  • What are Tackifiers & plasticizers in PSAs?
  • Source: Extance, A., “Using Tackifiers and Plasticizers in PSAs”, SpecialChem, February 9, 2009. Plasticizers are organic liquids or solids that are incorporated by melt processing or diffusion into a compatible polymer to reduce interaction between molecules and improve molecular mobility.
  • What is a hydrocarbon resin tackifier?
  • Hydrocarbon resins tackifiers are either aliphatic, aromatic, or mixtures of the two. Hydrocarbon resin tackifiers are polymerized to raise their softening points to a level that is useful in adhesives. They are low molecular weight amorphous synthetic polymers. Table below summarizes the most common types of hydrocarbon resin tackifiers.
  • Why are Tackifiers important?
  • Tackifiers are important constituents in adhesives formulations in order to maintain the correct balance between adhesion and cohesion. They must be considered with regard to the end-used properties, adhesive processing as well as compatibility with base polymer to achieve desired performance requirements.
  • What are Tackifiers made of?
  • These tackifiers come from petroleum-based feedstocks, primarily C5 resins and C9 resins. These tackifiers are typically solid at room temperature, and may have a softening point up to 150°C. Hydrocarbon resins are either aliphatic (C5), aromatic (C9), or mixed (a blend of C5 and C9).
  • Why do formulators use Tackifiers?
  • They are used to increase the tack or "stickiness" of the adhesive. In practice, formulators use tackifiers to make the correct balance between adhesion and cohesion which is dependent on the end-use application. They do this by lowering the modulus and increasing the glass transition temperature of the final adhesive.
  • What are neoprene Tackifiers?
  • Neoprene contact adhesives, in which phenolic resins are used to improve processing and heat resistance. In addition to modify tack, adhesion, and cohesion, tackifiers will affect other properties. These may be advantageous or disadvantageous to the formulator.
