This high-performance PET hydrolysis stabilizer powder is designed to enhance the durability and stability of polyester-based materials. PET resins are widely used in fibers, films, packaging, and engineering plastics due to their excellent mechanical and thermal properties. However, they are highly sensitive to hydrolysis, especially under conditions of high temperature, humidity, and during melt processing.
Hydrolysis leads to ester bond cleavage, resulting in reduced molecular weight, lower intrinsic viscosity (IV), and deterioration of mechanical properties such as tensile strength and impact resistance. This degradation can significantly affect product quality, processing consistency, and long-term performance.
This product provides an efficient solution by incorporating active hydrolysis stabilization functionality into a powder form, ensuring ease of use and uniform dispersion during compounding and processing.
High-efficiency hydrolysis inhibition for PET systems
Maintains intrinsic viscosity (IV) and molecular weight
Improves mechanical strength retention after processing and aging
Powder form for easy handling and accurate dosing
Excellent compatibility with polyester resins
Enhances processing stability and reduces degradation
This PET hydrolysis stabilizer is suitable for:
PET fibers and filament yarns
PET films and sheets
Injection-molded PET parts
Packaging materials
Engineering polyester applications under humid or high-temperature conditions
The stabilizer functions by reacting with hydrolysis-generated carboxylic end groups, neutralizing their catalytic effect and suppressing further chain scission reactions. This mechanism effectively slows down molecular degradation and preserves the structural integrity of PET materials during both processing and service life.
Recommended dosage: typically 0.5% – 2.0% depending on application
Can be dry-blended with PET resin prior to extrusion or injection molding
Pre-drying of PET resin is recommended for optimal performance
Store in a cool, dry place to prevent moisture absorption. Keep packaging tightly sealed when not in use. Follow standard industrial safety guidelines during handling.
