1. Product Overview & Technical Specifications

Chimassorb 119 Technical Parameters

Key Differentiators: Superior thermal stability vs. lower molecular weight HALS alternatives, optimized for polyolefin systems.

2. Key Applications & Functional Advantages

Primary Industrial Uses:

• Plastics Stabilization: UV protection for PP, HDPE, LDPE with 0.2-0.5% loading
• Coatings Protection: Prevents gloss loss in automotive clearcoats
• Agricultural Films: Extends service life by 2-3X in greenhouse covers

Performance Benefits:

• 85% retention of tensile strength after 2000h QUV exposure
• Compatibility with antioxidant packages (e.g., Irganox 1010)
• Low volatility at processing temperatures up to 280°C

3. Implementation Scenarios

Case 1: Automotive Bumper Production

Challenge: PP bumpers showing cracks after 18 months outdoor exposure
Solution: 0.35% Chimassorb 119 + 0.1% Irganox 1010
Result: Passed 5-year durability certification

Case 2: Greenhouse Film Manufacturing

Challenge: 30% film replacement annually due to UV degradation
Solution: 0.4% Chimassorb 119 in 3-layer co-extruded LDPE
Result: 22-month service life achieved
