EXHIBITION PREVIEW | NPE 2018

decontamination of recycled PET flake materials that uses the high temperature and continuous exchange of surface of the IRD technology to remove volatiles. EFSA-approved and covered by a US FDA Letter of Non-Objection, the system is suitable for use with any extrusion line and is said to be particularly suitable for retrofit applications. The company’s PET-Booster system is targeted


at PET sheet, film and fibre production and is claimed to dry and crystallise PET within 7-10 minutes. � www.kreyenborg.com


Lehvoss North America will introduce Luvocom 1114, a high performance PEEK compound designed to provide good tribological and thermal performance. The company says the wear and friction characteristics for the new grade exhibit a low and particularly uniform curve up to 165°C (329°F), as well as an elevated heat deflection temperature. Luvocom 3F is the company’s latest offering for

extrusion-based 3D printing processes, including fused filament fabrication. The product line is dedicated to easy 3D printing and the polymers are said to offer improved layer bonding and enhanced printability. The company claims parts printed using the compounds are consistent with injectin moulded alternatives. Lehvoss will also show its Luvobatch PA BA 1001/1002 endothermic blowing agent for reinforced polyamides. It says that glass, carbon fibre and mineral reinforced PA compounds are becoming increasingly important in weight reduction applications. By using its blowing agent, density of the materials can be reduced by up to 30% with minimal loss of mechanical properties. The blowing agent helps avoid sink marks and


contraction cavities. Used as a carrier system, it can reduce or prevent the delamination in components subject to high mechanical stress that may arise during the addition of masterbatch based on polyethylene or universal carriers. � www.luvocom.com


Leistritz will show two new compounding extru- sion lines – including a purpose-designed 3Dprint filament system – and will introduce its new inline rheometer. The ZSE 18 3D filament system is built around a ZSE18 twin screw extruder equipped with loss-in- weight feeders, gear pump, die, custom air-rack for cooling and sizing of the filament, belt puller, laser gauge and winder. Rated for operation up to 425°C, the system can handle throughputs of up to 20 kg/h and has been developed with product development in mind – it offers “on-the-fly” recipe modification for rapid sampling. The system shown at NPE will be available for customer trials at the Leistritz facility at Somerville in New Jersey. Also on display will be a ZE50 MAXX twin screw unit with an extended modular barrel and screw enclosed in an insulated cover. The extended processing unit allows multiple downstream operations to be carried out including multi-stage venting, liquid injection and the incorporation of up to two of the company’s LSB 50 XX side stuffers for introduction of fillers or fibre reinforcements into the melt stream (LSB XX units offer a segment- ed screw design for maximum feeding flexibility, standard screw and barrel cooling and heating and the option of internal screw cooling). Suitable for a wide range of compounding duties, the ZSE 50 MAXX can be equipped with a 600 HP AC motor
