Carton closure hot-melt packaging adhesives using ethylene vinyl acetate (EVA) polymer systems have been used for decades due to their availability, formulation latitude and performance attributes. Packaging adhesive formulations typically contain polymer, tackifier resin and wax.
Over the last 50 years, the aerospace and aircraft industries have used silicone in an ever-growing number of applications. Silicone inherently has high dielectric strength (typically ≥ 500 V/mil) and a large coefficient of thermal expansion (CTE), allowing it to absorb stresses during thermal cycling.

Tiny implants to monitor bodily functions or to provide insulin or other drugs based on immediate need would be an advancement in personalized medicine. But a problem inherent in implants is the tendency of the human immune system to recognize the device as an invader and encapsulate it, preventing the device from doing its job.
For technical applications that require some form of adhesion, pressure-sensitive adhesives (PSAs) usually offer the best value, given their affordability, ease of use and clean application, when compared to alternative bonding options like mechanical fasteners or liquid adhesives.
On October 21-23, the Adhesive and Sealant Council will hold its biannual convention in Minneapolis.

Industry professionals will be exposed to new trends, technologies and topical expertise at the Adhesive and Sealant Council’s (ASC) Fall Convention & Expo, which will take place next month at the Hilton Minneapolis in Minneapolis.
Most manufacturers are currently or have been involved in some form of lean process. Your company may be well down the path or just starting out, or your customers or suppliers may be going lean. The Lean Enterprise Institute characterizes lean as “creating more value for customers with fewer resources.”
