Description
HS-220 Anti-Hydrolysis Agent for Polyurethane TPU and Adhesives
Product Overview

High Efficiency Anti-hydrolysis Agent HS-220 Hydrolysis Stabilizer is a novel solution designed to effectively prevent the degradation of mechanical properties in polyester-based polyurethanes, including TPU, adhesives, and shoe-sole systems. It functions by capping the active carboxyl-terminated ends of polyester molecules and repairing broken polymer chains through cross-linking with carboxyl groups. This mechanism extends product service life while maintaining high mechanical strength.

Physical Properties
Chemical constitution Polycarbodiimide
Appearance Viscid yellow liquid
Melting point < 5℃
Solubility Soluble in organic solvents (e.g., methylene chloride); dissolves in water
Carbodiimide content ≥ 6%
Technical Advantages
  • High activity, reacts rapidly with carboxyl groups
  • High purity without isocyanate residue
  • Liquid formulation for easy incorporation
  • Excellent durability for wide-ranging applications
Typical Applications

HS-220 significantly enhances anti-hydrolysis resistance in polyester-based polyurethane systems including TPU, adhesives, and shoe-sole applications. It improves key properties such as:

  • Tensile strength
  • Elongation
  • Melt viscosity
  • Acid content

Recommended dosage is 0.5-2.0 phr, adjustable based on initial and desired final acid values.

HS-220 Polycarbodiimide Anti-Hydrolysis Agent for TPU
Storage and Packaging
  • Storage: Maintain in original, unopened packaging in a cool, dry place. Shelf life of at least one year under proper conditions.
  • Packaging: 25kg stacking barrels
