POWERSIL® 3525 MH silicone rubber is a one-component, ready to use, addition-curing compound that cures to an electrical insulating, highly erosion resistive silicone elastomer.


POWERSIL® 3525 MH shows fast curing in comparsion to conventional silicone rubber. Curing time is reduced by (30 … 50) % depending on the wall thickness and on the available machinery and runner system.


No peroxide decomposition products are released while curing.


  • easy demolding
  • excellent dielectric properties
  • no unpleasant smell caused by peroxides
  • no inhibition by oxygen

Spezifische Merkmale von POWERSIL® 3525 MH

  • Additionsvernetzend
  • kriechstromfest

POWERSIL® 3525 MH is especially designed for T&D applications. Because of its excellent mechanical properties POWERSIL® 3525 MH is prone for use in “cable accessories” applications.


Especially thick walled articles can take advantage of the fast curing material.

POWERSIL® 3525 MH can be easily processed like other standard silicone elastomers. Injection-molding technology is preferred.


Caution: the catalyst of the material can be desactivated if amine, sulfur or phosphorus compounds are present.


Find more information about processing in the brochures that are available at http://www.wacker.com.


The 'Best use before end' date of each batch is shown on the product label.


Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.


Permanent transportation and storage at elevated temperature leads to a partly crosslinking and makes the material unusable.
