Description

SGL Carbon’s graphitized microballoons (with 15% sinkers) are designed as a unique and special filler material e.g. for epoxy, polyurethane or polyester resins to reduce their density and increase their strength and dimensional stability. They function as non-halogenated flame-resistant filler and support to provide greater thermal insulation. Phenolic resin microspheres are carbonized and graphitized at 2000°C (3632°F) to produce graphitized microballoons of high purity.
