product update | Materials and applications AUTOMOTIVE Delphi eases ethanol


Delphi’s Multec 3.5 Heated Tip Port Fuel Injector picked has been developed for use on Honda’s ethanol-powered Fit and City cars in Brazil, eliminating the need for a secondary gasoline cold start system.


As ethanol does not form a


combustible vapour at low temperatures it is usually necessary to incorporate a secondary gasoline system for starting below 13˚C. The Multec device, which is

Food contact TPUs from BASF


BASF has added new food contact grades to its Elastollan portfolio of thermoplastic polyurethane elastomers (TPUs). Suitable for injection moulding and extrusion applications, the new Elastollan FC grades comply with both FDA and EU regulations governing food contact applications and are manufactured in accordance with GMP (Guidance for Good Manufacturing Practice, 2023/2006/EC). The new grades are the


latest additions to BASF’s food contact polymer portfolio. The company already offers a special food contact PBT – Ultradur B 1520 FC – for food applica- tions such as coffee capsules and food packaging. ❙ www.elastollan.de

overmoulded in DuPont’s Zytel HTN PPA, incorporates an integrated heater to prewarm the ethanol, eliminating the need for the gasoline system and saving 9kg on vehicle weight. Zytel HTN PPA was


selected for its lower melt viscosity than competing PPA grades, which is a benefit during overmoulding of the thin metal heater tube. DuPont developed a special heat-stabilized

Total has launched a range of electrically conductive carbon nanotube compounds for electrostatic discharge (ESD) applications. Available worldwide, the new Total CNT grades are


AEROSPACE Airbus opens door to PEEK


Airbus Helicopters has replaced aluminium in a bracket used on the doors of the Airbus A350-900 wide body airliner with a carbon rein- forced grade of PEEK polymer from Victrex, reducing weight and cost by around 40%. The fibre-reinforced


polymer structure of the A350’s aircraft door uses an outer skin coupled with an internal bracing structure. The injection-moulded polymer bracket connects the outer skin to points on the internal

structure to form a box-type support structure. “In terms of the standard


load case, i.e. the internal cabin pressure, this point-type joint reduces the deforma- tion on the outer skin, thereby maintaining the aerody-


namic quality of the aircraft door,” says Christian Wolf, Head of Airplane Doors Research and Technology at Airbus Helicopters. The high flow Victrex


PEEK 90HMF40 polymer is said to provide up to 100 times longer fatigue life and up to 20% greater specific strength and stiffness than aluminum 7075-T6. It also withstands the moisture that continuously accumulates inside aircraft doors. ❙ www.victrex.com

Mercedes cuts weight


Mercedes-Benz has adopted a 40% glass reinforced compound from Polykemi’s Polyfill PP HC range to replace a glass reinforced PBT in production of sun visor frames for its C-Class models. According to Swedish


compounder Polykemi, the Polyfill PP HC grade provides performance similar to glass reinforced PA or PBT but at a lower weight, which helps the car maker meet its fuel consumption and CO2 emission targets. Further savings have been


achieved through a redesign of the visor support struc- ture. Previously produced in a combination of metal and plastic, it is now a single mono-material component, which simplifies assembly and reduces cost. ❙ www.polykemi.se
