How many options are there for filling pp flame retardant masterbatch? What kind of filler can be added to PP flame retardant masterbatch? The existing PP flame retardant system conflicts with calcium carbonate, that is to say, the addition of calcium carbonate will reduce the flame retardant performance of the material. If it is to increase rigidity and surface strength, it is recommended to add talcum powder or barium sulfate.
Calcium carbonate affects which flame retardants and phosphorus-nitrogen system intumescent flame retardants, which will lead to a decrease in flame retardancy. It is usually recommended not to add it. Because the addition of calcium carbonate as a filler may be for cost-saving considerations, but due to the decrease in flame retardancy to meet certain flame-retardant requirements, the addition of flame retardants can only be increased, which may result in higher costs.
