Why should flame retardant PP masterbatch be selected preferentially for flame retardant PP materials

(Summary description)In the process of PP processing, additive flame retardants are usually not melted. Therefore, in order to obtain the best physical and mechanical properties and flame retardant properties of flame retardant materials, flame retardants must be evenly distributed in the whole base material. Therefore, they should be added into the mixer earlier than plasticizers and other processing aids. At the same time, efficient mixing equipment (such as twin-screw extruder and continuous batcher) should be used and maintained Possible low processing temperature

In addition, the pre dispersion of flame retardants also contributes to their uniform distribution in the substrate. However, due to the low viscosity of melt PP, the shear stress during processing is small, so it is difficult to make the filler type flame retardant disperse well in PP in any case. If the flame retardant and the carrier were mixed to form a masterbatch containing 50% - 60% of the flame retardant, and then the masterbatch was used to flame retardant PP. The flame retardant masterbatch can use polyolefin or its mixture as carrier. At present, many manufacturers supply flame retardant masterbatch for PP, and its composition can be adjusted according to user requirements.

 

The compatibility between Sb2O3 and PP can be further improved by acrylic acid modification and Sb2O3 superfine, and better comprehensive properties can be obtained. Among the brominated flame retardants, brominated epoxy resin has excellent fluidity, high flame retardant efficiency, excellent thermal stability and photostability. At the same time, it can make the flame retardant materials have good physical and mechanical properties, no frost, and has a broad market space.
