molding conditions are basically the same as those of the flame retardant polymer, but the temperature can be reduced properly.


Packing method
25 kilos / bags with lined PE bags should be kept in the ventilation and drying place.
