Revêtements poudre:Peinture poudreIndex. décimale : 667.9 Revêtements et enduits Résumé : A new method for the synthesis of sustainable and cost-efficient polyester resins for powder coating has been developed by combining the chemical recycling of polymers recovered from post-consumer waste streams with the use of bio-based monomers as building blocks for the polymerisation. Some of these monomers are very specific and brought to the development of materials with unique properties, which cannot be obtained from traditional petrochemicals. Therefore, the casting produced using this new approach presents applicative properties similar to and, in some cases, superior properties, compared with commercial coatings obtained from non-renewable resources. This aspect combined with the sustainable character of the new technology gives important advantages in comparison with conventional resins and opens new possibilities In market segments where the current powder coating has limited applications due to some intrinsic limitations.

SABIC has entended its offering of custom engineered thermoplastic compounds to sustainable PBT grades with mass balance-certified glass fibre content from post-industrial sources. The new LNP ELCRIN iQ compounds are in keeping with the company's drive towards net zero carbon emissions and circularity. At the same time, they provide drop-in solutions with no compromises in mechanical or thermal properties, impact strength or colourability vs. comparable glass fibre-reinforced virgin materials.

Produits et matériaux recyclésIndex. décimale : 668.4 Plastiques, vinyles Résumé : The mass of recyclable plastic waste has been growing steadily for years. This is mainly the result of technical advances made in both processing and sorting. At the same time, the recycling targets set by the EU are piling more and more pressure on companies to increase the amount of recycled plastics in their products. This in turn is raising the requirements imposed on the recycled materials themselves. Aside from the nature of the polymer and the previous application, the color of the recycled material is important. Note de contenu : - Monitoring the color profile of the recycled materials

Structure moléculaireIndex. décimale : 668.4 Plastiques, vinyles Résumé : A study was carried out to evaluate the effects of molecular weight and molecular structure on non-isothermal crystallization behavior of recycled and virgin polyamides (PA) and their corresponding glass fiber (GF) composites. Two different recycled polyamides (PA), namely post-industrial waste (PIW) and post-consumer waste (PCW) were used. The former was obtained from a fiber manufacturer and the latter was recycled from used carpets. The molecular weights of the resins were measured by intrinsic viscosity (IV) measurements and 13carbon nuclear magnetic resonance (13C-NMR). The NMR technique also provided information on PA structure, cis and trans amide conformers content and residual unreacted monomer. Non-isothermal crystallization of the resins was studied using differential scanning calorimetry (DSC). The molecular weights of recycled materials were higher than that of virgin injection molding grade PA-6. However, the crystallization rates (indicated by t1/2) of recycled resins were faster. It could be attributed to the presence of TiO2 in recycled materials. Moreover, the higher cis-amide conformer content of recycled resins suggested higher segmental mobility. On the other hand, the crystallization rate of composites based on recycled PA-6 was slower than that of composites based on the virgin PA-6. The suppression of crystallization rate was apparently due to PA-66 added during the preparation of reinforced recycled resins. This behavior was confirmed by model compounds based on PA-6/PA-66 blends. Note de contenu : - EXPERIMENTAL : Materials - Sample preparation and characterization

Based on a sustainable upcycling process of a unique locally sourced mandarin from the Greek island of Chios, MelanoGrayâ„¢ is an anti-hair greying essence that stimulates melanin synthesis and protects melanocytes from stress-induced malfunction. This unique active ingredient was shown to markedly reduce the quantity of grey hair in both men and women, even during times of psychoemotional stress when hair greying can be accelerated.Note de contenu : - Hair greying
