Solution process

 

In the _LANXESS EP rubber solution process,

  • a catalyst is used to produce EPM or EPDM in a hydrocarbon solvent in which the polymer dissolves as it is formed
  • the viscous solution is short-stopped, washed and antioxidant is added; in the case of oil-extended grades, extender oil is added.
  • the rubber solution is coagulated and residual hydrocarbons are stripped from the rubber using steam
  • the wet rubber crumb is then dewatered and dried in the finishing segment of the process
  • the dried rubber is finally baled and packaged.
