Calendering

 

EPDM compounds calender easily, resulting in smooth and attractive surfaces and good dimensional stability. An essential condition is a medium to high roll temperature. Control of the compound viscosity and temperature is very important for maintenance of the thickness of the sheet.

In general, the following should be watched out for:

• Excessive heat loss must be avoided when the viscosity is low
• Heat build-up must be avoided when the viscosity is high.
