For example, many types of pressed wood contain formaldehyde, a known carcinogen that releases chemical fumes into the air for many years. In addition, in the 1970s, it was common for homeowners to install urea-formaldehyde foam insulation (UFFI) to save energy. A substantial number of these homes had high levels of formaldehyde in the indoor air soon after installation, according to the U.S. Consumer Product Safety Commission. Statistics show that “off-gassed” VOCs can result in a plethora of both short- and long-term adverse health effects, while also posing a number of environmental concerns—from indoor air quality to ground-level ozone formation. According to the Minnesota Department of Health, the toxicity and health risk of VOCs depends on each specific chemical, how much out-gassed chemical is in the air, and how long and how often a person breathes it in. Obviously, VOCs should be avoided. Today, many converters and manufacturers pay close attention to the materials used in their end products in order to help ensure that the products are safer and healthier for consumers; these include pressure-sensitive adhesives (PSAs).

Pressure-sensitive adhesives are in the driver's seat / Janet Page in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 23, N° 7 (07/2016)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 23, N° 7 (07/2016) Titre : Pressure-sensitive adhesives are in the driver's seat : Industrial PSA tapes with high temperature resistance bring new value to production assembly in automotive and transportation markets Type de document : texte imprimé Auteurs : Janet Page, Auteur Année de publication : 2016 Langues : Américain (ame) Catégories : Adhésifs -- Propriétés mécaniques Adhésifs dans les automobiles Adhésifs sensibles à la pression Assemblages collés Essais d'adhésion Résistance thermique Rubans adhésifs Sièges Index. décimale : 668.3 Adhésifs et produits semblables Résumé : For years, pressure-sensitive adhesives (PSAs) have been creating new opportunities for improved production processes in the automotive and transportation markets. According to the Adhesive and Sealant Council Inc., one of the first uses of acrylic PSA tapes in the automotive market came about in the 1960s as a solution for replacing mechanical fasteners to attach vehicle trim, thus improving corrosion resistance. In the decade that followed, the association notes that acrylic adhesives were being used instead of mechanical fasteners in wire tacking, allowing for fewer parts needed for assembly; in the 1980s, hot-melt adhesives were replacing screws in interior automotive plastic bonding applications and UV-curable adhesives took the place of fasteners in headlamp assembly. Innovations like these continued throughout the 1990s and 2000s. Today, PSAs are found from bumper to bumper in automotive assembly eliminating holes that can allow moisture or liquids to enter a vehicle ; as sources for noise dampening and vibration reduction ; and adhering weather-stripping materials or interior vehicle components like dashboards, glass, mirrors, fabric, carpet, and more. Note de contenu : - Benefits of PSAs in transportation applications - New technology brings opportunities - Proper selection : Substrate considerations - Environmental exposure - Required adhesion level - The future of PSAs - FIGURES : 1. From adhering interior trim to fabricated rubber gaskets and seals, pressure-sensitive adhesive are used in numerous places throughout RV, marine, and automotive applications - 2. To test required PSA, adhesion level, three common test methods are used : peel adhesion, quick tack and shear adhesion/cohesion - 3. A PSA's composition consists of four key parts : adhesive, carrier, release coating, and liner - 4. Design to withstand extremely high-temperature applications, such has automotive under-the-hood applications, high-temperature acrylic PSA's bring added value to production assembly in the automative and transportation market En ligne : http://www.adhesivesmag.com/articles/94732-pressure-sensitive-adhesives-are-in-t [...] Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28782 [article]
