High temperature thermoset polymers
WebJan 24, 2024 · In this work, a thermoset resin was successfully 3D printed using SLS, and its thermal stability of printed parts after a multi-step post-curing process was investigated. … WebWhy can thermosetting polymers withstand high temperatures? Why Thermosets are the Best Temperature-Resistant Plastics Effective as the thermoplastics were, environmental factors like heat caused thermal degradation and wear. Though much lighter, the older-generation polymers could not provide the heat resistance that ceramics and metals could.
