NEW COMPOSITE RESINS(Developmental Products)
Colorless Polyimide
Industrial Summit Technology (I.S.T.) is developing polyimide resins that are transparent in the visible light range. These resins maintain the excellent thermal stability and high glass transition temperatures normally expected of polyimide resins while also possessing excellent color and clarity. This combination allows the use of polyimide resins in applications requiring good light transmission or allows pigmentation of the polyimide to produce films of any color including light colors, such as, white.
RTM
I.S.T. is developing resin that is capable of RTM processing with continuous use temperatures significantly higher than obtainable with BMI systems. We have good flow at 170-200ｰ C with an outstanding processing window of 120 minutes at 200ｰ C.The resin also has significantly improved toughness and microcrack resistance.
BMI
I.S.T. is developing a family of BMI resins with superior toughness compared to conventional BMI resins. We also have resins that have a much broader processing window for use in RTM processes and we can catalyze the cure to make fast curing systems where a wide cure window is not desirable. BMI type resins are useful in many applications including PWB, RTM, and prepreg manufacture.
Two Stage Cure Systems
I.S.T. is developing a family of two stage cure resins for prepreg and composite applications. These resins will help in volatile control during composite manufacture from prepregs. The evolution of cure volatiles from condensation cure polyimide resins is well known as a limiting factor in the use of polyimides in structural composites. The I.S.T. resins will encompass both PMR salt type systems as well as ring open oligomeric systems designed to meet needs of both adhesive and composite manufactures.
Foam
I.S.T. has a foamable polyimide technology that can be utilized to manufacture both low and high density polyimide foams. Polyimide foams can be used for thermal insulation in high temperature environments where conventional foams would not survive. High-density foams can be used in structural applications. Polyimide foams have excellent resistance to fire and are low in smoke generation making them ideal in areas where fire resistance is important.
