According to Markets and Markets, the pressure sensitive adhesives (PSAs) are projected to reach $15.76 billion by 2026. With growth in large part due to increasing end-use in packaging and transportation markets, PSAs come in several different forms and offer distinct characteristics.
Gain insight into these forms and their characteristics to understand which works best for your application needs.
Types of solvent-based PSAs are acrylic, styrene block copolymer, silicone and polyisobutylene. Applied to a web or substrate, they offer excellent moisture resistance.
Water-borne PSAs are comprised of acrylic, vinyl acetate ethylene and certain elastomer types. Typically lower cost than solvent-based, these PSAs are environmentally friendly. However, they offer relative poor moisture resistance.
- Hot Melt
Types of hot melt PSAs include polyurethane, acrylic, styrene block copolymer and polyisobutylene. Formulated with tackifying resins, oils and antioxidants, they can be extruded at temperatures to 150°F.
