Polystyrene (PS), a widely used thermoplastic, is a versatile polymer composed of styrene monomers. It has desirable properties such as low cost, lightweight and excellent processability. However, its flammability has been an issue in applications where fire safety is critical.
To meet this challenge, flame retardant PS masterbatch has emerged as an effective solution. Alfa Chemistry offers a wide range of flame retardant PS masterbatch products. The masterbatch is produced through a blending process in which flame retardant additives are homogeneously mixed with PS resin in precise proportions to enhance its flame retardancy, flame spread and exothermic properties.
Commonly used additives are brominated flame retardants (tetrabromobisphenol A or polybrominated diphenyl ethers), phosphorus flame retardants, antimony trioxide, etc. These additives work by forming charcoal, absorbing carbon, and absorbing heat. These additives work through mechanisms such as charring, heat absorption and gas phase reactions. By interrupting the combustion process, they help to reduce the risk of fire spread and limit the release of toxic gases.
The specific composition and properties of flame retardant PS masterbatch may vary depending on the level of flame retardancy required and the target application. It is recommended to consult with our technical team to select the right masterbatch for a specific application, taking into account regulatory requirements and performance criteria.
