Niagara Bottling is breathing new life into California's recycling infrastructure with the acquisition of a first-of-its-kind, 305,000-square-foot recycling and packaging facility in Vernon, Los Angeles County, positioning the family-owned beverage manufacturer as one of the few US companies operating a complete bottle-to-bottle recycling process. The facility, previously operated by rPlanet Earth before shuttering in September 2025, was purchased from rPlanet Earth Los Angeles Holdings and rPlanet Earth Los Angeles. Along with the acquisition, Niagara obtained the rPlanet Earth brand, signaling its commitment to advancing circular economy solutions in the beverage industry. Investing in equipment: "We're proud to bring this facility back to life and become one of the few companies in the country with a true bottle-to-bottle process," said Rali Sanderson, president of Niagara Bottling. "As part of this work, we're investing in new equipment so we can turn rec...

Its main strengths are fast drying, smooth transparent films, and good compatibility with solvents and plasticizers. By adjusting nitrogen content and viscosity, formulators can balance drying speed, hardness, and flexibility. #coatings #paintformulation #materials In NC lacquers, nitrocellulose enables quick surface drying, easy handling, and good polishability. It is widely used in wood coatings, musical instruments, and decorative finishes where appearance and application efficiency are key. #chemicalengineering #surfactants Compared to other resins like polyurethane or acrylics, nitrocellulose dries physically rather than chemically. Its advantages include simple formulation, excellent surface finish, and repairability. Limitations are lower chemical and heat r...

In semiconductor and aerospace applications, the material usually has to deal with more than heat alone. Dimensional stability, wear, friction, contamination control, and static management can all shape whether a part holds up in use. 𝗪𝗵𝘆 𝗖𝗵𝗼𝗼𝘀𝗲𝘀 𝗗𝘂𝗿𝗮𝘁𝗿𝗼𝗻® 𝗣𝗔𝗜 ? Duratron® PAI is built for those conditions. 𝗜𝗻 𝘀𝗲𝗺𝗶𝗰𝗼𝗻𝗱𝘂𝗰𝘁𝗼𝗿 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀: grades including Semitron® MPR1000, Semitron® ESd 520HR, and Duratron® T4203, T5030, and T5530 are used in vacuum chambers, test fixtures, and precision parts. 𝗜𝗻 𝗮𝗲𝗿𝗼𝘀𝗽𝗮𝗰𝗲: Duratron® T4301 PAI AE is used for bearings, seals, and structural components where wear resistance, low friction, and lower weight matter. For manufacturers looking to improve part reliability in demanding semiconductor and aerospace environments, Duratron® PAI is worth exploring.

Today's KNOWLEDGE Share 100% purity in PCR polyolefins? In reality, rPP often means PP + a bit of HDPE. In post consumer recycled (PCR) streams, achieving truly single polymer purity for rPP or rHDPE is harder than many specs assume. Why? 1) PP and HDPE behave almost the same in classic swim sink separation Both PP (~0.91 g/cm³) and HDPE (~0.95 g/cm³) swim in water based sink–sink systems, so you can’t “density separate” them from each other in that step. Even if a plant has 10+ sorting stages, this specific pairing remains a bottleneck. Just NIR and AI manage the separation. 2) Fillers change the game (and can “fake” separation) If PP or PE is filled with inorganic additives, the density increases and parts may sink. Reality from the line: In many commercial rPP / rHDPE grades, a small cross contamination is normal. In practice, pure rPP often still contains around 1% PE/HDPE. And that small amount normally doesn’t cause problems in further processing. 🔬 Measuring that contam...

Both industries operate in highly regulated, safety-critical environments and carry responsibility for human life. Yet one industry reinvented itself through bold adaptation — while the other progressed far more cautiously. In aviation, aircraft evolved from mechanical systems to digital fly-by-wire, from riveted aluminum to composites, from four engines to two. One of the most telling shifts is how aviation adopted additive manufacturing (AM). Aviation did not treat AM as an experiment or a premium niche. It treated it as a strategic manufacturing capability. Today, AM is used for flight-critical engine components, structural brackets, heat exchangers, and geometries...
