Dingemans Delft University of Technology, Faculty. thermosets are their high melt viscosity and processing temperature. Microstructure. " Weld it with a clear polycarbonate rod. Cheng and co-workers report in rigid rod polyimides that the beta transition is caused by the noncoordinated movement of the diamine groups although the link to physical properties was not. g. Phenolics, also known as Thermosets, are extremely versatile and machinable plastics that deliver unique properties by combining resins. The monomers were endcapped with maleimide, nadimide, and methylnadimide functionalities. The EDC process was carried out by a Sodick AQ35L die-sinker EDM machine. 2. The curing step is when thermoplastics and thermosets really diverge from one another. Thermoforming – Films of thermoplastic are heated to soften the film, and then the soft film is pulled by vacuum or pushed by pressure to conform to a mold or pressed with a plug into a mold. 2. APPENDIX H SPECIFICATIONS The following is the index of material specifications. The Injectiweld has interchangeable tips and. Thermoset plastics maintain their stability in all environments and temperatures. It is then smoothed and the hole re-drilled.
