Aging/performance attenuation of high impact polystyrene products
Sorun Belirtisi
Product performance gradually decreases during long-term use or outdoor environments, with discoloration, embrittlement and other phenomena.
Neden Analizi
(1) Ultraviolet exposure causes material photo-aging, molecular chain breakage
(2) Thermo-oxidative aging, material oxidative degradation in high-temperature environments
(3) Contact with chemical media causes chemical aging
(4) Long-term stress on products produces fatigue aging
(5) Insufficient weather resistance of the material itself
Çözüm
(1) Add antioxidants and ultraviolet absorbers
(2) Coat the product surface with protective coating
(3) Avoid long-term exposure to ultraviolet and high-temperature environments
(4) Select material grades with good weather resistance
(5) Regularly check product condition
Temel Çıkarım
Product aging is caused by environmental factors; adding stabilizers and surface protection are key.
