Meta-aramid (Nomex®, Conex®, Kermel®...) or para-aramid (Kevlar®, Twaron®...) fibres are both non-melting fibres (they carbonise) used for their thermal resistance (200-250°C). However, the important difference between meta and para aramid lies in the difference in mechanical strength, para-aramid (natural yellow colour) being much more mechanically resistant.
These aramid fibres are the most widespread and make up the majority of textiles for technical uses. They are present in various fields such as: automotive (composites, tyres...), sport (ropes, composites...), defence and rescue (fire and heat protection...), transport, aeronautics and aerospace...
It should be noted that aramid fibres are not, or only with difficulty, dyed and that the colour ranges are often limited. The significant additional costs and minimum quantities of large processing operations may be required if coloured flame retardant fibres are required.
Features & Applications of Aramids
Para-aramid is, among many other applications, used in bullet-proof jackets or cut-resistant gloves.
As for meta-aramid (from raw white to yellow-orange colour), it is rather present in PPE (Personal Protective Equipment) such as motor racing suits, or firemen's equipment, alone, or combined if necessary with other fibres, such as para aramid to improve the breaking strength of the suit for example.
