Aging/Performance Decay of acrylonitrile-butadiene-styrene copolymer Products
Problem Phenomenon
The performance of the product gradually declines during long-term use or in outdoor environments, with phenomena such as discoloration and embrittlement.
Cause Analysis
（1）Ultraviolet radiation causes photo-aging of the material and molecular chain breakage
（2）Thermal-oxidative aging, the material oxidizes and degrades in high-temperature environments
（3）Contact with chemical media causes chemical aging
（4）The product is stressed for a long time, producing fatigue aging
（5）The weather resistance of the material itself is insufficient
Solution
（1）Add antioxidants and ultraviolet absorbers
（2）Coat the product surface with a protective coating
（3）Avoid long-term exposure to ultraviolet and high-temperature environments
（4）Select material grades with good weather resistance
（5）Regularly check the product status
Key Takeaway
Product aging is caused by environmental factors, and adding stabilizers and surface protection is the key.
