2016 preview | Polymers and additives
Right: Velox will introduce new TPU and PEEK polymer compounds
250 materials meet reliability, durability and weight requirements while also delivering large cost savings. New PAEK grades to be shown include a special
grade for Oil & Gas industry applications offering performance in sealing systems operating over temperatures from -196 to +200°C. ❙

Wacker Chemie will launch what it claims to be the first industrial-scale 3D printer for production of parts in silicone elastomers – the ACEO Imagine Series K – as well as a number of new LSR grades. The Imagine Series K machine uses “drop on demand” printing technology developed by Wacker with an unnamed technology partner. The current system uses two print nozzles to deliver a UV-curable LSR and water soluble support resin. However, Peter Summo, Vice President Engineering Silicones, says a three nozzle system is also under development to print hard-soft or coloured combinations. The company says the machine offers a 500mm by 500mm build platform. It has not revealed specific layer and build speed data, but it is understood that a part measuring 20mm by 20mm by 20mm would take less than one hour to construct. Wacker plans to offer ACEO 3D printing as a service
Below: Additives for automotive lightweighting applications will form part of the Vertellus display
from this year and is building a technology centre – The ACEO Campus – at its main site at Burghausen in Germany. Customers will be able to upload their design and receive a printed part anywhere in the world. In the LSR materials sector, Wacker will introduce
four new products. Elastosil LR 3003/90 is a hard high modulus LSR offering a Shore A value of 90. The new grade – the company’s hardest LSR yet - is intended for production of dimensionally stable injection moulded LSR parts or as the “hard” component in a hard soft LSR combination. The new grade is transparent, offers good resistance to heat, UV and weathering, and
displays a low coefficient of friction. Elastosil LR3020/60 is a medium hardness LSR
offering enhanced steam and hydrolysis resistance intended for seal applications. It retains a compression set of 62% after 21 days in steam at 150°C. Elastosil LR3016/65 offers enhanced oil resistance and is intended for automotive sealing applications. Elastosil LR3072/50 is a high elastic recovery LSR intended for production of injection moulded radial seals and cable bushings for the electrical and electronics sector. Intended for multi-component moulding applications, it is an oil-bleeding grade that will bond to PA and PBT without use of a primer. Wacker will also show its Lumosil LR7061, which has
been developed for production of optical lenses, sensors and coupling elements. The LSR offers high transparency and a refractive index of 1.41 at all hardness values. It can withstand thermal exposure up to 200°C for extended periods and shows no yellowing. The grade processes easily and most volatiles are removed during moulding, so post curing can often be eliminated. ❙

Wipag will exhibit a kiteboard stability fin injection moulded for leading equipment producer North Kiteboarding in its second-use carbon-fibre-reinforced plastic (CRP) WIC PA6 30, the first commercial applica- tion for the grade. According to the company, CRP has long been regarded as an attractive material for its combination of stiffness and light weight but cost has limited its use in production. The company says it has been able to address this in its new carbon reinforced injection moulding compounds by using lower cost secondary carbon fibres. ❙
