Kinel compounds

KINEL molding powders and KERIMID 601 leuninating resins dre based on a thermosetting polyimide, which cures without evolution of volatiles. KINEL compounds are transformed by compression, transfer, or extrusion molding into void-free parts, whose thermomechanical properties exceed those attainable from conventional thermoplastics or thermosets.

Additive Polyimides. Rlicjme-Poulenc s Kinel molding compound and Kerimid impregnating resin (115), Mitsubishi s BT Resins (116), and Toshiba s Imidaloy Resin (117) are based on bismaleimide (4) technology. Maleic anhydride reacts with a diamine to produce a diimide oligomer (7). Further reaction with additional diamine (Michael addition) yields polyaminobismaleimide prepolymer with terminal maleic anhydride double bonds. Cure is achieved by free-radical polymerization through the terminal double bonds. 

KINELs 5505 and 5508 are graphite filled compounds (25% and 40%, respectively). The first affords higher mechanicals, the second better wear and lubricity properties. Typical applications for KINELs 5505 emd 5508 include face seals and tiurust washers piston rings for air compressors low speed, journal bearings (speeds less than 100 fpm) ment for carbon/graphite mechanical goods. 

KINEL 5511 is an asbestos fIber/graphlte powder filled compound. Asbestos fibers impart resilience to the formulation. End-uses include valve seats seals snap-on piston rings and vanes for rotary pumps.
