1. Product Overview & Specifications

Irganox 1141 (CAS 134701-20-5) is a high-performance phenolic antioxidant widely used in polymer stabilization. It excels in protecting materials from thermal degradation and oxidative stress.

Key Specifications:

2. Key Applications & Benefits

Primary Uses:

• Polymer Stabilization: Prevents thermal degradation in polyolefins (PP, PE), PVC, and engineering plastics.
• Rubber Products: Enhances aging resistance in tires, seals, and industrial rubber.
• Lubricants: Extends oil life by reducing oxidation at high temperatures.

Advantages:

• Superior migration resistance
• Low volatility at high temps
• Synergistic with UV stabilizers

3. Usage Guidelines

Recommended Dosage:

• 0.1-0.5% for polyolefins
• 0.2-1.0% for rubber compounds

Processing Tips:

1. Pre-dry at 60°C for 2 hours
2. Mix with polymer melt uniformly
3. Process below 300°C to avoid decomposition

4. Case Studies

Case 1: Automotive PP Components

A Tier 1 supplier achieved 40% longer part lifespan by adding 0.3% Irganox 1141 to dashboards and bumpers.

Case 2: Food Packaging Film

0.2% concentration prevented yellowing in BOPP films after 1,200 hours of UV exposure.

5. Client Success Stories
