NeoGraf Solutions, LLC manufactures a variety of natural and synthetic graphite powders and nanoplatelets under our Graf+® trade name. Graphite can be added to a range of polymers to enhance thermal and electrical conductivity, reduce degradation to UV radiation, and increase insulation value in foams and boards. Graphite also is an excellent lubricant.

Our Graf+ powders are available in a range of particle sizes and purities depending on the end use application. Our graphite powders are available as dry powders or compounded with polymers as masterbatches. Specialty grease and lubricants formulations are also available.

Grade Designations

Graphite Powders:

Graf+ Particle Size D50 – Purity – Graphite Type

  • Particle Size D50 varies from ~ 5µm to mm
