MPET3613 is a high-performance anti-hydrolysis masterbatch specifically developed for polyethylene terephthalate (PET) systems. PET materials are widely used in fibers, films, and engineering applications, but they are susceptible to hydrolytic and thermal degradation during processing and long-term use. Moisture, heat, and acidic by-products can lead to polymer chain scission, resulting in reduced molecular weight, decreased intrinsic viscosity (IV), and deterioration of mechanical properties.
MPET3613 provides an effective and convenient solution by incorporating hydrolysis stabilization functionality into a masterbatch form. This allows for easy dosing, uniform dispersion, and consistent performance in industrial processing environments.
High-efficiency hydrolysis and acid degradation protection
Maintains intrinsic viscosity (IV) and molecular weight of PET
Improves mechanical property retention (tensile strength, impact resistance)
Masterbatch form for easy handling and precise dosing
Excellent compatibility with PET resin
Enhances processing stability and reduces degradation during extrusion
MPET3613 is suitable for a wide range of PET-based applications:
PET fibers and industrial yarns
PET films and sheets
Injection-molded PET parts
Packaging materials
Engineering polyester applications exposed to heat and humidity
MPET3613 contains functional stabilization components that interact with hydrolysis-induced degradation species such as carboxylic end groups. By neutralizing these reactive sites, it effectively suppresses chain scission reactions and slows down molecular weight reduction. This stabilization mechanism helps maintain the structural integrity and performance of PET during both processing and service life.
Recommended dosage: typically 1% – 3% depending on application requirements
Can be directly blended with virgin PET resin before extrusion or injection molding
Suitable for standard PET processing conditions
Pre-drying of PET resin is still recommended for optimal performance
Store in a dry, cool environment to prevent moisture absorption. Keep packaging sealed when not in use. Follow standard industrial safety procedures during handling and processing.
