| Abstract: | The polyurethane elastomer whose hardness ranges from shore A 60 -90 was synthesized using half pre-polymerization method by self-made polyester glycol and methylene diphenyl diisocyanate （MDI） as the main raw materials. The influence of the polyester polyol, hard segment content; extender amount and curing tempera- ture was investigated. The polyurethane elastomer for the use of screen printing scraping tablet had good perform-ances of excellent solvent resistance, mechanical properties, cutting machining properties, etc. |
