Our Range of Sleeves

Aramid Fibre Sleeves, up to 400 °C

Our 100 % para-aramid fiber sleeves are made from continuous filaments that give them excellent mechanical properties. They maintain their characteristics in operating temperature up to 350 °C and can withstand a peak of 400 °C. Mainly used in the glass industry, they also have good resistance to chemicals and to abrasion.

     Applications

• Thermal insulation
• Thermal insulation of cables

Zetex^® Fibre Sleeves, up to 700 °C

Zetex^® fibreglass sleeves from Newtex are flexible and ideal insulation for wiring, electrical cables, and pipes. Available in the standard knitted version or coated with vermiculite, sleeves can withstand temperatures of up to 700 °C. The sleeves are available in different versions, diameters, and thicknesses. The ZetexPlus^® option withstand peak temperature of 1,095 °C.

     Applications

• Thermal insulation
• Insulation of pipes and exhausts
• Insulation of electrical cables and hydraulics

E-Glass Fibre Sleeves, up to 700 °C

E-glass fibre sleeves are highly flexible, thereby facilitating the insertion of cables or pipes to be insulated. These Sleeves are used for the thermal protection and electrical insulation of cables and pipes. Other versions with silicon coating, powder-coating or stainless-steel protection sheath allow to improve their mechanical and dielectric properties. E-glass fibre sleeve are available in a diameter of 12 and 60 mm.

     Applications

• Insulation of industrial ovens
• Insulation gasket

Basalt Fibres Sleeves, up to 800 °C

Basalt fibre sleeves are made from fibres of 8 to 16 μm.  They do not burn, do not melt and produce neither smoke nor toxic gases. Moreover, these products are and are environmentally friendly and recyclable. They can be used for applications involving peak temperatures up to 800 °C and operating temperatures of 700 °C. They have thermal and mechanical properties superior to those of E-glass fibres and can be used in the manufacture of composites. They are also used in the insulation of electrical cables and as thermal protection for pipes and exhausts.

Final Advanced Materials provides basalt fibre sleeves in sections ranging from 1.5 to 22 mm.

     Applications

• Thermal protection for pipes
• Thermal protection for exhausts
• Insulation of electrical cables

Silicate Fibre Sleeves, up to 1,200 °C

Silicate fibre is inorganic and contains no toxic substances. Thanks to the silicate fibre with a 9 μm diameter of their composition, silicate fibre sleeves pose no health risks during handling. Their great technical and mechanical properties make them a good alternative to ceramic fibre products and asbestos products. They are mainly used in the industry for the insulation of cables and pipes. Moreover, these sleeves are also employed for the assembly of heat protection as they can withstand peak temperatures up to 1,100 °C and operating temperatures up to 1,000 °C.

Final Advanced Materials offers silicate fibre sleeves with inner diameters ranging from 1 to 100 mm.

     Applications

• Insulation of cables
• Insulation of pipes
• Electrical insulation
• Heat protection
• Alternative to asbestos products

Biosoluble Fibre Sleeves, up to 1,200 °C

Biosoluble fibres are guaranteed asbestos and ceramic fibre-free. Their chemical composition has been adapted to eliminate the health risks associated with exposure to ceramic fibres or rock fibres for insulation. These fibres dissolve in bodily fluids such as those found in the pulmonary alveoli. They are less biopersistent, meaning they are eliminated more quickly by the body while maintaining their excellent thermal insulation and fire protection qualities.

Our biosoluble fibre products are reinforced with glass (650 °C) or refractory steel (1,050 °C). Sleeves are available in diameters from 15 to 60 mm and are available in 25 m long roll.

     Applications

• Insulation of pipes and exhausts
• Insulation of boilers
• Insulation of electrical cables

Ceramic Fibre Sleeves, up to 1,700 °C

Ceramic sleeves are primarily designed for thermal, electrical and mechanical applications subjected to extreme conditions. Composed mainly of alumina (Al₂O₃) at different percentages, ceramic products can withstand operating temperatures up to 1,400 °C and peak temperatures up to 1,500 °C. These ceramic fibre sleeves offer superior mechanical and thermal properties to other fibrous materials, such as aramid, silica, quartz or glass. They are particularly suitable for the electrical and thermal insulation as well as the protection of cables, tubes, pipes and thermocouples.

     Applications

• Thermal insulation
• Electrical insulation
• Cables, pipes and tubes protection
• Reinforcement of assembled products
• Thermocouples insulation
• Thermal shield
• Insulation gaskets
• Metal treatment at high temperature
