  A groundbreaking study has been published in the esteemed journal, Cell Reports Physical Science, showcasing a novel method for the recycling of unsaturated polymers such as rubber and plastics. The paper introduces a process using oxygen and light to help break down the polymers naturally. It is authored by Dr. Junpeng Wang, assistant professor of polymer science at The University of Akron, and a team of current and former students including Dr. Hanlin Chen ‘23, Dr. Devavrat Sathe ’23, Xin Guan and Puyang Zhang, Introducing Unsaturation to Enhance Reactivity of Polymers: Since the 1950s, the mass production of plastics has resulted in the creation of approximately 8.3 billion metric tons of polymers. Unfortunately, the majority of these polymers have been discarded or incinerated, leading to significant environmental contamination. Only 600 million metric tons have been effectively recycled. The stability and durability of commercial polymers, particularly polyolefins, which con...

Today's KNOWLEDGE Share Warpage of a GF filled nylon part is extremely dependent on temperature and moisture uptake. Temperature increase is responsible for matrix expansion (negligible for the fibers though), and moisture uptake produces matrix swell (again GF does not care much). So if a part is warped when dry as molded at room temperature (that is what simulation codes will predict for you !!) it will tend to "UNWARP" as you heat the part or let it uptake moisture. This effect can perfectly be simulated, if you account properly for the anisotropic elastic properties and fiber orientation and know the swell rate with water uptake. For temperature induced UNWARP you will need detailed CTE (T) in x, y and z though to get it right ! Those CTE's, with the needed level of detail, are not available directly from Flow Analysis codes for the moment, but e-Xstream engineering, part of Hexagon’s Manufacturing Intelligence division Digimat software can provide those. source:V...

Today's KNOWLEDGE Share CYANATE ESTER: Cyanate ester resins are a special class of polymeric materials whose molecules contain structural units of cyana(-CN) and  carbonyl groups(-C00). Cyanate esters exhibit attractive physical, electrical, thermal, and processing properties. Blends with epoxy and bismaleimide are common. Cyanate esters bear basically two cyanate groups (-OCN) attached to an aromatic ring. Also, aryl cyanate esters with additional allyl groups are known, e.g., 1-allyl-2-cyanatobenzene. Cyanates are formed by the reaction of phenols with cyanogen halides. Cyanate ester resins are superior to epoxy resins, phenolic resins, and bismaleimide resins. They combine the advantages of epoxies, the fire resistance of phenolics, and the high-temperature performance of polyimides. Dicyanates of bisphenol derivatives are currently used in composites with established reinforcements such as carbon fiber, glass fiber, silica cloth, pitch-based graphite fibers. Properties of Cyan...

Suzuki Motor Corporation and Banas Dairy will invest over Rs 250 crore to establish four biogas plants in Gujarat. The project is aimed at making fuel for automobiles by refining methane from biogas. The biogas is created by fermenting cow dung, and the resulting liquid fertilizer will be used in agriculture, according to Banas Dairy Chairman Shankar Chaudhary, reported Ahmedabad Mirror. An agreement between Maruti Suzuki and Banas Dairy will be inked for the same.The four biogas plants, set to begin operations in 2025 in Banaskantha district, will have a combined biogas production capacity of 500,000 liters. Each plant will also feature a biogas-filling station. Suzuki’s commitment to achieving carbon neutrality through proactive biogas production initiatives will be highlighted during the visit of Suzuki President Toshihiro Suzuki to Banaskantha. He will tour the biogas plant, the cheese plant at Palanpur dairy, and the potato processing plant in Sanadar. In December 2022, Suzuki sig...

Liqcreate, a manufacturer of 3D printing materials, has introduced a new technical 3D printing resin called Liqcreate Rigid Pro. This resin offers high chemical resistance, good temperature resistance and high strength and rigidity. These properties make it ideal for a wide range of applications in the engineering, automotive, electronics and oil and gas industries. Liqcreate Rigid Pro is a rigid photopolymer resin that can be processed on most resin-based 3D printers. It is compatible with Digital Light Processing (DLP), Liquid Crystal Display (LCD) and laser-based 3D printing systems in the 385-420 nm range. This broad compatibility ranges from entry-level systems from Anycubic, Elegoo and Creality to professional systems such as Asiga, Nexa3D and UnionTech Martrix. A key advantage of the Rigid Pro resin is its chemical resistance. Parts made with this resin can withstand a wide range of chemicals such as mild acids and bases. In addition, the material is also resistant to petrol and...

Henkel Adhesives Technologies India Private Limited (Henkel India) announced the completion of Phase III of its manufacturing facility in Kurkumbh, near Pune, Maharashtra.

Today's KNOWLEDGE Share New Thermoresponsive Adhesive for Pain-free Wound Dressings: In a project funded by the Baden-Wuerttemberg Foundation, researchers at the University of Freiburg have developed an innovative adhesive polymer for wound dressings that adheres securely under temperature control but is easy to remove. This approach enables dressings to adhere firmly to the skin or wound site at body temperature without restricting the patient's freedom of movement. However, when the dressing is cooled, such as with a cold pack, it can be removed very easily and without pain. Additionally, no adhesive residue remains on the healing tissue. The adhesive material's property of "switchable stickiness" is achieved through a crystallization process. Adhesive Made of Copolymers and PVA Fatty Acid Esters: The research team at the Institute of Macromolecular Chemistry at the University of Freiburg, led by prof. Dr. Rolf Mülhaupt and prof. Dr. Thorsten Steinberg, who supe...
