Right: Milliken’s Reactint colorants were designed for colouring polyurethane and other thermoset resins


squeezed and bent without being damaged during assembly. This allows them to be designed in longer pieces than solid ducts – which makes for fewer parts, easier mounting, and cost efficiency, says the company. Foam air ducts also enhance the quieter


ride of electric vehicles by reducing the mechani- cal noise of the system transmitted through the ducting (up to 5dB less than with solid ducts) and damping vibration along the duct walls. Also, there is less rattle and squeak noise from the ducting touching other components when driving, which enhances the quality of the car and comfort of passengers, says Sekisui.

Italian installation


Luigi Bandera of Italy recently installed a multi-layer sheet extrusion line – which can handle either rigid or foam PET produc- tion – at a customer in Eastern Europe. This is the fourth Bandera line commissioned by the customer. The line, which is suitable for thermoforming, Form, Fill & Seal


(FFS), printing and industrial applications, is designed for a net width of 1500mm and has a maximum output of 1500 kg/h (for rigid PET) and 750 kg/h for semi-rigid PET. It comprises: two co-rotating twin-screw extruders (2C85 52 L/D and 2C70 52 L/D); a TR90 35 L/D single-screw co-extruder; two flat dies – one of which is for foamed/semi-rigid products; a physical foam PET extrusion system; a horizontal roll stack with cross axis system for thin film and sheet processing; and systems for thick- ness control and semi-automatic cantilever winding. The line also includes an in-line PE film lamination unit – a dedicated unit that is also suitable for semi-rigid products.


including its Reactint range of colorants for polyurethane foam. Reactint colorants


are reactive polymeric liquid colorants that consist of chromo-


phores that chemically bind to polyols. The colorant


reacts into the polyurethane polymer matrix, yielding deep shades of


foam. Milliken offers a variety of primary colours for polyurethane – including blue, orange, red, yellow, violet and black – and can also formulate custom blends to make almost any colour, it says. Colour helps to give a brand identity to foam, while highlighting different characteristics such as comfort, resilience or breathability, says Milliken. At the same time, it showed its Milliguard AOX


antioxidant, which protects PU and other thermo- set polymers from oxidation and degradation. Designed to support PU flexible foamers and other producers, it improves the quality and durability of final PU parts by preventing odour-causing degradation by-products and discoloration caused by exposure to light, heat and NOx. It also helps producers to meet stringent environmental and air quality standards by reducing volatile organic compound (VOC) and outgassing condensation (FOG) emissions. “Milliken continues to develop technologies that help to improve vehicle interior air quality and meet the newest, most stringent automotive industry requirements,” notes Antoni Puig, product line manager for EMEA, for PU Colorants & Additives.


Cross-linking SABIC has added to its foam portfolio with two new dedicated LDPE grades for the cross-linked foaming process – HP0722NDF and HP2022 NDF. “These new resins are specifically designed for cross-linked foaming processes,” said Douwe van
