Novel, all-acrylic pressure-sensitive adhesive compositions with inherently lower surface energy display significantly improved adhesion to LSE substrates such as polyethylene and polypropylene.
The prevailing trend toward the use of lighter weight and lower cost engineered plastics in automotive, construction, aerospace, electronics, and other industrial uses has created a need for pressure-sensitive materials that can bond well to these new, inherently low-surface-energy (LSE) plastics. This article discusses novel, all-acrylic compositions with inherently lower surface energy that display significantly improved adhesion to LSE substrates such as polyethylene and polypropylene.

This article examines the external events that have led to greater awareness of adhesives’ performance in the event of a fire, the standards and regulations that are being imposed, and the development of new fire-resistant materials.
Historically, fire resistance has not generally been a significant requirement when specifying adhesive systems. Recent incidents, however, indicate that this may soon change. These include events outside of the formulators’ arena, such as increased sensitivity to the performance of components in a fire, and events within the formulators’ arena, such as the development of flame-resistant additives.
