Polyamide (PA) Stabilization Solutions

Degradation Factors & Issues

Polyamides undergo structural breakdown when subjected to environmental stressors like elevated thermal loads, moisture ingress, and oxygen exposure during processing and end-use.

Common problems include:

• Heat aging
• Hydrolysis
• Color change
• Oxidation
• Reduced impact strength
• Surface cracking
• Poor processing stability
• Long-term embrittlement

High-Performance Demands

Applications requiring continuous high operational temperatures and structural integrity demand specialized antioxidant and stabilization technologies to prevent mechanical failure and premature aging.

Thermal Oxidation Protection

Advanced antioxidant systems designed to inhibit thermal degradation during compounding and extended high-heat operation.

Hydrolysis Resistance

Specialized formulations that protect amide linkages against moisture-induced chain scission and degradation.

Mechanical Retention

Maintains tensile strength, impact resistance, and structural dimensional stability over prolonged service lifetimes.
