Introduction:

Organic zinc salt flame retardant containing phosphorus is white powder with high temperature resistance and non-migration. It will be melt under high temperature that is benefit for melt blending with polymer, but won’t block spinneret orifice. It is especially applied to the halogen-free flame retardant of PET fiber and PET thin film system, and has good compatibility with matrix resin. It can also be applied to injection moulding of PBT and PET. It has excellent flame retardant efficiency with 8004 and nitrogenous-contained flame retardants.

Application:

a. 8012 can be applied to produce permanent flame retardant polyester such as polyester chip, filament, short fiber, thin film and so on. The produced flame retardant polyester chips have good performance in hue, spinnability, fibre strength and chromaticity. It can do spinning process through any spinning system. It has good thermostability, so it will not decompose in spinning process, and there is no peculiar smell at the scene of the spinning. It can improve antistatic property of polyester production. It is applied to each application area of conventional PET and PBT.

b. 8012 has prominent flame retardant efficiency, especially to polyester. It is used in the application of injection molding and fiber. Its addition in PET is about 5~15%. When 10~15% 8012 and 10~15% nitrogenous flame retardants such as MPP, MCA are mixed in PBT, the material can reach UL94V-0 (thickness of 1.6 and 0.8mm). In PET, little flame retardant can make the materials reach UL94 V-0.

c. The addition amount of flame retardant will change according to polymer grade, processing condition and content of glass fiber. 8012 can melt in the temperature of above 200℃, then mix with the melted polyester.
