What is Flame-retardant Masterbatch?
When it comes to the preservation and maintenance of plastic products, safety is of utmost importance. the risk of flammability of polymer materials in warehouses is not far-fetched, and failing to observe safety precautions significantly increases the likelihood of widespread fires. Flame-retardant masterbatch can be considered a suitable solution for protecting polymer materials. As the name suggests, this masterbatch possesses flame-retardant properties and is resistant to high heat and temperatures. Items such as firefighter uniforms are among the products made from this material.
This material is obtained by combining substances such as polyethylene or polypropylene with chemical elements like phosphorus, nitrogen, and others. Naturally, using this product will lead to increased safety in the production process, cost savings, and greater durability of plastic products.

Features of Flame-retardant Masterbatch
The characteristics of flame-retardant masterbatch are not very diverse since it has a specific function; however, we will mention a few points that are worth discussing:
Reduction of fire spread
The primary feature of this material is precisely this point, which needs no further explanation. However, it’s important to note that flame-retardant masterbatch actually “reduces” the likelihood of ignition and the speed of combustion of products; it cannot necessarily turn a product into something that will never catch fire under any circumstances! While it is true that higher percentages increase the product’s resistance, ultimately it only burns more slowly. Nonetheless, this factor alone can help prevent most fires.
Environmental compatibility
Utilizing this feature in most raw materials, especially masterbatch, is common, and by adding specific chemical compounds, your product can become eco-friendly.
Application of Flame-retardant Masterbatch in Industries
Considering the points we have mentioned above, the importance of this material is undeniable. Therefore, in this section, we will address the industries that have the highest need and consumption of this material:
Automotive Industry: This material is used in the plastic parts of vehicles, especially inside, such as seats, dashboards, etc., to prevent the spread of fire in case of a vehicle fire.
Household Appliances: It is interesting to note that this material is used in the production of most household appliances like refrigerators, televisions, washing machines, etc., to ensure consumer safety.

Packaging: Goods ultimately need to be placed in their packaging and may spend a relatively long time in storage or during transportation. Since accidents can happen, the use of this material in the production of safe and standard packaging is quite beneficial.
