Overview: High Temperature Sewing Threads

Final Advanced Materials offers high temperature resistant sewing threads up to 1,700 °C. These products are mainly used for the manufacture of thermal protections and protective clothing. They are coated with PTFE to facilitate sewing. This coating disappears during application from 150 °C without altering the qualities of the thread.

Applications of Sewing Threads

• Protective clothing
• Airbags
• Ballistics (bullet-proof vests)
• Composite materials
• Air dust extraction filters (hot gas filtration)
• Tires (reinforcement)
• Gaskets
• Webbing

Our Range of Sewing Threads

Aramid Sewing Threads, up to 425 °C

Final Advanced Materials presents two different types of products in polyamides:

• Para-aramids: used in many fields with high-tech applications, they are mainly known under the brand name Kevlar^®, from DuPont, and are used for their superior mechanical properties.

• Meta-aramids: these are mainly recognised for their thermal and chemical characteristics and are known under the the brand name Nomex^®, from DuPont. They are mainly used in the fields of technical textiles and protective clothing.

Kevlar^® Threads

Kevlar^® or para-aramid threads are heat resistant, self-extinguishing and do not melt. They can withstand continuous temperatures of around 170 °C. Beyond this, the mechanical and dimensional characteristics decrease (slow carbonisation of the polymer) up to their decomposition temperature of 425 °C.

Applications

• Ballistics (bullet-proof vests)
  
• Safety shoes
• Protective clothing: against Heat, Flame and Cuts (gloves, loggers' trousers)
• Composite materials
• Airbags
• Air dust extraction filters (hot gas filtration)
• Tires (reinforcement)

Nomex^® Threads

Nomex^® meta-aramid threads from DuPont are heat resistant, self-extinguishing and do not melt. They can withstand continuous temperatures of around 220 °C. Beyond this, the mechanical and dimensional characteristics decrease (slow carbonisation of the polymer) up to their decomposition temperature of 370 °C. The threads with the most beneficial properties are those containing continuous filaments. Their resistance to rupture and abrasion is far superior to other types of thread.

Applications

• Heat and flame-resistant clothing, textiles and stitching
• Safety shoes
• Protective gloves
• Aircraft seats
• Airbags

Glass Fibre Sewing Threads, up to 700 °C

E-glass fibre is a high-quality material that offers heat resistance up to 500 °C (continuous temperature). We offer sewing threads in glass fibres for the manufacture of thermal protection or thermal, dielectric or chemical insulation solutions.

Applications

• Clothing
• Weaving
• Braiding

Ceramic Fibres Sewing Threads, up to 1 700 °C

Alumina fibres threads are primarily designed for thermal, electrical and mechanical applications subjected to extreme conditions. Composed mainly of Al₂O₃ at different percentages. They are resistant to continuous temperatures up to 1,370 °C. Their excellent resistance to abrasion and mechanical stress makes them particularly suitable for sewing.

Applications

• Making fire protections
• Manufacture of dielectric and chemical insulators
