Medical Polymer & Healthcare Material Stabilization Solutions

Common Challenges & Degradation

Compared with general plastics, medical polymers require exceptional purity, consistency and reliability. Even minor degradation during processing or sterilization may affect product performance and appearance.

Common challenges include:

• Polymer degradation during high-temperature processing
• Yellowing after gamma or E-beam sterilization
• Reduced mechanical strength after repeated sterilization cycles
• Color inconsistency
• Oxidative degradation during storage
• Low extractable and low volatile requirements
• Long-term dimensional stability
• Strict regulatory compliance

Standard Compliance & Reliability

Manufacturers therefore require carefully selected additive systems that provide protection while meeting demanding medical application standards.

Thermal Processing Protection

Medical polymers often undergo multiple heating cycles during extrusion, injection molding and sterilization. Our antioxidant systems effectively reduce thermal degradation and maintain polymer integrity.

Sterilization Resistance

Selected stabilization packages help polymers retain appearance and mechanical performance after Gamma, ETO or Electron Beam sterilization.

Long-Term Color Stability

Our formulations reduce yellowing and discoloration, ensuring a clean and consistent appearance for transparent and white medical products.

Low Volatility Formulation

Carefully selected additives help minimize volatile components and support demanding cleanliness requirements.
