Webb11 juli 2024 · Hard but rubber like. The supports are almost impossible to remove because of this. It reminded me of the not so hot Tough Resin. Typically my prints have a nice rigid feel post cure. I even let them cure hours longer than normal and they stayed rubber like but did get a little harder. Webb11 aug. 2024 · Such materials are typically chemical-activated polymers and tend to degrade more rapidly than heat-activated resins. ... These stages can be described as (1) sandy, (2) stringy, (3) doughlike, (4) rubbery or elastic, and (5) stiff. During the sandy stage, little or no interaction occurs on a molecular level.
WebbThe glass transition temperature (Tg) is a phenomenon of amorphous polymers. At this temperature, polymers undergo a transition from glassy to rubbery state. Tg is an important feature of polymer behavior. It marks a region of dramatic changes in the physical and mechanical properties. Below Tg: Due to lack of mobility, the polymers are … Webb28 juli 2024 · The incorporation of TPI in epoxy resin resulted in better mechanical (i.e., fracture toughness, impact strength, tensile strength, etc.) and dielectric properties without losing its heat resistance (i.e., Tg ). Wang et al. [ 10] reported the synthesis of a toughening agent based on a hyper-branched polyester having flexible chain blocking.
