Mitsubishi Chemical Group Corporation Brand

METABLEN™ is the trade name of modifiers, which have been developed originally by Mitsubishi chemical, a world prominent manufacture of methyl methacrylate resins. Adding a small quantity of METABLEN™ to various resins improves and increases their impact strength and processability, and further improves the characteristics, the appearance and the productivity of their final products. *METABLEN™ is provided by Mitsubishi Chemical Corporation, a member of the Mitsubishi Chemical Group.

Impact Modifier Technology

Core: Rubber

  • METABLEN has various materials such as acrylic, silicone/acrylic, and butadiene.
  • Toughness can be obtained by controlling rubber particle size and morphology.
  • Transparency can be achieved by controlling rubber refractive index.
  Rubber elasticity (at R.T.) Rubber elasticity (at low temp.) Whetherability
Acrylic (W-type) ++
Silicone/acrylic (S-type) ++ ++ ++
Butadiene (C, E-type) ++ ++ -

Especially silicone/acryl complex rubber has a high performance compared with the single-phase rubber particle.

Shell: Graft copolymer

  • Shell (graft) gives rubber particles compatibility to matrix resin.
  • Introduction of functional groups to shell is applicable.
