Thermosaf polymer
Webb7 sep. 2024 · Thermosets usually are three-dimensional networked polymers in which there is a high degree of cross-linking between polymer chains. The cross-linking restricts the motion of the chains and leads to a rigid material. A simulated skeletal structure of a network polymer with a high cross-link density is shown below. Thermosets are strong … WebbThermosaf Polymer Etsy. Check out our thermosaf polymer selection for the very best in unique or custom, handmade pieces from our shops. Privacy Settings.
