Due to flame retardant masterbatch (masterbatch) in the plastic used in flame retardant efficiency, environmental protection, improve the efficiency of production, the advantage of the many aspects, such as convenient has become an effective alternative to conventional flame retardants, and is widely used in plastic granulation, extrusion, injection molding, and other aspects.
Now to popularization and application of flame retardant masterbatch with phosphorus-containing (Br, Cl), phosphate (red phosphorus and phosphorus compounds, etc.), nitrogen (commonly referred to as expansion type flame retardant masterbatch) and inorganic flame retardant masterbatch (aluminum hydroxide, magnesium hydroxide, etc.).
Phosphorus-containing flame retardant masterbatch (masterbatch) is the most to promote today in most resin flame retardant masterbatch, the reason is that its own organic makes its better affinity with plastic, and mechanical performance of manufactured goods fell by less and flame retardant of high efficiency and less amount in the resin, high cost performance. Defect is part with biological toxicity, banned in some international standards. And due to poor environmental performance, especially in Europe, has a tendency to be eliminated.
Phosphorus-containing flame retardant masterbatch also belongs to the application of common products, in some of the resin which has even higher than that of phosphorus-containing flame retardant and bad but its color coordination, poor compatibility, low oxygen index, the processing technology of low applicability of disadvantages and often can only be used by special industry. Expansion type flame retardant masterbatch for the flame retardant efficiency is low and easy to "foam" and so on many inadaptability, its application scope is more narrow. Inorganic flame retardant masterbatch, such as magnesium hydroxide. Its flame retardant products, environmental protection is good, do not emit toxic gases, small amount of smoke and flame retardant plastic oxygen index is high, but because of its high ideal flame retardant standard amount together with the natural dissonant sex of inorganic and organic matter makes it while in after modification treatment of manufactured goods is still difficult to adapt to the needs of most industries and their promotion. Believe that after the technology to progress, relying on the advantages of environmental protection can also gradually accepted by the market.
