general rules for thermoset processing are analyzed considering pot life, processing window, and manufacturing methods involving low energy consumption and enabling rapid processing. brief survey of vitrimers and advanced materials based on thermosets with specific properties such as recyclability, self-healing, or shape memory is provided.feb 27, 2019 processing thermoset polymers usually involve three stages. the first stage is commonly referred to as resole where during this stage the resin is an insoluble and fusible condition or state. In the second stage, the thermosets are only partly soluble, and they tend to display the characteristics of a thermoplastic where the changes are reversible.thermoplastics and thermosetting polymers are types of plastic that undergo different production processes and yield a variety of properties depending on the constituent materials and production method. the terms thermoplastic and thermoset stand for how a material is or can be processed under a changed temperature the main physical difference is how they respond to high temperatures.
