Anti-hydrolysis Agents are specialty additives designed to protect susceptible polymers from degradation caused by moisture and hydrolytic reactions. These agents work by neutralizing acidic by-products, scavenging moisture, or stabilizing polymer chains to maintain material integrity throughout processing and end-use.
| Product Name | Description | Typical Dosage (%) | Form |
| Bisphenol A Bis(diphenyl phosphate) | Flame retardant with hydrolysis resistance benefits | 0.5 – 2.0 | Powder/Liquid |
| Calcium Stearate | Acid scavenger and lubricant to improve processing | 0.2 – 1.5 | Powder |
| Triacetin | Plasticizer and hydrolysis stabilizer for polymers | 0.3 – 1.0 | Liquid |
| Organotin Compounds | Catalyst and stabilizer with anti-hydrolysis effect | 0.1 – 0.6 | Liquid/Powder |
Material degradation due to moisture: Many polymers, especially polyesters, polyamides, and elastomers, are prone to hydrolysis during processing or in service, leading to reduced mechanical strength and lifespan.
Loss of performance in humid environments: Exposure to moisture causes polymer chain scission, resulting in brittleness, discoloration, and compromised dimensional stability.
Processing challenges: Hydrolysis can occur during high-temperature melt processing if residual moisture is present, leading to increased viscosity and poor product quality.
Limited existing solutions: Some current stabilizers offer partial protection but may cause side effects such as color change or poor compatibility.
