Flame Retardant Masterbatch

Flame retardant masterbatch is a premixed material. It contains a flame retardant, carrier resin, and other desired additives. It is a convenient way to add flame retardants uniformly into plastics, rubber or other polymer matrices to improve flame retardant properties, protect the environment and increase production efficiency. It is an effective alternative to traditional flame retardants and is widely used in various applications including plastic pelletizing, extrusion and injection molding.

Components of Flame Retardant Masterbatch

Flame RetardantKey chemicals in flame retardant masterbatch.Common flame retardants include bromine flame retardants (such as hexabromocyclododecane, hexabromodiphenyl ether, etc.), phosphorus flame retardants (such as triple polyphosphate, phosphate acetate, etc.), and nitrogen flame retardants (such as nitrogen-phosphorus flame retardants, nitrogen-silicon flame retardants, etc.).
Carrier ResinThe basis of flame retardant masterbatch.Common carriers include polyethylene (PE), polypropylene (PP), and acrylonitrile butadiene styrene (ABS). The choice of carrier resin depends on the type of target material and application requirements.
AdditivesEnhance the performance of the masterbatch and provide additional properties and stability.Such as plasticizers, stabilizers, antioxidants, etc.

Advantages of Flame Retardant Masterbatch

  • Flexibility: Flame retardant masterbatches can be custom-formulated to meet specific flame retardant requirements for different materials and applications.
  • Uniformity: Since the flame retardant masterbatch has been thoroughly mixed at a high concentration, it ensures uniform dispersion of the flame retardant in the material, providing consistent flame retardant properties.
  • Convenience: Flame retardant masterbatch can be added directly to the target material, avoiding the step of adding flame retardant separately during the production process and improving production efficiency.
  • Stability: Flame retardant masterbatch can provide better stability during storage and transportation, reducing volatilization and decomposition of flame retardants.

Alfa Chemistry is committed to contributing to the development of flame retardant masterbatches. Depending on the material of application, we can provide many types of flame retardant masterbatch as follows.

Selection of Flame Retardant Masterbatch

Each type of flame retardant masterbatch has its own specific polymer base application and product benefits. Choosing the right flame retardant masterbatch can help improve the flame retardancy of plastic products and ensure their safety in hazardous situations such as fire.

Customers should consider the following questions when selecting the right flame retardant masterbatch for their application:

1. What is the resin type?
2. What types of flame retardants are allowed? Halogenated? Non-halogenated?
3. What standards must be met (i.e., UL94, ASTM, or NFPA)?
4. If UL94, is it HB, V-2, V-1, V-0, 5VB, or 5VA?
5. Are the mechanical properties (i.e., tensile strength, flexural modulus, elongation, impact) important to the product?
6. Will the product be exposed to sunlight (i.e., UV stability)?

Answering these questions in advance will help us help you select the right flame retardant masterbatch for your application.

Alfa Chemistry's flame retardant products are available in a variety of chemistries, including halogenated or non-halogenated formulations, and can be customized to meet specific needs. For more product information, please contact us.
