From early 2024 onward,  BASF  will offer its products 1,4-butanediol (BDO) and polytetrahydrofuran (PolyTHF ® ) as ‘LowPCF’ products. BASF has calculated the individual product carbon footprints (PCF) of both chemical products. The results were compared with assessments of market-wide average carbon footprints of the corresponding products of third parties. Factors Contributing to Lower Carbon Footprints: The analysis shows that due to BASF’s production setup, the PCFs of BDO and derivatives such as PolyTHF are significantly below the global average PCF of the corresponding third-party chemicals that are all produced from fossil-based raw materials. On its journey to achieve net zero CO 2  emissions by 2050, BASF is the first large chemical company to make available to its customers the individual PCFs of all its sales products. The PCF comprises the total greenhouse gas emissions that occur until the product leaves BASF’s factory gate for the customer: from the extraction of resource

  Following the studies already conducted in 2021 on the recyclability of coextruded polyethylene/ #polyamide (PE/PA) multilayer films, the independent institute cyclos-HTP GmbH has completed further extensive investigations into the recyclability of multilayer films containing polyamide 6 (PA6) and #ethylvinylalcohol (EVOH) copolymer. Compatible for Recycling in the Polyethylene Film Stream: The subjects of the studies commissioned by  #BASF SE are coextruded PE/PA6/EVOH high-barrier films as well as and laminated PA6/PE films in household packaging waste. It has now been demonstrated that these two film types are also compatible for recycling in the polyethylene. “The results show that PE film waste streams containing PA can be processed without significant adjustments to the recycling process. The certification confirms the standard market practice of PA-containing film waste already being recycled by film manufacturers today. The compatibilizer, which is incorporated additionall

Today's KNOWLEDGE Share: FDA CLEARS NOVEL CERVICAL INTERVERTEBRAL PEKK IMPLANT The U.S. Food and Drug Administration (FDA) has granted 510(k) clearance to a novel  #cervical  intervertebral body fusion system based on a new material, OXPEKK. According to its supplier, VySpine™, LLC, the new system, brand named ClariVy OsteoVy™ PEKK, provides better osseointegration than PEEK (poly-ether-ether-ketone) which has been demonstrated through in vitro and in vivo studies utilizing animal models. PEKK also allows manufacturers to create porous shapes which facilitate bone ingrowth while also providing polymer’s signature lack of radiographic interference and biocompatibility, meaning no fibrotic tissue membrane formation. According to the FDA 510(k) summary document, the ClariVy Osteo Vy™ system is indicated for “intervertebral body fusion of the spine in skeletally mature patients.” The systems are designed for “use with autogenous bone graft to facilitate fusion” and “one device may be u

Sulzer is launching a new end-to-end licensed technology – CAPSUL™ – for the continuous manufacturing of #polycaprolactone (PCL), a biodegradable polyester often used in the packaging, textile, agricultural and horticultural industries. Includes All Purification and Polymerization Steps: The CAPSUL™ solution enables optimal process performance for production of premier quality PCL grades at competitive rates. It joins Sulzer’s existing offering in renewable and #circularplastic technologies, including #polylacticacid (PLA) process technology. Sulzer Chemtech’s CAPSUL™ PCL technology includes all purification and #polymerization steps as part of a fully integrated, highly efficient and continuous process. Building on Sulzer’s expertise in separation and reaction processes, the new #biopolymer technology is highly adaptable to a broad range of industrial scales that can help drive adoption of #biodegradable and compostable PCL. Key applications for high-quality PCL include consumer

Today's KNOWLEDGE Share Innovative fibre technology could revolutionize building construction With the Texoversum, Reutlingen University has put into operation a training and innovation center for the textile industry that is unique in Europe. The almost 2,000 square meter textile-like façade of the new building also causes a sensation architecturally: It charmingly combines the innovative power of this industry with the 160-year tradition of Reutlingen as a textile location. The highlight: The components were wound from fibres that are fixed with a special plastic resin. The façade of the Texoversum is just one example of a brand new technology that could completely revolutionize the construction industry. The sophisticated structure was designed on the computer and is based on carbon fibres wound by robots. Similar to networks in nature, for example in spider webs, beetle wings or palm leaves, the fibre structures are also very lightweight, but at the same time highly resilient,

Today's KNOWLEDGE Share: Time for some really basic "LEFM" (linear elastic fracture mechanics). Fracture Mechanics essentially assumes all materials or parts do contain "defects". It is a reasonable assumption if you think about dust and all sorts of contaminants (including fillers with poor surface treatments) present in our polymer plants, compounding facilities and molding shops. If a defect is small enough, a tensile stress (steady or dynamic) will trigger a relatively stable and slow crack growth rate. This is captured by the exponent "m", i.e. the slope of the linear region II of the graph shown above. When the crack "a" reaches some critical length, the stress intensity factor K reaches the value K1c where the crack enters the unstable crack growth region, quickly leading to part failure. Some polymers are good because the stable crack growth is really slow (low value of "m"), some polymers are good because they survive despi
