TECHNOLOGY | MATERIALS PEX Taking steps to recycle PEX
Sweden-based LK Systems is looking to increase circularity by developing a way to recycle PEX scrap. PEX is commonly used in the plumbing industry for its pressure resistance and flexibility but is considered difficult to recycle. “This is a major step for us in finding a sustainable solution for recycling PEX,” said Hans Bramevik, sustainability manager at LK Systems. Tests are ongoing to determine which products
BIOPLASTICS Spiral hose is biodegradable
Masterflex, which makes hose and connection systems, says it has produced a cradle-to- cradle spiral hose proto- type made from biode- gradable polymer. The breakdown of the hose is metabolised by micro-organisms and so provides nutrients for the environment. Further development steps include the selection of
environmentally friendly adhesives, additives and wire. “We show our customers and other interested parties how recycling and technical excellence go hand in hand,” said Christian Horstkötter, managing director of Masterflex. The latest prototypes are
being prepared for series production and will gradu- ally expand and transform
the existing product range. Masterflex plans to trans- form its business model into a system based on a circular economy by 2035. Its consulting and product business will gradually be realigned and expanded to include services such as systematic support for take-back, recycling and eco-certification. Andreas Bastin, CEO of the Masterflex, added: “Our vision is a circular economy for plastic hoses and connecting systems with minimised resource con- sumption. Companies can now get involved early in the development of circular hose solutions. Pilot customers can help shape individual solutions and benefit from innovative added value.” �

40 PIPE & PROFILE EXTRUSION | Spring 2025 HTPs
PPS aimed at tough
pipe uses Syensqo has launched Ryton PPS XE-5000NA, the first grade of an extrudable polyphenylene sulphide (PPS) for piping materials. The material provides a
are best suited for the material. “We see great potential in scaling up this process and using recycled PEX in various products,” said Bramevik. “It
is not only a way to reduce our footprint but also a way to create value from material that would otherwise go to waste.” �

safe, proven solution for pipes working at high temperatures and pressures. Its chemical and permeation resist- ance makes it an econom- ical and efficient choice for both traditional and emerging energy applica- tions, says the company. “There is a growing need for new piping materials solutions capable of exceeding the chemical, thermal and pressure resistance of conventional polyethylene or polyamide resins without compromis- ing processability or efficiency,” said William Sattich, principal scientist for PPS at Syensqo. “Ryton PPS XE-5000 delivers high-performance extrud- able thermoplastic compounds with a permeation resistance superior to that of com- mon piping materials.” The material is com-
mercially available worldwide. Mike O’Brien, global
marketing manager for energy at Syensqo, added: “The new grade expands the legacy of Ryton into higher perfor- mance non-metallic piping solutions.” �
