Engineered Graphite Additives Enhance Performance in a Wide Variety of Applications

NeoGraf Solutions, LLC offers a variety of masterbatches incorporating its Graf-X™ graphene nanoplatelets, Graf+® graphite powder, and GrafGuard® expandable graphite additives.

Why Graf-M™ Graphite Masterbatches

Graphene, graphite, and expandable graphite additives can be added to polymers to boost their electrical, thermal, mechanical and fire-retardant properties. The use of masterbatches is favored by customers who prefer the convenience of handling pellets rather than powders in their manufacturing processes.

Graf-M™ Product Portfolio

Material grades have been developed for the insulation board market. Properties of the three grades are available at TDS618.

  • Graf-M EPS (01) for expanded polystyrene (EPS) insulation boards
  • Graf-M XPS (01) for extruded polystyrene (XPS) insulation boards
  • Graf-M XPS (02) for extruded polystyrene (XPS) insulation boards

Fire retardant (FR) grades have been developed for the polyolefin foam and thermoplastic markets, all using an LDPE carrier and 50% expandable graphite loading.

Properties of the four FR grades are available at TDS617.

The nomenclature is Graf-M FR (resin type) (Onset Temperature (°C)-Mesh Size)

  • Graf-M FR (resin) (Grade)
  • Graf-M FR (LDPE) (200-100)
  • Graf-M FR (LDPE) (210-200)
  • Graf-M FR (LDPE) (250-50)
  • Graf-M FR (LDPE) (280-50)

Other formulations can be available on request.


Graf-M™ masterbatches are used in the building and construction, transportation, automotive and bedding industries

  • In the manufacture of insulation boards (“Grey Board”) to increase their insulation value and reduce degradation to UV radiation.  An increase in insulation value of ~ 20% can be accomplished with a graphite loading level of ~ 2-6 %.
  • In the manufacture of polyolefin foams and thermoplastics to increase fire retardancy
