products & developments Bio-based corrugated cable protection tubing

Reiku’s corrugated cable protection tubing made from renewably sourced plastic is an environmentally friendly alternative to products made from conventional oil-based materials, and is also claimed to offer advantages in application. Under a continuous series of bending cycles, typical for many industrial robots, the product has the highest service life of all corrugated cable protection tubing in Reiku’s portfolio. Sales manager Peter Sailer commented, “In internal trials, corrugated bio-based tubing with a nominal width of 70mm remained free of damage even after 16 million cycles in the flexibility test, which corresponds in practice to a service life of around three years. With the development of this corrugated tubing product, Reiku has demonstrated that top-performance cable protection is ensured, also in view of dwindling oil reserves.” The behaviour of the tubing under dynamic stress is attributed to the special properties of the material used to produce it. The corrugated cable protection tubing, which is available in nominal widths of 12 to 70mm, is made from halogen-free flame- retardant polyamide 11 (PA11). This bio-based engineering plastic combines mechanical properties under static and dynamic load with high temperature and chemical resistance. It is also abrasion- resistant.

Corrugated cable protection tubing from Reiku has been used by a supplier of automated painting systems

Because it is produced primarily on the basis of castor oil obtained from the seeds of the tropical castor oil plant, it has a better CO 2 balance than polyamides based on fossil energy sources. A German supplier of automated painting plants and paint application systems has been using the bio-based corrugated tubing for its latest painting robots. The tubing is mounted on the outside of the robot arm, and protects the cable and wiring packages that supply the head of the robot and its

atomisers with control signals, energy, air, coating material and rinse media.

The robots normally operate in three- shift rotas and continuously perform fast, three-dimensional movements with high axis speeds and accelerations. After more than 12 months of continuous industrial application, and having installed around 1,000m of corrugated bio-based cable protection tubing, the company has not had a single report of failure or a single complaint. Reiku corrugated cable protection tubing is available in a variety of types to satisfy specific application requirements. PA6 and thermoplastic polyester (TPE) are suitable for general machine, apparatus and vehicle construction. Corrugated tubing of thermoplastic polyurethane (TPU) will also resist the high dynamic stresses that are typical for the movements of industrial robots. PA12 additionally complies with the demand in rough environments for high static and dynamic load stress resistance at particularly low temperatures, while the PA11 bio-based types combine a maxi- mum of dynamic load resistance, UV, chemical and temperature resistance.
