Graphitized filler for polymer composite materials and syntactic foams
Whether it is about producing temperature-resistant, particularly lightweight composite materials or syntactic foams: SIGRATHERM non-reactive graphitized microballoons make the difference.
The hollow microspheres with an average diameter of 51 microns are a unique and special filler material, e.g. for epoxy, phenolic, polyurethane and polyester resins. SGL Carbon’s graphitized microballoons allow for significantly reduction of the resins’ density and at the same time for increase of strength and dimensional stability.
