Classification Of Flame Retardant Masterbatch

Due to the advantages of flame retardant masterbatch (masterbatch) used in plastics in flame retardant efficiency, environmental protection, improved production efficiency, convenience, etc., it has become an effective substitute for traditional flame retardants and has been widely used in plastic

manufacturing. Pelletizing, extrusion, injection molding, etc.

The flame-retardant masterbatches that can be promoted are halogen-based (Br, Cl), phosphorus-based (red phosphorus, phosphorus compounds, etc.), nitrogen-based (usually called intumescent flame-retardant masterbatch) and inorganic flame-retardant masterbatch (hydrogen Mainly alumina, magnesium hydroxide, etc.).

Halogen-based flame-retardant masterbatch (masterbatch) is currently the most respected flame-retardant masterbatch in most resins. The reason is that its own organic properties make it have a better affinity with plastics, so the mechanical properties of the finished products are reduced. Less and high flame retardant efficiency, less addition in resin, high cost performance. The disadvantage is that some are biologically toxic, which is prohibited in some international standards. And due to poor environmental performance, especially in Europe, there is a tendency to be eliminated.

Phosphorus-based flame-retardant masterbatch is also a commonly used product. In some resins, its flame-retardant efficiency is even higher than that of halogen-based resins. However, it has poor color coordination, poor compatibility, low oxygen index, and influence on processing technology. Many shortcomings such as low applicability can only be used by special industries. Intumescent flame-retardant masterbatch has a narrower application range due to its low flame-retardant efficiency and easy "foaming". Inorganic flame retardant masterbatch, such as magnesium hydroxide. Its flame-retardant products are environmentally friendly, do not emit toxic gases, emit small amounts of smoke, and have a high oxygen index of flame-retardant plastics. However, due to the excessive addition of the ideal flame-retardant standard and the natural inconsistency of inorganic and organic substances, Although the finished products obtained after modification are still difficult to meet the needs of most industries, their promotion is subject to certain restrictions. It is believed that after its technological advancement, relying on its environmental protection advantages can gradually be recognized by the market.
