We are making researchs on plastic rolls for super calender. The plastic roll has been run on soft nip calender and super calender for thermosenstive paper. The plastic roll has been studied on several commercial super calender, but there are still some unsolved problems. (1) High pressure resistance (2) High temperature resistance (3) Crack by paper wrapping (4) Accumulation on the roll surface We have developed a plastic roll, called "Elaglass ZE", that might be a solution to these problems. Elaglass ZE shows the following good caracteristics : The glass transition temperature is 180°C. High pressure resistance is more than 350 KN/m. Elaglass ZE has been already running on several commercial super calender, and excellent results could be obtained.
