What is vulcanised fibre and how is it manufactured?
Vulcanised fibre is a durable, tough material characterised by high mechanical strength and environmental friendliness. It has been produced industrially since 1859 and was one of the oldest plastics used for suitcases, seals and technical components.
Production is carried out by impregnating cellulose fibres with concentrated zinc chloride solution. Paper webs are bonded by partially dissolving the fibre surface. After parchmentising and pressing out the liquid, drying follows to achieve the desired strength.
How was vulcanised fibre first discovered?
Vulcanised fibre was developed in 1859 by Thomas Taylor through the hardening of cellulose fibres with concentrated sulphuric acid or zinc chloride. This process later shaped the development of cellulose composite materials.
Which properties characterise vulcanised fibre?
Vulcanised fibre possesses high mechanical strength and is nevertheless flexible enough to be machined by bending, grinding, drilling and milling. Unlike modern plastics it is a splintering material, which must be taken into account during processing.
Where is vulcanised fibre used in industry?
- Seals: due to relative water resistance and toughness
- Grinding discs: as a backing material for high loads
- Brake linings and gears: due to high mechanical strength
- Buttons, straps and cap visors: historical fashion applications
How has the use of vulcanised fibre changed over time?
In earlier times vulcanised fibre replaced leather and rubber in suitcases and components. With new plastics the industrial importance changed. Today it is used in specialised fields that require environmental friendliness and mechanical stability.
Which modern alternatives to vulcanised fibre exist?
Vulcanised fibre has in many cases been replaced by polyamide or polycarbonate, which offer better chemical resistance. Nevertheless it remains industrially significant for environmentally friendly applications without harmful chemical residues.
Which advantages and disadvantages does vulcanised fibre offer compared to other materials?
Advantages
- High mechanical strength with stability
- Environmentally friendly, made of cellulose without synthetic plastics
- Good machinability by planing, gluing, drilling, milling
Disadvantages
- Water absorption despite relative water resistance
- Splintering behaviour requires careful processing
- Limited chemical resistance to aggressive chemicals
GOBA Takeaway
Vulcanised fibre remains an industrially significant material despite modern alternatives. Thanks to its high mechanical strength, environmental friendliness and versatility, the material is suitable for technical and industrial applications. Especially where sustainable and natural materials are required, vulcanised fibre offers a proven solution.
