Stress cracking of PBT products (ESC)
Sorun Belirtisi
PBT products crack after contacting oils and organic solvents.
Neden Analizi
PBT is sensitive to certain chemicals (such as gasoline and brake fluid) and undergoes environmental stress cracking (ESC) in the presence of stress; excessive internal stress in the product aggravates cracking.
Çözüm
Avoid contact with sensitive chemicals; fully anneal the product at 120°C/2h to reduce internal stress; select chemical-resistant grades.
Temel Çıkarım
PBT chemical resistance is limited, and environmental stress cracking requires special attention.
