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