When using EcoFlame NP-1000, it should be mixed with other materials evenly at first. As for the twin-screw processing step, the temperature needs to be maintained at a proper value, and please keep good vacuum degree. On the other hand, inorganic fillings, such as glass fiber, French chalk, calcium carbonate, barium sulfate and others, all have influence over the final flame retardant performance.

This high-quality smoke suppressant is packed in 25kg craft paper bag with PE inliner, and other packages are also available if requested. The shipping weight is 17.5MT/20'FCL.
