polymer product and the process of making these products which process for all the products will be essentially the same the thermosetting fluorodiepoxide polymer systems have the same fundamental characteristics i e a fluorodiepoxide polymer resin is provided which can be cured to form a crosslinked solid polymer by its mixture with a curing agent a catalyst or both the mixture then cures at a rate which is determined as a function of temperature for many systems room temperature is often sufficient for the mixture to gel or set the full cure often is completed by subjecting the mixtures to a higher temperature the curing temperature which also functions to produce the foam structure is related to the degree of cure in the gel this type of thermosetting fluorodiepoxide polymer system is to be distinguished from a thermoplastic fluoropolymer system which does not ever cure in a traditional sense it only melts when heated to a high temperature and hardens when cooled as previously noted possible problems with creating a foam with a thermoplastic system as opposed to a thermosetting system and depending on the particular application are the creation of undesirable residues resulting from the use of some of the traditional blowing agents and additives which are employed in thermoplastic fluoropolymers processes and the.
