| Résumé : |
Understanding the variables involved in PSAs can lead to first-time-right decisions on adhesive selection and processing.
Depending on the desired performance properties and targeted end-use application, a variety of PSAs are available for foam tape applications. With regards to the adhesive, polymer and formulation choices can be targeted to meet the needs for the specific foam type. In addition to adhesive modifications, changes to the foam itself and/or the coating process can also be implemented to improve the adhesive’s anchorage to the foam substrate. Understanding these variables can lead to first-time-right decisions on adhesive selection and processing in order to meet the needs for any foam tape application. |

- Monomers and molecular weight of acrylic-based PSAs
- Softening point in hot-melt PSAs
- Tackifiers in PSAs
- FIGURES : 1. Foam tapes can be either single- or double-coated constructions - 2. Adhesive anchorage to foam is generally improved by increasing th eadhesive coat weight - 3. General rheology model for storage modulus vs. temperature of an acrylic PSA - 4. Lower softening point holt mel adhesives show better anchorage on various foam types - 5. There is an optimum amount that can be added before loss of peel, tack, and shear performance
