Priplast technology can be used to create high-performance adhesives—either moisture curing, hot melt or PUD. Priplast dimer-based polyester polyols modify adhesives to become hydrophobic, enhance low-temperature flexibility or impact strength, and provide thermo-oxidative and thermal stability combined with excellent hydrolytic stability. These properties are combined with the enhanced environmental profile of a renewable modifier, with up to 100% renewable carbon content.En ligne : http://www.adhesivesmag.com/articles/92864-advancing-adhesives-bio-based-polyols [...] Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=23361

DiamineUne diamine est un type de polyamine contenant exactement deux groupes amine. Les diamines sont principalement utilisées comme monomères pour synthétiser des polyamides, des polyimides et des polyurées. La principale diamine produite est le 1,6-diaminohexane, précurseur du Nylon 6-6, suivie de l'éthylènediamine1. L'hydrazine (H2NNH2) n'est en général pas considérée comme une diamine puisque ce n'est ni une amine (pas de carbone), ni une dibase.

Terpolymère acrylonitrile butadiène styrèneIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Dimerized fatty acids have been used for many years in polyamides, polyesters, epoxy resins and amine curatives. They are obtained through the conversion of unsaturated fatty acids (from natural oil and fat) by a combination of pressure, temperature and catalysis, followed by purification processes.
Starting from the C18 fatty acids that nature typically provides, the dimer acid is a molecule with 36 carbon atoms, which makes it the longest dioic acid available. The benefits that the hydrocarbon character and non-crystallinity of these C36 diacids add to coatings and adhesives are mainly related to the low glass-transition temperature (Tg) and their hydrophobic nature. These properties induce flexibility, hydrolytic resistance, thermo-oxidative resistance, moisture repellency and adhesion to a wide range of substrates.
For several years, dimer fatty diols and a range of polyester polyol derivatives of dimerized fatty acids have been available for use in various polyurethane applications to enhance durability, flexibility, and hydrophobicity.* New bio-based, amine-functional building blocks have been developed that extend the range of acid- and hydroxyl-functional fatty dimers and derived polyesters (see Figure 1).** This new technology provides benefits in many applications.Note de contenu : - FIGURES : 1.

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

The reaction parameters involved in the synthesis of WBE from ESO have been optimized based on physicochemical properties like hydroxyl value, epoxy equivalent value and degree of solubility of WBE. The WBE obtained after 5 and 6 h of reaction time was found to be of optimum composition with balanced physicochemical properties. The mechanical, thermal and physicochemical properties of WBE obtained after 6 h of reaction time revealed relatively better performance characteristics as compared to ESO.
