Langues : Américain (ame) Catégories : Adhésifs à usages médicaux Adhésifs sensibles à la pression hydrocolloïdes Transmission de vapeur d'humidité Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Medical adhesives are found all around us, from the hospital to the nursing home and even your own home, you will see them at work. Envision any device that sticks to the skin and it is probably doing so by means of a medical grade adhesive. Traditional applications include bandages, dressings, electrodes, grounding pads and ostomy appliances. At your local drugstore, you will find finger bandages, pore cleaning strips and nicotine patches sold over the counter. In 1874, Robert Wood Johnson and George Seabum began large scale manufacturing of surgical tapes in East Orange, N.J. The adhesive was made from natural latex rubber and it did a fairly good job of securing various devices to the body during surgery. Johnson and his two brothers later went on to start a company, Johnson and Johnson. It was not until the advent of acrylic-based polymers in the 1950s that modifications could be made to peel, tack and shear properties based on the specific needs of the patient. For example, an adhesive could be formulated with very aggressive adhesion for use on a cardiac lead used during a treadmill stress test while a much gentler one could be used on the fragile skin of an infant or elderly person. Today, the trend is for adhesives to do more than just adhere well. They are expected to perform other functions such as: -conduct electricity either into or out of the body; -deliver active ingredients to the skin such as moisturizers, salicylic acid and vitamins; -replace sutures ans staples by closing breached skin and internal tissue; -deliver drugs through the skin and into the blood stream; -provide a molecular pathway for evaporation of moisture trapped against the skin; -and promote healing by creating optimum healing environments, absorbing moisture, and controlling infection. In the future, look for the commercialization of de-activatable adhesives and "smart" adhesives which can indicate when a dressing needs to be removed due to the presence of infection, time duration or other environmental triggers.

"Hot" urethanes / Renée Van Schijndel in ADHESIVES AGE, Vol. 44, N° 12 (12/2001)  

[article]  inADHESIVES AGE > Vol. 44, N° 12 (12/2001) . - p. 27-31 et p. 46 Titre : "Hot" urethanes : The influence of using dimerized fatty acid technology for polyurethane hot-melt adhesives Type de document : texte imprimé Auteurs : Renée Van Schijndel, Auteur ; Eric Appelman, Auteur Année de publication : 2001 Article en page(s) : p. 27-31 et p. 46 Langues : Américain (ame) Catégories : Acides gras Adhésifs thermofusibles Dimères Polyesters Polyols Polyuréthanes Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Dimerized fatty acids have long been used in polyamide hot-melt adhesives. It can be expected that some of the benefits they add to these adhesives, like flexibility and hydrophobicity, can be transferred to other adhesive resins. Polyurethanes, where the dimerized acid is easily introduced via a polyester polyol, is an obvious candidate. Uniqema has developed a range of derivatives of dimerized fatty acids under the product name of Priplast. These dimerized acid-based polyester polyols were studied as building blocks for reactive hot-melt adhesives. Initially, the influence of dimerized fatty acid-based polyester polyols on the properties of polyurethane elastomers was tested. Subsequently, the properties of reactive polyurethane hot-melt adhesives were studied after full cure (final adhesive properties). Thirdly, a study was performed on the initial bond of the adhesives (green strength) and ways to improve the green strength. The results of the study are presented here.

Beat the heat / N. Julian K. Danvers in ADHESIVES AGE, Vol. 44, N° 12 (12/2001)  

[article]  inADHESIVES AGE > Vol. 44, N° 12 (12/2001) . - p. 32-37 et p. 48 Titre : Beat the heat : New challenges for curing material on heat-sensitive substrates Type de document : texte imprimé Auteurs : N. Julian K. Danvers, Auteur Année de publication : 2001 Article en page(s) : p. 32-37 et p. 48 Langues : Américain (ame) Catégories : Adhésifs -- Séchage sous rayonnement ultraviolet Adhésifs thermofusibles Electrodes Micro-ondes Réflectivité thermique Systèmes de refroidissement Index. décimale : 668.3 Adhésifs et produits semblables Résumé : With the advances being made in material science and technology, there is an increase in the amount of polymeric materials used within today's manufacturing environment. The growth of UV curing for its process, performance and environmental factors is presenting new challenges on how to best cure material on thermally sensitive substrates. This article will look at the technology and processes that can be used when the inherent heat generated as part of the UV-source is detrimental to the substrate. It will investigate different types of UV curing systems that can be used for paying special attention to the heat transmission properties associated with them as well as looking at some sample applications in which they can be used. For the benefit of this article, discussions will be based around electrode (arc) and microwave UV equipment. While EB (electron beam) and pulsed UV are both alternative radiation-curing technologies, these will be not covered.

Warming up to polyamides / Ronald L. Gordon in ADHESIVES AGE, Vol. 44, N° 12 (12/2001)  

[article]  inADHESIVES AGE > Vol. 44, N° 12 (12/2001) . - p. 39-43 Titre : Warming up to polyamides : Hot-melt polyamides perform well in applications requiring good heat resistance Type de document : texte imprimé Auteurs : Ronald L. Gordon, Auteur Année de publication : 2001 Article en page(s) : p. 39-43 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Adhésifs thermofusibles Automobiles -- Habitacles Polyamides Un 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. Résistance thermique Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Hot-melt polyamides perform extremely well in applications where elevated temperature resistance is required. However the real success of providing heat resistance alone, but in being able to provide the other necessary properties such as hot tack, adhesion, strength, flexibility and impact resistance at low temperatures, in addition to the required heat resistance. For extremely demanding applications, curable polyamides can provide all of the application properties that are characteristic of the standard hot-melt polyamides, while providing heat resistance, chemical resistance, strength and flexibility beyond the range where any of the non-curing hot melts perform.
