Cost-effective and sustainable production of coated parts facilitated by conductive nylon grade

The switch to a conductive grade of DuPont™ Zytel® nylon for the manufacture of lighting fixtures has helped Philips Lighting B.V. of Winterswijk (the Netherlands) achieve its aesthetic, production and sustainability requirements and has resulted in the approval of Zytel® CDV for future Philips lighting applications. Due to the nylon’s inherent conductivity, the injection-moulded end caps for the X-tendolight range of luminaires from Philips lend themselves to the same powder coating process as used for the light’s steel housing. This facilitates a closer colour match between components, eliminates the need for wet painting that contains hazardous solvents and greatly simplifies the manufacturing process.

DuPont™ Hytrel® and DuPont™ Zytel® contribute to durable and lightweight all-plastic safety shoes

Footwear and outerwear manufacturer Yakupoğlu A.S. of Ankara, Turkey, uses DuPont™ Hytrel® thermoplastic polyester elastomer and DuPont™ Zytel® nylon to replace the metal eyelets and midsole support in its new durable and lightweight non-metallic safety shoes. Hytrel® was selected for the shoe’s eyelets due to its flexibility, even at low temperatures, and its suitability for stitching to the leather upper. Zytel® was chosen for the shoe’s midsole support due to its high flexural modulus, helping to stiffen the polyurethane sole and provide more protection and comfort for the wearer. By changing to polymer components, Yakupoğlu is able to save weight and manufacturing cost, while prolonging the lifetime of its shoes.

Low-abrasion DuPont™ Vespel® thrust washers lengthen maintenance intervals in automatic gearboxes of buses

The planet wheels in Voith Turbo’s new DIWA¹ .5 automatic gearboxes rotate against low-abrasion DuPont™ Vespel® thrust washers separating them from the planet-wheel carrier. Developed for public transit buses by Voith Turbo, of Heidenheim, Germany, the thrust washers made of DuPont™ Vespel® SP21 polyimide fulfil their function virtually without abrasion, in spite of the high relative rotating speed of more than 20 000 rpm between these components. This permits extremely long maintenance intervals for the highly stressed gearboxes, which are being installed today by all major bus makers.

Cooling-water pipe of DuPont™ Zytel® resists heat, pressure and anti-freezing agent

Cooling-water pipes are exposed to high temperatures and aggressive environment. At the same time they are required to provide long-term leak resistance despite internal pressures of almost two bar. Consequently they have been traditionally manufactured from metal. As an alternative, Hutchinson of Mannheim (Germany) – in close cooperation with Volkswagen – developed a polymer pipe, made of a heat- and hydrolysis-stabilized grade of DuPont™ Zytel® nylon, and manufactured using gas-assisted injection moulding. Used in the 1.6 litre petrol engines from the Volkswagen Group, the pipe fits neatly into the available package space, facilitating the smooth flow of the cooling agent. The pipe made of Zytel® requires substantially less manufacturing expenditure than its metal counterpart, without any restrictions in terms of reliability. Thanks to its exact fit, its elasticity and the ability to integrate fixing plates and branch connections in the moulded part – rather than additional, separate parts – the pipe’s production cost is reduced considerably, while it is also approximately 50 percent lighter than its predecessor.

A new roof clip, developed by injection moulders Koves Plastic Industries Ltd. of New Zealand, is made of glass-reinforced DuPont™ Zytel® nylon, which was selected for its strength and durability. An integral part of the ‘Dimondek 630’ concealed fixed roofing profile from Dimond, the Zytel® clip replicates the strength of its metal predecessor whilst offering numerous additional benefits in terms of ease-of-use and long-term performance. Its use in the ‘Dimondek 630’ roofing system has facilitated the deployment of much longer lengths of single sheet roofing – in some cases over 60 metres – on commercial buildings in New Zealand. Koves Plastic Industries won the Bronze Award in the Building Category for its development of the Zytel® roof clip at the Plastics New Zealand Design Awards in October 2006.
