Polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) are widely used thermoplastic polymers known for their excellent mechanical properties, dimensional stability, and chemical resistance. However, their flammability can pose a significant safety risk.
Flame retardancy is critical when considering the fire safety of PET and PBT products. Flame retardant additives can be incorporated into PET and PBT to enhance their flame resistance, flame spread, and exothermic properties.
Alfa Chemistry offers an extensive range of flame retardant polyterephthalate masterbatch products. Flame retardant PET masterbatch and flame retardant PBT masterbatch are concentrated mixtures of flame retardant additives dispersed in a PET or PBT carrier resin. They are specially formulated to provide flame retardancy to PET and PBT-based products while retaining their mechanical and physical properties.
Below are several flame retardant additives commonly used in flame retardant polyterephthalate masterbatch formulations. These additives work through mechanisms such as carbon formation, heat absorption, and gas phase reactions.
The specific composition and properties of flame retardant polyterephthalate 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.
