Graf+® graphite powders 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. NeoGraf’s Graf+ natural and synthetic graphite powders and graphene nanoplatelets (GNP’s) are available in a range of particle sizes, BET surface areas, Scott densities, and purities depending on the end use application.
Graf+ graphite powders and masterbatches are used in a broad range of applications including additives in batteries, foams, greases, extruded polystyrene insulation boards, fuel cells, paints, adhesives, chemical/mechanical polishing, coatings and roofing products. Primary markets are building and construction, energy storage, semiconductors, lubricants and coatings.
Graf+ synthetic and natural graphite powder additives enhance performance in a range of products and applications:
In extruded polystyrene (XPS) foam boards expanded graphite powders provide multiple functions. Addition of as little as 1-3% graphite:
In battery applications (alkaline, li-ion, lead acid) both natural and expanded natural graphite powders are commonly used as conductive additives, providing excellent thermal and electrical conductivity, chemical stability and high purity. Expanded graphite, by virtue of its higher surface area, is used where the goal is to maximize the active material content.
In thread sealant pastes graphite powders can be used for long life sealing performance even under the most severe temperature and pressure conditions.
In polymers graphite additives increase electrical and thermal conductivity for anti-static, static dissipative and conducting polymer applications.
NeoGraf’s graphite powders are available as dry powders or compounded with polymers as black masterbatches. Specialty grease and lubricants formulations are also available. Our manufacturing capabilities allow us to also offer customizable solutions to meet your unique application requirements.
Graf+ graphite powders are offered as:
All Graf+ Graphite Powders are available with a particle size range of ~ 5-25 µm with coarser sieved fractions available on request. Graphite purity varies from < 95% Carbon to > 99.9% Carbon. Our powders can be made in masterbatches tailored for use in Polystyrene (PS), Low-Density Polyethylene (LDPE) or Polyethylene Terephthalate (PET) applications. They can also be combined with mineral oil and petrolatum to produce pastes.
