With the progress of science and technology and the improvement of living standards, plastics and rubber play an increasingly important role in people's lives. However, since most of these plastics have the characteristics of low oxygen index and easy combustion in the air, it is difficult to apply them to industries with special requirements for fire protection without effective measures. At present, the ideal method of flame retardant modification of plastics is to improve the fire resistance of plastics by adding flame retardant or flame retardant masterbatch.

1、 About flame retardant masterbatch

Flame retardant masterbatch, also known as flame retardant masterbatch and fire retardant masterbatch, is an aggregate obtained by uniformly loading excess flame retardant in resin.

2、 Characteristics of flame retardant masterbatch

Compared with flame retardant, flame retardant masterbatch has better performance in storage and processing, and has the following characteristics:

1. High flame retardant efficiency: the flame retardant efficiency of flame retardant masterbatch is much higher than that of some single flame retardant;

2. Easy to use: the flame retardant masterbatch is mostly flake or columnar particles, which is just the same size as the general plastic particles, so as to improve the compatibility and reduce the volatilization waste;

3. Good compatibility with resin: due to special treatment, it is not easy to cause delamination, frost, pattern and other problems when a large amount of resin is added;

4. Reduce the cost and improve the added value of products: the addition of flame retardant masterbatch often makes the general plastics meet or approach the application requirements of engineering plastics, which improves the added value of products and reduces the cost of raw materials.

2、 What is the difference between flame retardant masterbatch and flame retardant

1. Flame retardant belongs to flame retardant additive, and flame retardant masterbatch is flame retardant material containing flame retardant.

2. Flame retardant masterbatch is one of the most excellent flame retardant products in plastics, rubber and other resins. Flame retardant masterbatch is a kind of granular product made by organic combination, modification and synergistic effect of various flame retardant components on the basis of flame retardant and through mixing, extrusion and granulation by twin-screw or three screw extruders.

3. Different from flame retardants, flame retardant masterbatch has many advantages, such as easy to add in the resin, clean and sanitary, high flame retardant efficiency, small addition amount, little impact on the mechanical properties of the resin, less delamination, pattern, precipitation and other adverse phenomena after addition, and saving labor, material cost and time.

4. In addition, the flame retardant efficiency and efficiency (cost performance ratio) of properly formulated flame retardant masterbatch are also much better than ordinary flame retardants. Therefore, at present, flame retardant masterbatch has become one of the best choices for flame retardant plastic products to meet the fire protection requirements, and has become an effective substitute for flame retardant powder.

3、 Will the use of flame retardant masterbatch affect other properties of the product

The reasonable functional flame retardant masterbatch is specially designed according to its different functional requirements to solve its compatibility with different resins, so that even if its amount in the resin is large, it will not affect other properties of the material. Due to the continuous progress of technology and equipment, the performance of functional flame retardant masterbatch is also continuously improved. In many aspects, products meeting all performance requirements can be produced through direct mixing with materials, and the plasticization is easier and the output is larger. Thus, the product cost is greatly reduced and the added value of the product is increased.

4、 Will the use of functional flame retardant masterbatch increase the cost?

This is true in most cases. However, in some cases, the use of flame retardant masterbatch is more economical than the use of flame retardants. To achieve the desired effect, the following two phenomena need to be considered:

1. In many cases, the flame retardants used by plastic product manufacturers are not the most economical, and they are not familiar with the flame retardants. Repeated tests during use cause waste of manpower and materials. However, flame retardant masterbatch manufacturers focus on flame retardancy and provide one-to-one technical guidance for free. Therefore, the above problems do not exist when using flame retardant masterbatch.  

2. The grade of products using flame retardant masterbatch is completely different from that of products using flame retardant, and the selling price is higher. The higher selling price is often higher than the increased cost of using flame retardant. In addition, the labor and material costs are saved, and the flame retardant masterbatch can create "profits". From this perspective, in some cases, the use of flame retardant masterbatch is more "economical" than the use of flame retardant.

In recent years, with the development of masterbatch industry, masterbatch has developed from simple coloring to complex and functional.

Zhantong flame retardant masterbatch: This product exerts the flame retardant effect through the carbon formation mechanism in the condensed phase, and the oxygen index of the polymer has a good correlation with the carbon formation amount during combustion, so as to obtain high-performance flame retardant effect.

Application of zhantong flame retardant masterbatch: flame retardant masterbatch is suitable for PP long and short filaments and PP non-woven fabrics; Flame retardant masterbatch is also applicable to the manufacture of communication, electrical appliances, electronic products, mine riot control devices, auto parts, medical appliances, household appliances, laboratory flame retardant materials, etc.

Technical indexes of zhantong flame retardant masterbatch:

Product characteristics: the company produces bromine antimony series flame retardant masterbatch and halogen-free flame retardant masterbatch (in line with the EU ROHS environmental protection requirements), especially for the development of non-woven fabrics. According to different conditions, adding 2-3% can pass the flame retardant British standard bs-5852 test, and it does not ignite. At the same time, it has the advantages of anti yellowing and reducing the dripping of combustibles.

Application: mainly used for flame retardant and fire retardant modification of non-woven fabrics. Flame retardant non-woven fabrics are widely used in soft furniture, mattresses, toys and home textile products.

Product addition: 3% for natural color and color non-woven fabrics and 5% for black non-woven fabrics.
