Key advantages

High decomposition temperature , Loss on Ignition is less than 1% at 400℃ , and it can be used in high temperature processing.

Application

It is used for polymer flame retardant systems with high processing temperature requirements such as high-temperature nylon, polyester, polyetherketone, polysulfone, and fluoropolymers whose processing temperature is higher than 290°C.

Packaging

Net weight 25kg/bag, Compound paper-plastic bag.

Storage and Attention

Keep in dry, room temperature and moisture proof condition, preventing the heating.
