How are thermosetting plastics made
WebOnce the thermosetting polymers have been set, this means that the cross-links have been made between strands. So, even heating these polymers up again won't break the cross-links. Lesson Summary WebThe thermosetting process starts with the ‘resole’ stage, where the polymer is in an initial insoluble and fusible state, ready to be turned into the final product via plastic injection …
