Crosslinked Density of Peroxid Cured TPV

New Paper for TSSR Meter Application

Crosslinking of the elastomer phase is the most important step during the production process, there is a lack of suitable test methods until now to determine the cross link density precisely.

A new test method, Temperature Scanning Stress Relaxation (TSSR) was examined to determine the crosslink density of the EPDM – phase. The results are in accordance with results obtained from conventional swell measurements. The advantages of TSSR measurements compared with swell measurements are quite obvious.
