What is a flame retardant masterbatch
With the progress of science and technology, improvement of living standards, polymer materials, in particular, synthetic polymers, such as plastic, rubber and so on in people's life more and more important in the position, its application shows the tendency of expanding year by year.But most universal polymer material has the characteristics of flammable in air, in order to achieve its military, aerospace, transportation, electricity and civil applications of many industries, such as, flame retardant modification to become the new subject.Is ideal for plastic flame retardant modification methods are often by adding flame retardant or flame retardant masterbatch products improve the fireproofing performance of plastic.
Flame retardant masterbatch which is also called flame retardant masterbatch, masterbatch fire prevention.To meet the requirements of plastic, rubber products realize the fire prevention and the type of product.
Flame retardant masterbatch (bromide/halogen), also known as flame retardant masterbatch is in plastic and rubber resin performance in one of the most excellent flame retardant products, flame retardant masterbatch (masterbatch) is on the basis of the flame retardant treated with the combination of many kinds of flame retardant ingredients, modification and association effect, and through the double screw or triple screw extruder through mixing, extruding and granulating and made a granular product.Unlike flame retardant, flame retardant masterbatch in resin is easy to add, clean sanitation, fire retardant efficiency is high, add a little, little influence on mechanical properties of the resin, not easy to happen after adding layered, decorative pattern, as well as the precipitation phenomenon, save manpower and material resources cost and time, and many other advantages.In general flame retardant masterbatch on the dispersion of the resin, liquidity, and the compatibility of resin and thermal stability and weather resistance are much better than common flame retardants, and formula of flame retardant masterbatch its efficiency and effectiveness of flame retardant (price) is far superior to ordinary flame retardant.So the flame retardant masterbatch as flame retardant plastic products achieve one of the best choice of fire prevention requirements, and an effective alternative to flame retardant powder,.
The characteristics of the flame retardant masterbatch
1, high flame retardant efficiency: the combination of various flame retardant elements and association effects between the flame retardant masterbatch (masterbatch) flame retardant efficiency is much higher than flame retardants (up to the same standard of flame retardant, addition amount is lower than in the plastics flame retardants, cost is also reduced).
2, easy to use: flame retardant masterbatch (masterbatch) mostly sheet or strip tablets size particles, coincided with the general plastic particle size, improve the mutual capacitance between them, and makes it easy to disperse and add health and reduce the volatilization waste.
3, it has good compatibility with resin: usually a flame retardant masterbatch (masterbatch) through special processing, improve the compatibility with plastic resin, makes it even larger amount in the resin is not easy to produce delamination, frosting, decorative pattern and so on.
4, reduce costs, improve product added value, often by flame retardant masterbatch (masterbatch) to join the general plastic with or close to the application requirement of engineering plastics, improves the product added value, reduces the cost of raw materials.
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.
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.
