PEX Pipe Blue is the world’s first pipe portfolio made from PEX with renewable feedstock accredited by mass balance accounting under the International Sustainability & Carbon Certification Plus (ISCC PLUS) scheme.

The pipes are the world’s first variants to be made with ISCC Plus certified bio-based PE-X.

The German Recycler Sysplast uses and develops pioneering technologies, including for the processing of surface-coated waste materials from the electronics and automotive industries. For this, the company uses high-performance melt filters from manufacturer Ettlinger.

Producing high-quality HDPE pipes and reacting flexibly to customer requirements in terms of diameter and wall thickness was the target pursued by Canadian Encoma Ltd. In line with this commitment, the industry newcomer opted for a QuickSwitch line from KraussMaffei Extrusion.

Thanks to the QuickSwitch system, Encoma is able to produce multi-layer HDPE pipes with diameters ranging between 25 and 63 mm on one and the same line.

Until now, only metal has been used for the tailgates of VW cars. In its top of the line electric model, the ID.3, Volkswagen is now using a plastic-metal composite for the first time. One of the materials used for its production is a long glass fiber-reinforced polypropylene from Celanese. The material was required to not only satisfy the mechanical demands, but also enable an attractive appearance.

The ID.3 is Volkswagen’s first car with a tailgate made partly of plastic.

Vehicle weight reduction requirements today pose great challenges not only to automotive manufacturers and suppliers but also to material producers. The materials used must cut weight while at the same time withstanding the mechanical and chemical stresses encountered in service. This can be achieved, for example, with blends of polyamide and polypropylene. These blends also offer other useful advantages.

Profiles made of rigid PVC have many advantages: they are easily extrudable, inexpensive, and with suitable additives, they exhibit good UV resistance. However, regarding its mechanical and thermal properties, PVC occasionally reaches its limits. This shortcoming can be evaded by co-extrusion with a PBT blend.

If the properties of pure PVC profiles are inadequate, PBT co-extruded versions are an option. For example, their thermal expansion and post-shrinkage when heated are lower.

Fakuma will see polymers distributor Dreyplas showcasing applications for Lubmer ultra-high molecular weight polyethylene (UHMWPE) from Mitsui Chemicals. Compared with conventional, sintered, semi-finished products, this PE offers substantial cost savings in the production of molded parts and profiles, which are characterized by very good slip properties.

When it comes to tribological applications, UHMWPE represents an alternative to engineering polymers, such as PPS, POM, PA and PBT

Before the direct extrusion of profiles made of polyvinyl chloride was developed, it was previously necessary to produce a dry blend. This process is expensive and energy-intensive and, in contrast to direct extrusion, discontinuous. The direct extrusion of PVC using planetary roller extruders promises an improvement. In addition to soft PVC, rigid PVC can also be processed in this way with a few adjustments.
