The Problem: During high-temperature processing and high-humidity applications, PET polyester materials suffer from:
Viscosity Drop: Increase in terminal carboxyl groups leads to molecular weight decay.
Embrittlement: Autocatalytic hydrolysis causes a sudden drop in mechanical strength.
Processing Issues: Powdered additives cause dust pollution and uneven dispersion.
The Solution: Bio-SAH™ MPET3613 provides a one-stop anti-hydrolysis solution:
Viscosity Stabilization: Effectively reduces melt viscosity attenuation during spinning and extrusion.
Precision Capping: Highly active carbodiimide groups precisely seal carboxyl ends, fundamentally blocking the hydrolysis chain reaction.
Enhanced Lifespan: Extends the service life of PET products by 3 to 5 times under harsh outdoor conditions.
Seamless Integration: The PET-homologous carrier ensures perfect compatibility without agglomeration or precipitation.
Easy Dosing: Uniform granular form allows for precise automated feeding, eliminating dust pollution.
High Thermal Stability: Stable melting point (250-260°C) ensures no decomposition during high-temperature melt-blending or spinning.
Mechanical Recovery: Stabilizes the initial mechanical properties and restores molecular weight to damaged polyester chains.
Batch Consistency: Manufactured under strict ISO9001 quality control for reliable large-scale production.
PET Monofilaments: Filter fabrics, industrial meshes, brush filaments, and grass trimmer lines.
Polyester Fibers: High-tenacity industrial yarns, textile fibers, and non-woven fabrics.
Solar Energy: PET base films for photovoltaic (PV) backsheets.
Engineering Plastics: PET/PBT injection molded parts, bottle flakes, and automotive interiors.
Packaging Materials: Industrial strapping, high-strength packing belts, and food-grade containers.
Packaging: 25KG moisture-proof paper-plastic composite bags or customized drums.
Storage: Store in a cool, dry, and ventilated environment. Keep away from direct sunlight and moisture.
Shelf Life: ≥12 months when stored in original sealed packaging.
