Flame Retardant PS Masterbatch

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.

Applications for Flame Retardant PS Masterbatch

• Electronic and electrical: Flame retardant PS masterbatch is used in the production of electrical and electronic components, including housings, connectors and insulation. By providing flame resistance, they ensure the safety and reliability of these devices and reduce the risk of fire accidents.
• Building and construction: Flame retardant PS masterbatch is used in building materials such as insulation boards, roofing materials and wall cladding. It helps meet fire safety standards by reducing the spread of flames and limiting the production of smoke in the event of a fire.
• Packaging industry: Flame retardant PS masterbatch is used in packaging materials, especially for products that are prone to fire hazards. It helps enhance the fire resistance of packaging containers and reduces the risk of fire accidents during storage or transportation.
• Automotive industry: Flame retardant PS masterbatch is used in automotive interior components such as instrument panels, door trims and seat backs. It helps to enhance fire resistance and ensure passenger safety.

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.
