HPMC, or Hydroxypropyl Methylcellulose, is a widely used polymer with the following key characteristics: Water Solubility: HPMC dissolves in cold water to form a clear or slightly cloudy viscous solution. Thermal Gelation: HPMC exhibits thermal gelation, meaning it forms a gel when heated to a specific temperature and reverts to a solution when cooled. Thickening Agent: It is an excellent thickener, providing viscosity and improving the texture in various applications. Film-Forming Ability: HPMC can form strong, flexible, and transparent films, making it useful in coatings and films. pH Stability: It remains stable over a broad pH range (approximately 3 to 11), ensuring functionality in diverse environments. Non-Ionic Nature: Being non-ionic, it is compatible with ionic and non-ionic compounds and does not react with metal ions. Biodegradability: It is biodegradable and safe for use in food, pharmaceuticals, and personal care products. Adhesion: HPMC provides good adhesion properties, particularly in construction applications like tile adhesives and plasters. Moisture Retention: It retains water effectively, which is especially beneficial in construction materials and cosmetics. Chemical Stability: It is stable against oxidation, light, and most common chemicals. These characteristics make HPMC highly versatile, used in industries such as construction, pharmaceuticals, food, personal care, and more.

https://lnkd.in/gptcb4Bh Polyurethane, a material with monomers linked by carbamate groups, is widely used in flexible and rigid foams, coatings, adhesives. In addition to existing recycling methods like glycolysis and mechanical recycling, the authors introduced hydrogenolysis under a hydrogen atmosphere using an Ir catalyst with a phosphine-benzimidazole bidentate ligand. This method produces formamide and alcohol from carbamate. Remarkably, the catalyst selectively breaks down the carbamate bonds while leaving other functional groups such as esters and formamide, which are generally more susceptible to harsh reduction conditions, intact. The broad substrate scope of this method is particularly significant for polyurethane recycling, as polyurethanes often contain a diverse array of monomer materials tailored to specific applications.

https://lnkd.in/gz4cn7Zg Abstract. As an alternative to polybrominated diphenyl ethers (PBDEs), decabromodiphenyl ethane (DBDPE) has become one of the most important new brominated flame retardants (NBFRs). However, little is known about whether this emerging contaminant may has an environmental fate similar to PBDEs. It finds application as an additive flame retardant in the manufacture of plastics, such as high-impact polysterene (HIPS), acrylonitrile butadiene styrene (ABS), polypropylene, in rubber products, adhesives and sealants, in different applications related to manufacture of textiles, such as cotton, polyester, vinyl ... DBDPE plays a significant role in the global flame retardant industry, driving innovation and economic growth. As regulatory challenges arise, a collaborative and measured approach is necessary for scientific and evidence-based decision-making. By navigating these challenges with pragmatism and cooperation, countries like China can continue to effectively protect their citizens from the danger of fire, while at the same time preserving their socio-economic stability. https://lnkd.in/gfQ4Nfp2 sales@oceanchem-group.com WhatsApp 00861865368787 Jackson Han

I am excited to share with you our new article describing a method for olefins determination in plastic oils using GCxGC-FID without the need for an MS detector. https://lnkd.in/eF9HxXAv Distinguishing olefins from naphthenes using EI-MS is challenging due to very similar MS spectra of those structures. Processing of MS spectra is time-consuming and can often result in wrong identification. Moreover, as we demonstrated in the article, even in GCxGC, the coelution of olefins with saturated compounds can hardly be eliminated, affecting the correctness of olefins determination. Our method can be applied for olefins determination in various oils originating not only from pyrolysis and HTL of plastics and was extensively validated. It has the premise of simplifying this analysis and helping you reach more accurate results while saving time when processing the GCxGC results. It doesn't require an MS detector and a highly experienced operator to be able to process MS spectra reliably, so it is a perfect solution for R&D. The article is published with open access. If you have any questions or struggle with implementing the method, do not hesitate to contact us.
