I/ The THERMOTECH multifilaments stainless steel alloy based Family:

The THERMOTECH Family is a range of long life and very flexible conductive or electro heating yarns. THERMOTECH exists in version "N" or "I" insulated.





The THERMOTECH "N" (Without insulation)

, Apart its whide resistivity range, Thermotech has the following characteristics:


• Good resistivity and excellent flexibility
• Stainless, but without release or metallic particles in the environment because of the continuous filament form (for medical or clean rooms by example)
• Constant conductivity even with mechanical load variation
• Can be used as electro conductive yarns for low voltage power supply in flexible textiles structures
• Due to its continuous multifilament form, it preserves the data transfer quality, and can be therefore use in ESD or EMI applications.
• Withstanding very high temperatures , up to 600°C or even more when protected from high temperature oxydation
• Stainless, and withstanding sweat, saline water, light oxydation or washing processes
• Exellent fatigue withstanding in flexible structure,(multiple bendings or vibrations) leading to very good life time and better safety (hot spots)
• Can support very small curve radius: this means that it can be brought at the exact point were the foctionnality is needed.
• High mechanical performances
• Excellent performances in induction antenas, HF RFID applications, withstanding high number of industrial washing cycles
• Ideal for fine thermo cutting of thermoplastics or polystyrene.
• Weldable
• In many case Sewable
• Compatible within very flexible textile strutures, but also thermoplastics or composites.

The THERMOTECH "I", (in Insulated version)

The PTFE or MFA insulation type are withstanding high temperatures , Polyester insulation are generally used to withstand temperatures below 100°C

• Keeps it properties of flexibility, fatigue withstanding, contant resistivity etc...
• Can withstand temperature up to 250 to 300°C, thanks to its high performance coating (MFA or equivalent)
• Their maximum load charge is 380 Volts ; if needed a thicker insulation can be made, but minimum lauch of 20 km are required.





THERMOTECH exists in different resistivity:

THERMOTECH "IP 30" yarn: Very fine and flexible polyester insulated electro heating yarn




This yarn has been engineered to be used in knitting or weaving applications, together with as little thickness as possible.

• The THERMOTECH IP 30 is compatible, and eventually slightly dyable, with the other conventional polyester yarns that can eventually be processed together.
• Its resistivity of 30 Ohms /meter is ideal for small size structures.
• It can also eventually be inserted in our electro heating ribbons or pads as insulated power return.
• Outerwall diameter of 0,6 mm

• Some versions exists in form of sewing thread.


• NEW! A new version of THERMOTECH NC 14 yarn, called the " THERMOSEW " in 14 Ohms/meter,
  is now available for sewing of eventually embroidery with a PTFE coating

II/ The CONDUCTIB Family : fine and flexible electro conductive yarns

The CONDUCTIB yarns family are highly conductive yarns, as flexible and fine as possible, designed to bring the power or the signal to the right positionning of the fuctionnality in the structure.

They can eventually be reinforced by other elements as aramid or high tenacity filaments.

they can be made of different metals or alloy

• COPPER multifilament core
• One of the most commonly used product is the CONDUCTIB "I"insulated, with a +-0,85 mm outside diameter yarn , having a resistivity of less than 0,2 Ohms /meter.
• For higher power supply, we can also supply CONDUCTIB N 0,88 mm, with a resistivty as low as 34 Ohms/km (0,03 Ohms/m!)
• For other request as ultra fine reinforced conductive yarns: Please questions us

III/ SILVERPAM : SILVER plated or SILVER coated polyamide yarns

They can be very effective in the field of EMS SHIELDING: attenuation of more that 55 Db !
• Available in 95 dtex: resistivity of 660 Ohms/m
• Or in 250 dtex: resistivity of 198 Ohms/m
• They can also be used for electro conductive or other applications

IV/ The SPUNTECH Family :

It is characterized by :

• The spun tech family is made out of stainless steel 316L.
• An high resistvity ranging from 200 Ohms/m to 1000 Ohms/m.
• A variable conductivity in relation with several parameters :
  
  • the fiber length and fiber diameter in microns,
  • the twist or the crimping ratio,
  • The weave or braiding pattern, or more generaly how compact the structure is.
  • this specific characteristic can also lead to load measuring devices or pressure gages
• An excellent flexibility that allow very small curve radius.
• A lighter apparent density and a good softness as the yarn has a bulk effect.
• Withstanding very hig temperatures , up to 650°C in many case.
• Can withstand sweat, slight oxydation, washing processes etc.
• Also possible in blends with other fibers.

V/ Special multi-binded yarns POLYNOX:

The POLYNOX DUO yarn is a very flexible and textile compatible polyester core based yarn including an ultra fine double binder of a special electro conductive alloy withstanding washing processes and sweat.
The double electro conductive circuit is designed to prevent safety risk in antistatic or conductive applications in case of break of one of the single wires.
It can be used for antistatic purposes or electro conductive applications.

POLYNOX DUO is available in 340 dtex and has a conductivity of 400 Ohms/m

VI/ Stainless steel alloys and other metallic wires for heating or cut protection purposes:

As we work with different grades of wires for our transformation process, we can often offer you some special alloys monofilament wire for your textiles combinations: Our usual diameter range in single wires is from 30 to 200 microns (0,03mm to 0,20mm) We have some wires suitable for cut protection or antivandalism , and some for heating applications and high temperature withstanding
