Flame retardant masterbatches are widely used in the flame retardant industry, including pp-301 pp flame retardant masterbatches. What are the characteristics of the two? What's the difference? Let's take a look together. Talc manufacturer

Classification of flame retardant masterbatch the characteristics of each classification

1. The flame retardant masterbatch (PP-301) is added 3-5% to the new homopolymer PP to extinguish the fire within 3 seconds.

PP flame-retardant masterbatch has good flame-retardant effect, small addition amount, high whiteness of the masterbatch, can be matched with all colors without affecting the color of the product.

PP flame-retardant masterbatch has excellent thermal stability, the product can be processed repeatedly, the flame-retardant effect, strength color are significantly changed.

PP flame-retardant masterbatch is environmentally friendly bromine, non-toxic low-smoke, thermal cracking burning does produce toxic DBDO DBDF, does affect the environment.

PP flame-retardant masterbatch is resistant to cold weather, has strong anti-ultraviolet ability, is easy to precipitate, can improve the forming fluidity of the product.

2. What flame retardant factors are contained in PP flame retardant masterbatch? With the advancement of science technology the improvement of living standards, polymer materials, especially synthetic polymers: such as plastics rubber, have become more more important in people's lives, their applications have been expanding year by year. However, most organic polymer materials have varying degrees of flammability in the air. In order to realize their applications in many industries such as military, aerospace, transportation, electric power civil use, flame retardant modification has become a new topic. At present, the ideal flame-retardant modification method for plastics is often to improve the fire-retardant performance of plastics by adding products such as flame retardants flame retardant master batches.

1. According to the flame retardant elements contained: According to the flame retardant elements contained, flame retardants can be divided into halogen flame retardants, phosphorus flame retardants, nitrogen flame retardants, phosphorus-halogen flame retardants, phosphorus -Nitrogen flame retardants other categories.

2. According to the different components: According to the different components, it can be divided into three types: inorganic salt flame retardant, organic flame retardant organic inorganic mixed flame retardant.

3. Applicable flame retardants for each resin: according to the composition of flame retardants, additive flame retardants mainly include inorganic flame retardants halogen flame retardants

4. According to the method of use: according to the method of use, flame retardants can be divided into additive type reactive type. Additive flame retardants play the role of flame retardants mainly by adding flame retardants to combustibles.

Characteristics of PP flame retardant masterbatch:

1. Easy to use: flame retardant masterbatch (masterbatch) is mostly tablet-like strip-like tablet-sized particles, which are exactly the same size as general plastic particles, which improves their compatibility, makes it easier to disperse add, is hygienic reduce volatile waste.

2. Reduce costs increase the added value of products: often through the addition of flame-retardant masterbatch (masterbatch), general plastics have are close to the application requirements of engineering plastics, which increases the added value of products reduces the cost of raw materials.

3. Good compatibility with resin: In general, the flame retardant masterbatch (masterbatch) has been specially treated to improve its compatibility with plastic resin, so that its addition in the resin will change even if the amount is large. Prone to problems such as delamination, blooming, patterns, etc. Polypropylene (PP) flame retardant masterbatch

1. The flame retardant masterbatch (PP-301) is added 3-5% to the new homopolymer PP to extinguish the fire within 3 seconds.

2. The flame-retardant masterbatch (PP-303) is added 8-10% during injection molding of the new copolymer PP material, it will be extinguished in 3 seconds after leaving the fire.

3. Flame-retardant masterbatch (PP-304) is added to the extruded PP hollow board, adding 3-6%, leaving the fire 3 seconds to extinguish.

PP flame-retardant masterbatch has bromine-antimony composite flame-retardant masterbatch (flame retardant component 85%, carrier 15%), especially suitable for PP (polypropylene) flame retardant, in polypropylene hollow board, electrical appliance shell, automobile center console It is widely used in materials other aspects, its flame retardant effect performance, especially incomparable thermal stability, excellent dispersion, flame retardant effect. It can achieve V0 flame retardant PP.

The characteristics of PP flame-retardant masterbatch: PP flame-retardant masterbatch has been optimized for many times. Because the purity of the masterbatch is high, it has good compatibility with resin, excellent dispersion performance, easy to mix no dust. The mechanical properties remain excellent.

PP flame-retardant masterbatch has good flame-retardant effect, small addition amount, high whiteness of the masterbatch, can be matched with each total color without affecting the color of the product.

PP flame-retardant masterbatch has excellent thermal stability, the product can be processed repeatedly, the flame-retardant effect, strength color are significantly changed.

PP flame-retardant masterbatch is generally used in 4-6% in homopolymer PP, which can reach UL94-V2 level (extinguish after fire); if used in homopolymer PP with copolymerized PP a large amount of toughening agent added, You need to add 2-4 more. In the case of an appropriate amount multiple doses, this product can do a strict UL94-V0 effect.
