Thermoforming involves the heating of medical polymer film above their softening point such that it conforms to a male or female mold cavity. Incorporation of vacuum pressure to the heated film, known as vacuum forming, ensures conformity to the mold configuration. In comparison to other processing methods, molds used for thermoforming and vacuum forming are economical due to the low pressure used in the process and limited mold complexity.
Polyzen has in-house capabilities to produce films and molds used for thermoforming and vacuum forming. Our production equipment is capable of forming thermoplastic polyurethanes (TPUs), polyamides, ethylene-vinyl acetate (EVA), polyolefins, polyvinylidene fluoride (PVDF), polyvinyl chloride (PVC), engineering thermoplastics, and laminated films.
