Polymers have a very low electrical conductivity. As a result, friction or induction lead to accumulation of electrical charges on the surface. Electrostatic charging can cause films to stick together and destruction of electronic components. Strong electrical discharges can also lead to personal injury, fires and even explosions.

Through the application of additives, the accumulation of electrical charges can be prevented. Finding the optimal additive concentration and processing conditions is achieved by laboratory and inline measurement methods. 


  • Measurement of electrostatic charging according to DIN 53486 (upper picture)
  • Inline measurement of the charging of sheets through friction (middle figure)
  • Measurement of DC conductivity according to ASTM D257 (lower picture)
  • Locally resolved measurement of the surface charging and charge decay
  • Examination of electrical aging.
