Bismaleimide Resin

Bismaleimide is An Intermediate in the Production of Thermosetting Polyimide Resins, for Making Insulating Materials / Varnishes, Composites, Printed Circuit Boards, Potting Compounds, Etc. 

Composites, Laminates for thermal & electrical insulation by pre-pegging and Compression Molding. Compatible with Carbon, Glass, Aramid & Silica Fabrics. No volatiles during cure.

Pre-pregging grade, Composites, VARTM, High Tg. Compatible with Carbon, Glass, Aramid & Silica Fabrics. Resin lumps soluble in Acetone / Methanol. Good Shelf Life of resin solution for 2 weeks at RT. 

ABRON BR 8100 is a modified Bismaleimide based resin that is a semi-solid at RT. The viscosity of Neat Resin will be 200 – 500 cPs at 75 – 850 C and can be used for VARTM application. No volatiles are released during cure. The resin is easily soluble in Acetone and can be used as a solution for prepregging. The Shelf Life of the resin in Acetone is 2 weeks when stored at 25C. 

Fabrication of Diamond Grinding Wheels for Resin Bonded Diamond Abrasives.

Polyimides are high and low temperature resistance rendering service from –250 to +350 °C. Polyimides are intractable, infusible and insoluble polymers resulting in processing of polyimides as impracticable. Extensive research has taken place in finding out ways and means of getting processable Polyimides without jeopardizing the thermal stability and mechanical properties at extreme temperatures. Indian Space Research Organisation has put considerable amount of R & D in this line and has successfully come out with a prepolymer of polyimide which has excellent processability, stability at room temperature and with moderate cure temperatures. The composite made with this prepolymer have yielded components for space and aerospace applications. ABRON-R 750 is being manufactured by M/s. ABR ORGANICS LIMITED, with the license from Indian Space Research Organisation.

ABRON-R 750 is highly amenable for polar & filament winding technology also. The prepregs made from ABRON-R 750 has a long shelf life of 3 to 6 months at room temperature.

Tough resin system with high Tg, Hot melt & Solvent processable, No volatiles during cure. Castings, Pre-pregs, Adhesive, etc.

APPLICATIONS :

• This resin system offers excellent thermal stability & performance at elevated temperatures (> 3000C). The laminates made using ABRON BR732 system exhibit outstanding toughness & moisture resistance. This resin system can be used for the manufacture of composites where high temperature resistance & good mechanical properties at elevated temperatures are desired.
• This resin can be used for advanced composite applications by prepreging technique. The resin system can be melt processed and can be used as a high temperature structural adhesive. The prepregs can be molded into laminates that find application in printed circuit boards. The resin system is also amenable for polar & filament winding applications. ABRON BR732 System also finds application as thermal resistant coatings.
