MVK-14 FreeForm®

High Temperature Polyimide

MVK-14 FreeForm® is a high-temperature thermosetting polyimide resin with service capability up to 316°C (204°C wet). It is accompanied by an extensive database of mechanical and thermal properties. This database, generated by the National Center for Advanced Materials Performance (NCAMP), includes over 5,000 data points and makes MVK-14 FreeForm® ready for use in virtually any application requiring a high-temperature structural composite material.

Jointly developed by Maverick and GE Aviation to replace PMR-15 and its highly toxic diamine 4,4’-methylenedianiline (MDA), MVK-14 FreeForm® contains no mutagenic or carcinogenic components. Although it is most suited for autoclave processing, its chemistry also allows for the use of compression molding.

MVK-14 FreeForm® is available as a PMR-type resin solution from Maverick Corporation, or as a prepreg from Renegade Materials Corporation.
