Products in Polymers & Resins: Prepreg Processing

Toray EX-1510 is a highly modified two-part toughened cyanate ester resin formulated to have extremely low viscosity at room temperature. Its viscosity allows resin transfer molding (RTM) to take place without the Applications of heat to the resin. This feature provides long resin pot life and mold filling time for difficult and/or large RTM’d structures and helps increase manufacturing efficiency and reduces waste. EX-1510 displays excellent mechanical and thermal properties in addition to low moisture absorption. Finally, the material is unique in that it develops full mechanical properties from its initial 177°C (350°F) cure. A freestanding post cure increases the heat resistance.

Maverick Corporation AFR-PE-4 is a high-temperature thermosetting polyimide resin with service capability up to 343°C (260°C wet). Developed by the Air Force and commercialized by Maverick, it is intended for use in the highest temperature applications for structural composites. AFR-PE-4 does not contain the toxic diamine 4,4’-methylenedianiline (MDA) or any other mutagenic or carcinogenic components. Although it is most suited for autoclave processing, its chemistry also allows for the use of compression molding. AFR-PE-4 is available as a PMR-type resin solution from Maverick Corporation, or as a prepreg from Renegade Materials Corporation.

Maverick Corporation MVK-10 is a high‐temperature thermosetting polyimide resin with service capability up to288°C. Its low melt viscosity (300‐600 cP at 260°C) makes MVK‐10 one of a small number ofpolyimides suitable for use in resin transfer molding (RTM) processes. MVK‐10 compositesproduced produced by RTM exhibit exhibit no voids or microcracking microcracking.Originally developed by Maverick to replace PMR‐15 and its highly toxic diamine 4,4’‐methylenedianiline (MDA), MVK‐10 contains no mutagenic or carcinogenic components. Although it is most suited for RTM processing, its chemistry also allows for the use of autoclaveprocessing or compression molding. MVK‐10 is available as a PMR‐type resin solution or as apre‐imidized imidized powder from Maverick Maverick Corporation. Corporation.

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.

Toray RS-16 is a low temperature, low viscosity cure cyanate ester resin that can be used in wet winding, RTM, and VARTM processing. Its two-part construction allows easy and long-term storage while delivering excellent pot life. It is intended for lower temperature exposure with a moderate Tg requirement, and is an ideal system when used with different materials limiting the upper cure temperature. The system may also be cured using different combinations of cure/post cure temperatures and durations. 135°C (275°F) Cyanate Ester RTM Resion System
