SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).Index. décimale : 668.3 Adhésifs et produits semblables Résumé : The global manufacturing industry has faced many challenges and has had to adapt to growing megatrends across the globe to remain competitive. Manufacturers have had to become more customer focused and flexible to keep up with consumers who are better informed about products on the market and expect new and improved products on demand. In addition, factory floors have also had to adapt to digitization by incorporating latest-technology systems and equipment, with an increasing uptake of robotics to complement factory workers on the assembly line. Adapting to these megatrends while optimizing production, logistics and distribution efficiencies is essential to ensuring that companies remain competitive.
As these changes are driving advances in manufacturing processes and technologies, they are also driving material improvements to ensure that final products are reliable and of high quality. Silicone foams for compression gaskets address customer needs for greater flexibility, production efficiencies and the increasing use of robotics on the assembly line (see Figure 1). Reformulated to meet current REACH standards, the foams are a hybrid technology, falling under room temperature vulcanization (RTV) solutions but using an addition cure mechanism that is typical for high-temperature vulcanization (HTV) products. The silicone foams are designed to be dispensed and cured directly on parts to form an integrated compression gasket.En ligne : http://www.adhesivesmag.com/articles/95156-enhancing-assembly-line-efficiencies- [...] Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28762

PolyuréthanesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Hydroxyl-terminated polybutadiene (HTPB) resins occupy a unique space within the landscape of commercially available polyols in the context of polyurethane elastomers. Characterized by low temperature flexibility, hydrophobicity and hydrolytic stability, polyurethane elastomers present solutions to strenuous applications in the adhesives and sealants market. Due to the hydrocarbon nature of the polymer backbone, these elastomers also have extremely low dielectric constant, dissipation factor, and moisture vapor transmission rate (MVTR) properties.
With the fast growth of the information industry, electronic products such as mobile phones, personal digital assistants and notebooks have become daily necessities for many of us. Multifunctional urethane (meth)acrylates derived from hydrogenated HTPB resins, which have excellent properties against oxidation and a relatively high refractive index of about 1.5, have gradually established their use as essential ingredients in UV-cured compositions in a clear optical index-matched adhesive for the bonding of two or more optical components together.Note de contenu : - Encapsulants
