SHOW PREVIEW | NPE 2018


plastics extrusion. At the show, Neutrex will discuss the latest compounds that speed up colour changes, eliminate contamination, reduce rejects, and decrease downtime. They are engineered to clean the barrel, screw and other parts of the system. It will also feature a number of seminars on its


stand, including one from consulting engineer Allan Griff, called ‘The Ten (11) Key Principles of Extrusion’. Purgex grades comprise active ingredients with


Above: MTI’s heating/ cooling mixer combination Flex-line will be delivered to a customer after the show


The M2000/K8000 unit features an 8,000 litre cooling vessel and is over 7m (23ft) long and nearly 5m (16.5ft) high.


Installing the system – the largest heating/ cooling mixer combination MTI has ever supplied to the USA – will almost double mixing capacity at the customer’s site. Burkhard Wulf, area sales manager at MTI, said:


“We have seen a trend towards increasing produc- tion volumes in the US market for some time.” The M2000/K8000 is a heating/cooling mixer

combination for a typical batch volume of 950kg (around 2,100lbs). It can provide more than 7,500kg (16,600lbs) of mixed material per hour. Designed on a modular principle, these mixers can be put to use in most applications because their sizes, drive units and equipment options can be individually configured. Northern Pipe had used an MTI heating/ cooling mixer combination for around 30 years, and installed a new system in 2014. “At that time, it was not possible to install a larger system as we had used the available floor space already,” said Derek Hanson, vice president of engineering at Northern Pipe. The company is now on the verge of installing the new system, which has a much higher capacity. “We are now eagerly awaiting its delivery and commissioning since this will overcome a real bottleneck in our plans to expand production capacity,” said Hanson. � www.mti-mixer.de

a resin carrier and are engineered to clean thor- oughly and quickly to maximize colour/resin change turnaround and reduce scrap, says the company. Most are designed for versatility and are effective on a broad range of resins and multiple production methods. � www.purgexonline.com


Orion Engineered Carbons will highlight a range of carbon blacks at NPE, including its Printex Zeta A beads for pressure pipe. The beads are designed for use in PE100 and PE4710 pipe for gas and water distribution. Their high chemical purity and physical cleanliness reduce taste and odour effects, says the company. Low compound moisture absorption and high


microscopic dispersion performance ensure a smooth, defect-free pipe. In addition, they provide high UV protection for long-term stability. It will also show its Arosperse 5-183A beads, a


soft-beaded Furnace Black for use in semi-conduc- tive insulation shields for medium-voltage cables, with low sulphur impurities and low sieve residues. The product can also be used in potable water pipe, where high purity, cleanliness and high dispersion extend service life. � www.orioncarbons.com


PSI-Polymer Systems will introduce a new melt filtration system at NPE. Its ILF-55 in-line filtration system is a discontinuous, high capacity filter aimed at long batch production runs where the extrusion process cannot be disturbed – and where ultra-high filtration levels must be maintained continuously. ILF filters are typically used where


screen changers are either too large for the application or cannot satisfy the filtration level requirement without incurring an unacceptable pressure drop. ILF vessels can be fixed in line or


interchangeable and are supplied with www.pipeandprofile.com
