Dimensional Creep of PBT Injection-Molded Parts at High Temperature
ظاهرة المشكلة
PBT products creep under sustained load and high temperature, and the dimensions gradually change.
تحليل الأسباب
PBT creeps under load and high temperature (high-temperature creep), and the molecular chain segments gradually slip.
الحل
Use a high glass fiber content to reduce the creep rate; design the product to reduce the sustained stress level; select higher heat-resistant materials such as PPS when necessary.
الخلاصة الأساسية
PBT high-temperature creep is an important consideration for long-term applications.
