PETG '2079851475616104452 heat deflection temperature test value low
Sorun Belirtisi
The product heat deflection temperature HDT test is lower than the nominal value, and heat resistance performance is poor.
Neden Analizi
Large internal stress reduces HDT test performance, annealing insufficient, test condition deviation.
Çözüm
Fully anneal to eliminate internal stress; execute according to standard test conditions; use high heat-resistant grades.
Temel Çıkarım
PETG HDT is affected by internal stress; annealing can increase the test value.
