Antioxidants for Polyurethane Application
Polyurethanes offer a wide range of performance characteristics and the use of suitable stabilizers can extend the service life of polyurethane products.
Autoxidation may be initiated by high energy radiation (UV light), heat, catalyst residues, mechanical stress, or through reaction with other impurities.
UHS-678 is low phenol content grade. It is an anti-yellowing stabilizing system that provides long-term heat stability by preventing thermo-oxidative degradation during processing and service life. It will not last hydrolyzed phenol, so the total phenol content may be less than 100ppm. It is suitable to applied in many polymers like TPU , PUR , rubbers or other plastic.
-Appearance:Transparent liquid
-Specific Gravity (25℃) : 0.097~0.098 g/cm3
-Viscosity(25℃): 250~310 mPa.s
-Acid Value(mg KOH/g) : <0.5
-Flash point: >50℃
-Boiling Point : >200℃
