- Extending service life of adhesives and rubber products
- Protecting engineering plastics (PA, POM) from UV degradation
- Enhancing durability of lubricants and industrial oils
3. Directrices de uso
Dosis recomendada:
- Polymers: 0.1% - 0.5% by weight
- Rubber: 0.2% - 1.0% by weight
- Lubricants: 0.05% - 0.3% by weight
Processing Instructions:
- Pre-dry material at 60°C for 2 hours (if hygroscopic)
- Mix evenly with base material during compounding
- Process below 300°C to prevent thermal decomposition
4. Casos prácticos
Case Study 1: PP Fiber Stabilization
A polypropylene fiber manufacturer achieved 40% longer UV resistance by adding 0.3% Antioxidant 5067 during extrusion, maintaining tensile strength after 1,000 hours of accelerated aging tests.
Case Study 2: Automotive Rubber Seals
Incorporating 0.8% Antioxidant 5067 in EPDM rubber seals reduced compression set by 25% while maintaining flexibility at -40°C to 150°C operating temperatures.
