[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 21, N° 7 (07/2014) Titre : Adhesive promotes unbreakable displays in automotive applications Type de document : texte imprimé Année de publication : 2014 Langues : Américain (ame) Catégories : Adhésifs dans les automobiles Adhésifs dans les équipements électriques/électroniques Index. décimale : 668.3 Adhésifs et produits semblables Résumé : A new high-tech adhesive prevents glass splinters in vehicle crashes. SCHOTT and DELO® Industrial Adhesives have collaborated to develop an unbreakable glass cover composite for vehicle navigation and entertainment screens, in which a high-tech adhesive bonds the display to the special glass cover. In a series of tests, both companies demonstrated that their new displays satisfy all safety requirements imposed by the automotive industry and protect occupants of vehicles against cutting injuries. The two companies tested how completely bonded displays behave in a crash compared to conventional displays with an air gap between the glass cover and LCD. For this purpose, they conducted head-on crash tests according to the criteria of the international ECE R21 standard in which a steel ball with a weight of 14.99 lb (6.8 kg) impacts on the displays with a speed of approximately 15 mph (24.1 km/h). In the tests, the standard displays were completely destroyed by the steel ball, and hundreds of glass splinters were blown off in all directions by the impact. In contrast, only the inner liquid crystal display of the completely bonded displays with the special SCHOTT glass broke. The glass covers remain completely intact, which protects the passengers against cutting injuries.

Soft silicone adhesives crucial for a traumatic advanced wound care dressings / Derek Rudnak in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 21, N° 7 (07/2014)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 21, N° 7 (07/2014) Titre : Soft silicone adhesives crucial for a traumatic advanced wound care dressings Type de document : texte imprimé Auteurs : Derek Rudnak, Auteur Année de publication : 2014 Langues : Américain (ame) Catégories : Adhésifs à usages médicaux Colles:Adhésifs Dents -- Soins et hygiène Pansements Silicones Les 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 : Mention the words “silicone” and “medical” in the same sentence, and it’s arguable that most people will immediately think of silicone’s well-known (and occasionally maligned) usage in artificial breast implants. However, silicone has other significant and successful applications in medical products. Silicone is particularly successful as an adhesive for advanced wound care dressings, which has been one of the most challenging riddles in dressing manufacturing and usage for nearly half a century. In recent years, silicone dressings have blossomed into a segment that garners $130 million annually; these figures are projected to increase.

Developing pressure-sensitive adhesives for low-temperature applications / Alejandro C. Esquivel de la Garza in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 21, N° 7 (07/2014)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 21, N° 7 (07/2014) Titre : Developing pressure-sensitive adhesives for low-temperature applications Type de document : texte imprimé Auteurs : Alejandro C. Esquivel de la Garza, Auteur Année de publication : 2014 Langues : Américain (ame) Catégories : Adhésifs -- Emballages Adhésifs sensibles à la pression Copolymère styrène butadiène styrène Copolymère styrène isoprène styrène Etiquettes Rubans adhésifs Transition vitreuse Index. décimale : 668.3 Adhésifs et produits semblables Résumé : FINAT defines low-temperature adhesion as the ability of pressure-sensitive coated material to adhere at temperatures below 5°C. Today, many applications require adhesion that must be maintained at temperatures of -25°C or lower. One of the main characteristics of pressure-sensitive adhesives (PSAs) is their viscoelastic character, which allows optimal mobility for wetting substrate surfaces in order to bond and obtain maximal adhesion, while absorbing energy as viscoelastic deformation to maintain an effective bonding. Viscoelastic character of an adhesive is given by the elastomeric polymer present in its formulation. PSAs used in applications like tapes and labels for frozen food packaging and other applications in cold environments require special attention for the ingredients selection and, more specifically, in the polymer selection. At temperatures below the glass-transition temperature (Tg), a polymer has a brittle consistency and loses its deformation capacity. Consequently, an adhesive made with that polymer loses its mobility and elastomeric capacity to maintain the adhesion. It is therefore important to select a polymer that will adequately maintain its elastomeric characteristics at reduced temperatures; this is a low-Tg polymer.
