This high efficiency flame retardant is used as substitution of Sb2O3, and it is different from zinc borate, hydrotalcite or
other kinds of synergists. At present, the cost-saving 2000A is mainly used in the modification of ABS, HIPS, PP, PBT,
PA and other kinds of flame retardant.
I. Main Features
1. Good thermal stability; improving the tinting strength without obvious discoloring.
2. When combined with Sb2O3, it can save the dosage of Sb2O3 and maintain more than 90% of mechanical property.
3. With the excellent performance of high brightness, it can save the cost of titanium dioxide.

Ⅲ. Flame Retardant Features
1. With the excellent performance of high brightness and high temperature resistance(TGA 1% mass loss temperature:
>600℃), it is perfectly applicable to PA, PBT, PET, PP, ABS, HIPS and PE, etc.
2. This high efficiency flame retardant is used as substitution of 30%-50% antimonous oxide, thus saving the production
cost.
3. Products using 2000A have same performance in tensile strength and bending strength with products using antimonous
oxide modifications. It also has functions of flame retardant, smoke suppression and anti-dripping.
