Dub-Masterplast G+ is a family of thermoplastic masterbatches of pristine graphene nanoplatelets (G+). This material is produced according to customer need in terms of polymer type, G+ grade and concentration.

Dub-Masterplast G+ products, being in granular form, dramatically facilitate the incorporation of graphene nanoplatelets into the final compound and ensure a faster dispersion and distribution compared with traditional fillers. The typical concentration of G+ ranges from 10 to 20 wt%.

Matrices already available and developed, using Dub-Masterplast G+, for specific applications include:

  • polyammide6 (PA6)
  • polycarbonate (PC)
  • polypropylene (PP)
  • polyethylene terephthalate (PET)

Directa Plus is able to create and produce tailor-made masterbatches to satisfy clients’ specific requirements.
