MagPro® is a highly active magnesium oxide produced in the form of powder by carefully controlled indirect calcination of milled brucite mineral (magnesium hydroxide).

MagPro® is used as an effective acid acceptor, scorch controller, curing agent and heat stabilizer in the production of pneumatic tire inner liners and tire inner tubes based on halobutyl rubbers.

MagPro® is a key ingredient in the production of:

  • Pneumatic tire inner liners based on bromobutyl rubbers (BIIR)

  • Truck tire inner tubes based on chlorobutyl rubbers (CIIR)

Two grades are available: MagPro®150 and MagPro®170. The right choice of the appropriate grade depends on the formulation and technological parameters.
