Polyolefins

IKV has consistently pushed the boundaries of knowledge, fostered interdisciplinary collaboration, and driven progress in the dynamic field of plastics.

Dimensional stability from injected parts can be affected by several factors like cycle conditions, polymer crystallinity, and the masterbatch’s colorant or additives.

Robotic rotational molding is an advanced technology that enables the development of unique geometries, tight tolerances to achieve part-to-part repeatability, and less waste than conventional plastic molding.

In the face of escalating environmental concerns, the efficacy of recycling systems has never been more critical. The Recycling Partnership reveals a comprehensive document “The State of Recycling: The Present and Future of Residential Recycling in the U.S. 2024” which shows some insights from the US recycling system, underscoring the necessity for a holistic approach.

Scientists at Universität Bayreuth, Germany, pioneered a low-pressure and low-temperature synthesis process to mimic LDPE’s chemical structure while enhancing its recyclability. Employing coordinative chain transfer polymerization (CCTP), they synthesized two macromonomers closely resembling commercial LDPE under mild conditions (2 bar and 70°C).

The Consultant Sphera was commissioned by the Consumer Goods Forum (CGF) to conduct a Life-Cycle Analysis on pyrolysis and related chemical recycling technologies. The analysis will be conducted on pyrolysis and related chemical recycling technologies of post-consumer mixed plastic waste to evaluate the potential environmental impacts regarding climate change and fossil resource use of circular food-grade plastics-to-plastics systems compared to fossil-based ones.

Tailored compounding for serial production and directly pelletized to the injection molding machine. Shortened supply chain (10 to 3 steps) from compounding to injection, achieving up to €1.0/kg in energy and cost savings. It accomplishes high requirements with tailored compound formulation in-house.

UK design firm Gomi believes that technology products shouldn’t become obsolete. Rather, they should be beautiful, durable, repairable and have a circular lifespan. So it is making audio speakers and power banks from recycled plastic bags and repurposed lithium batteries.

New regulations for food contact materials are getting stricter, especially for food-grade rPET. In the case of functional barriers from recycled material without prior decontamination, they could be affected and probably discontinued.

Advanced machinery that can effectively decontaminate post-consumer plastics is the key to producing rPET with exceptionally high purity. This quality is essential for FDA-approved food-grade packaging.

As scientists, we must look for the truth, but sometimes this truth can be interpreted differently depending on how our investigation scope was developed. I think this is the case of the recent study that found hundreds of thousands of nanoplastics in bottled water.

A young couple in Italy has married advanced polymer technology with an ancient Japanese art form to develop a new type of highly portable solar panel. Inspired by origami, startup firm Levante Srl is using recycled carbon fiber to create a lightweight folding panel.
