EMAA Material Properties and Applications
Ionomer (Polythylene Methacrylic Acid), or EMAA, an ion-containing polymer, is a versatile engineering resin known for its viscosity, good electrical conductivity and durability. Ionomers are transparent polymers, crosslinking their molecules “ionically”. The ionic bonds can be separated when heated, allowing them to be processed, and when cooled the ionic bonds return. The ionic crosslinking makes the material very tough and cut resistant. Ionomers can also be blended with resins to increase the cohesive strength without diminishing the overall tackiness of the resin, making them ideal for applications such as water-or solvent-based adhesives.
