Bushings for Fibre Production
Effectively all glass fibres (e.g. C-glass and E-glass fibres and related types) are manufactured using glass fibre bushings of PtRh alloys. In some cases, the dispersion hardened variants of these alloys are used.
Heraeus produces glass fibre bushings to customer specification with base-plates manufactured using either pressed or welded tips, and even basalt fibre bushings.
We are pleased to cooperate with partners in optimizing the design of bushings with regard to strength and reduced precious metal costs.
Glass Fibre Bushings with welded Tips
Welded bushing base-plates have the advantage that the tip geometry can be designed more freely (e.g.: variable diameters or different internal diameters) and that the tips and the remainder of the bushing do not have to be made from identical material. In this way loadbearing parts of the bushing can be produced from materials with maximum strength and service life.
Glass Fibre Bushings with pressed Tips
Bushing base-plates with pressed tips are free from welds which could become a weak point if operating procedures are not carried out correctly.
Basalt Fibre Bushings
Heraeus also manufactures glass fiber bushings for extreme thermal and corrosive conditions such as occur in the processing of molten basalt, S-glass or mineral (insulation) glass.
