Filler boosts gas barrier

Comments Email Print

A new filler from Lehmann & Voss. & Co. improves gas barrier and is lighter than traditional mineral fillers and carbon black.

Luvomaxx CF materials comprise naturally occurring carbon and cryptocrystalline silica with specific gravities ranging from 1.3 to 1.7. Lehmann of Hamburg, Germany, also claims the products create little dust during dispersion and their low specific gravity aids mixing.

The fillers have platelet structures with average particle size of 3.5 to 6.5 micrometers, a boon to gas barrier properties. Lehmann says Luvomaxx CF is suited to injection molding and rubber processing.
