components supplier Klober has introduced several ways to cut plastic consumption
applications, including many in construction. The line can make honeycomb cores in widths up to 1.2m. At the same time, the design of the line allows other thermoplastics – such as polycarbon- ate and polyamide – to be processed. The rPET honeycomb cores are made of up to 100% post-consumer and post-industrial recyclate. They can be laminated with conventional fibre- reinforced plastics (FRPs) to make sandwich panels and parts. In combination with PET or PET compos- ite skins, they offer recyclable, sustainable and lightweight panels, said the company. “Recognising the global problem of agglomer-
ated PET waste, we decided to optimise the technology towards rPET materials,” said Tomasz Czarnecki, chief operations officer at EconCore. EconCore recently presented the rPET honey- comb technology at K2022. The company – which comprises EconCore in Belgium and ThermHex Waben in Germany – main-
portfolio in early 2023. Celplast is made using a semi-Celuka process – which prevents cell formation on the surface of the molten material through an immediate reduction in temperature. It produces a compact, smooth and even surface. The result is a foamed PVC sheet that is lightweight and strong – offering good surface quality and low thickness tolerance across the entire width. This makes it suitable for design and construction applications.
Insulation board Trinseo has commercialised its Styron X-Tech 4660 polystyrene resins for extruded polystyrene (XPS). The material – based on patented cross-linked
polystyrene technology – allows customers in the building and construction industry to reduce material consumption in foam insulation boards. “Customers can lower foam insulation board density without compromising compression strength,” said Alain Minelli, business manager of copolymers and polystyrene. With XPS insulation board, the closed cell foam structure is responsible for providing long-term
