Assuring Long-Term Durability of Plastics in Automotive Applications
Automotive plastics face extreme environmental stress over their service life-prolonged exposure to
full-spectrum sunlight (UV-visible-IR), temperature fluctuations, and moisture. These forces trigger multiple
degradation modes, including:-
- Photodegradation
- Oxidative Embrittlement
- Surface crazing and microcracking
- Gloss loss and chalking
- Yellowing and haze formation
- Structural integrity compromis
Our masterbatches are validated for real-world durability through accelerated laboratory weathering.
specifically using the Xenon Arc Weathering Chamber, a benchmark tool simulating long-term
environmental effects in weeks instead of years.
A New Standard in Xenon Weatherability Testing
Xenon Arc Weathering Testing chamber is a high-capacity, air-cooled, rotating rack xenon arc test chamber designed for advanced R&D and quality validation. It replicates the entire solar spectrum (295-800 nm) using 4200 W xenon arc lamps and optical filter systems, exposing plastic specimens to the same aging stresses found in Florida, Arizona, or other high-degradation outdoor zones.
Key Technical Capabilities:
- Specimen Capacity: Up to 164 samples (51 102 mm) or 96 samples (67 145 mm)
- Chamber Type: Fully automated rotating rack with precise irradiance and temperature control
- Irradiance Control: 340 nm, 420 nm, and TUV via patented SOLAR EYE system.
- Water Spray: Dual front and back programmable nozzles for thermal shock simulation.
- Relative Humidity Control: Precision RH management to simulate tropical or humid regions.
- Black Panel Temperature: Adjustable from 25 C to 105 C, simulating real-time surface heating
Realistic Environmental Simulation
1. Full-Spectrum Xenon Lamps
- LIGHT/YEAR xenon arc lamps provide the most realistic spectral match to sunlight.
- Lamp longevity: 8000 hours (normal irradiance) / 2000 hours (high irradiance)
- Air-cooled system: Eliminates the need for high-cost water-cooling infrastructure
2. Optical Filter Technology
Customizable filters allow simulation of specific environments or standards:-
- Daylight-Q/F/B: Outdoor conditions (ASTM Type I & II) – bumpers, trims, exterior panels
- Window Glass-Q/B/SL/SF-5: Interior exposure like dashboards or pillars
- Extended UV-Q/B/Quartz: Aggressive weathering for aerospace or under-hood components
3. Water & Humidity Stress Testing
- Deionised water spray (<0.2 S, <0.1 ppm silica)
- Dual-direction spray (front and back)
- Relative humidity control
4. Temperature Control: BP & CAT
- Black Panel Temperature (BPT): 25 C to 105 C
- Chamber Air Temperature (CAT): Maintains internal environment consistency
- Dual BP/IBP sensors: Ensure precision and ISO/SAE complian
Test Standards Supported by Xenon Arc Weathering Chamber
Automotive and polymer weathering standards supported:-
Automotive Plastics: ASTM D7869, SAE J2412 / J2527, ISO 105-B06/B10, JASO M346/M351
General Plastics: ISO 4892-2, ASTM D2565, ASTM D4459
Coatings: ASTM D6695, ISO 16474-2
Others: MIL-STD-810H, IEC 60068-2-
Correlation with Outdoor Performance
Benchmarking via real-world environments like Florida and Arizona helps ensure long-term polymer stability.
Combined with xenon arc data, this forms a strong basis for predicting durability
Masterbatches Validated Under Xenon Arc Weathering Chamber
- Exterior Body Panels: UV stabilizers, anti-yellowing pigments
- Interior Trims: Color fastness under filtered sunlight
- Under-the-hood Parts: Heat-aging resistance, gloss retention
- Optical Plastics: Haze control, IR resistance
- Silver/Effect Pigments: Gloss & texture retention
- Bumpers & Wheel Arches: Cracking & embrittlement resistance
