Technical Data (POLYIMILEX & EPOCROS RPS-1005)  [691 KB]


Polyimilex is maleimide-copolymer that has been debeloped by using maleimide (Imilex-P) which was first commercialized by Nippon Shokubai.
Polyimilex is non-toxic and effective in enhancing heat resistance by compounding Polyimilex with various thermoplastic resins. Polyimilex is expected to be used for developing new applications as raw material for new polymer alloys.
Polyimilex contains very low impurities because of using purified maleimide by distillation, as raw material.
