MB2200

Features

MB220 is a kind of halogen free environmentally friendly flame retardant masterbatch with N and P, non-APP based system. MB220 has higher thermal stability and higher decomposition temperature. Besides, it can easily get processed. PP with MB220 can pass the tests of UL94 V-0 (1.5mm), 70℃×168hrs water-immersion (UL746C); besides, it can also pass the tests of GWIT 750℃ and GWFI 960℃. And it is free from the restrictions of RoHs Directive 2011/65/EU approved by the EU and the Council. Glass fiber reinforced PP with MB220 can reach UL94 V-0 (1.5mm) as well. The products with MB220 have the characteristics as low density, lower smoke generation and less mold corrosion. Polyolefin with MB220 will not have the phenomenon of water-sliding surface during the process of extrusion, and sieves can be added during the process.

Reference dosage

NOTES：

1. Because of the decomposition temperature of MB220 in nitrogen is 270℃, the processing temperature of twin screw can be adjusted higher accordingly, and a sieve can be put on the head of machine. Maintaining vacuum of the twin screw during the processing is also needed.

2.The substances which affect flame retardant performance: phthalocyanine green that contains Cl-1 toner will make the flame retardant loss effect. If the dosage of carbon black is higher than 0.5%, the flame retardant performance will be weakened.
