Flexible heating yarns

Non insulated flexible heating wires

The resistive heating Thermotech "N" yarns family (non insulated)

The Thermotech yarns are heating metallic yarns with various conductivities : Manufactured from special stainless steel alloys micro-filaments. High fatigue and washing resistance and great flexibility.

• 3,6 ohm/m
• 4,6 ohm/m
• 7,0 ohm/m
• 9,0 ohm/m
• 14,0 ohm/m
• 30,0 ohm/m
• 60,0 ohm/m
• Constant conductivity with or without mechanical stress.
• Very good flexibility which makes small bending radius possible within textiles or composite parts.
• High fatigue resistance.
• High mechanical strength.
• High temperature resistant : up to 600°C, or even more when they are protected from oxidation (neutral environment).
• Outstanding performances for RFID applications, with a very good resistance to industrial washings.
• Suitable for cutting Polystyrene or other thermoplastic materials.
• Great resistance to sweat, oxidation, salty water and industrial washing.

The non-insulated heating Thermotech "NW" yarns (protected by a binder)

Thermotech NW wires are in fact Thermotech N wires, that are protected by an synthetic warping that allow easier subsequent textiles of RFID processes :
They remain conductive on surface and allow cross conductivity in cas of yarns crossing in weaving, knitting or embroidery. The CONDUCTIB insulated wires are available in the following resistivity range :

• Thermotech NW14 14,0 ohm/m
• Thermotech NW30 30,0 ohm/m
• Thermotech NW60 60,0 ohm/m



Thermoflex NW : stainless ultra fine micro multi-filaments threads family>

Properties:

• Protected by a thin protecting wrapping to facilitate subsequent textile transformation processes.
• Good flexibility
• High mechanical and thermal fatigue withstanding.
• Constant conductivity with or without mechanical stress.

  • 0,10 gr/m (97 tex), electrical resistivity of 68 Ohms/meter
  • 0,15 gr/m (150 tex), electrical resistivity of 45 Ohms/meter
  • 0,28 gr/m (280 tex), electrical resistivity of 30 Ohms/meter
• High mechanical strength.
• High temperature resistant : up to 600°C, or even more when they are protected from oxidation (neutral environment).
• Outstanding performances for RFID applications, with a very good resistance to industrial washings.
• Great resistance to sweat, oxidation, salty water and industrial washing.





Insulated flexible conductive or Heating yarns

THERMOTECH or CONDUCTIB flexible heating cables are most often withstanding mechanical or thermal fatigue constraints as well as washing.
Being of various cross sections, one has to chose their power transfer ability by length unit, according to requirements


The insulated heating yarns Thermotech "I" (with high temperature resistant insulation)

Properties:

• Very fine and flexible due to its micro fibers composition.
• Its relatively small thickness allows the optimization of the thickness of intermediate resin layers, and therefore the weight
• Maximum electric tension of 380 volts.
• Maximum temperature is 230°C, which can be withstood thanks to high performance coating (PTFE, MFA, PFA or equivalent).
• Other properties are similar to the ones of the Thermotech "N".



Flexible PTFE (PFA or MFA) insulated heating wires THERMOTECH cover a complementary resistivity range to the CONDUCTIB yarns; they have an excellent mechanical and thermal cycles withstanding ability :



• < CONDUCTIB insulated wires are available in the following resistivity range :

3,6 Ohms/m, 4,6 Ohms/m, 7 Ohms/m, 14 Ohms/m, 23 Ohms/m, 30 Ohms/m

Heating or conductive yarns Conductib

More conductive that THERMOTECH yarns , CONDUCTIB yarns are generally more adapted to larger heating surfaces and characterized by :

• High conductivity and therefore suitable to deal with higher currents, suitable for larger heating surfaces.
• Great flexibility.
• These yarns are designed to transfer electric power or data within the flexible structure.
• High temperature resistant (230°C) insulated version Conductib "I" available.



Flexible isolated CONDUCTIB yarns are used in conductive, deicing or heating applications on large surfaces, and more specially with high temperature , up to 230°C, constraints !


• < CONDUCTIB insulated wires are available in the following resistivity range :

0,06 Ohms/m, O,11 Ohms/m, 0,19 Ohms/m, 0,35 Ohms/m, 0,48 Ohms/m, 1,0 Ohm/m

Thermostretch: Stretchable and washable conductive heating or deicing ribbon


Thermostretch stretchable heating ribbons are similar to Condustretch but adapted to strainfull heating applications :

• "N" non insulated or "I" insulated versions exist.
• Designed for low voltage (3 to 24 volts).
• Easily inserted within garments.
  In insulated version, they will withstand washing processes while keeping their stretchability


• Quelques exemples d'applications ou l'élasticité peut etre intéressante: (réservée aus industriels transformateurs)");?>
• diving suit or heating garment
• motorbile seats, vest or car battery connected car seat heating pads
• accessories or heating jackets for animals
• medical or veterinary applications
• heating accessories for incubators or livestock, or for sprouting seedings or forcing plants
• deicing or pre-heating of pipes or industrials containers

This list is of course not exhaustive and can be extended!







Condustretch : Electro conductive stretchable connecting BUS narrow fabric, with insulated conductive wires

Stretchable conductive Narrow fabrics Condustretch are perfectly adapted to sensor connexions, data or energy transfer within washable multilayers structures or composite parts :


Standard version or Condustretch duo (input and output):

• Can help to pre-position the connections within thermoplastic flat parts which will later undergo thermoforming or press-forming.
• A version exists with several conductive yarns in parallel which makes a data bus elastic in all directions (contrary to "flex" electronics circuits).
• They are well adapted to sport or medical clothes or for robotics.
• Specific versions with controlled elongation are adapted to strain monitoring.
• Connection within washable clothes is one of the main applications of the Condustretch.

Multi conductive yarns Condustretch version:

• Bus élastique possédant un grand nombre de conducteurs ultrafins isolés idéale pour les utilisation en robotique, connectique complexe ou élements noyés dans une structure thermoplastique ou thermoformable.
• Existe également avec un espace central pour permettre une couture facile au centre.
