Exhibitors at wire 2024

Bow Technology

At wire 2024, the company will present its Helicord® technology for surface processing of wire and cable, such as welding wire finishing or removal of misprints from cable. It will also show its Helilub® technology for precision, solvent-free lubrication of magnet wire, and the Labtech range of products for production-related analysis and measuring technology. The Helicord and Helilub principle is based on friction between a fast-moving wire and a textile cord or yarn wound around a wire, strand or insulated cable multiple times, moving slowly under push-pull-controlled conditions, creating a multiple 360° contact between the constantly renewed cleaning cord and the wire. Friction power on the wire increases linearly with the wire speed. This means the friction energy per wire surface unit, and thus also efficiency, is independent of the wire speed: Helicord can be run at drawing speeds. The use of small amounts of liquid, such as water-based tensides, organic solvents, oil or a variety of dispersions, may be desirable or even required for both cleaning and coating processes, depending on the application. For the welding wire industry, a variety of welding wire finishing cords combine the properties of solid finishing materials with the precision of Helicord coating. Other applications include cleaning insulated cable; applying primers or dispersions such as water- or solvent based PTFE dispersions to bare wire or insulated cable; and removing inkjet misprints from cable.

Aztech provides a full range of calcium-, sodium- and potassium stearate-based drawing powders, RP oil, drawing oils, vanishing oils and pre-coats, and a complete line of AZWipe spiral brushes. The company has manufacturing and distribution capabilities in the USA, Colombia, India and Korea.

Aztech Lubricants LLC www.aztechlube.com Benvic SAS

11 A77 In the challenging role of being a compounder for the cable market, Benvic is continuously developing new products and capabilities. In a changing market, the company reinforces its halogen-free, flame-retardant (HFFR) Linkflex range – highly processable HFFR compounds first launched in 2020. Range extensions in 2023 included fibre optic cable with optimal flame retardancy; adaptation to local markets for low-voltage based on thermoplastic and cross-linked compounds; and 1 kV cable offering compliance to various standards, with innovation to remove the bedding operation. Continuous improvement programmes are also based on low-cost solutions that keep the main performance. Colour options based on market standards will be an option available in 2024. A focus will also be on medium- and high voltage cables. This segment is facing continuous development with new solutions, and Benvic has an upcoming range later in the year. In addition to HFFR compounds, Benvic is present in PVC and thermoplastic elastomers, which give extensive compounding capabilities for different applications such as electromobility. By creating original solutions for recy cled content integration, care for en vironmental performance is part of Benvic’s development.
