High temperature thermoset polymers
WebJan 1, 2024 · High temperature thermosetting polymers (HiT TSP) are lacking in AM material libraries. Currently, the vast majority of polymers used in AM are either thermoplastics such as ABS, nylon, PLA, and PC, or low service temperature photopolymers which cure upon exposure to UV light. WebThe stability of polymers containing fused rings appears to decrease as the number of fused chain segments increases. The effect of pendant groups depends on the nature of the group as well as the polymer to which it is bonded. (FS) Authors: Arnold, C Jr. Publication Date: Mon Jan 01 00:00:00 EST 1979.
