High-Temperature Resistant PA6/PA66 for Automotive Engine Compartments: Analysis of Heat Deflection Temperature and Long-Term Creep Performance
Under-hood temperatures often exceed 120°C, requiring PA6/PA66 parts to resist both heat deflection and creep under sustained loads. Glass fiber reinforcement, thermal stabilization, and crystallinity control determine HDT, while molecular weight, fiber orientation, and annealing directly affect long-term creep. This article analyzes the synergistic technical path from formulation to structural design.
