A plasticizer by itself can also reduce the modulus of the polymer network, but it is ineffective in increasing the tack, as it decreases the Tg of the system. Tackifiers with higher melting point should be added early in the
agents, stabilizer, inhibitors, plasticizers and the like. The polymerization and formulation process can be carried out in a solvent, which would be removed to produce 100% solids hot melt

Peel Adhesion to PVC: The formulation should have strong adhesion to PVC but be designed for clean removal, requiring a careful balance of rubber, tackifiers, and plasticizers. Here's a formulation for a rubber-based, solvent-based PSA suitable for PVC electrical insulation tape, designed to offer high cohesive strength and clean removal with

- 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.
- Are Tackifiers compatible with a base polymer?
- In order to effectively provide these modifications, tackifiers must be compatible or partially compatible with the base polymer. The first and most important criterion in the selection process is the compatibility between the tackifier and the base polymer in the adhesive formulation.
- 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.
- Can acrylic based PSAs be tackified?
- Tackifying an acrylic based PSA can expand the performance window and/or give the system a more robust response to substrates of different surface energy. The use of tackifying resins in acrylic PSAs is a valuable tool for the adhesive formulator. However, the selection of viable candidates is limited.
- How many types of Tackifiers are there?
- There are hundreds of tackifiers available commercially. Rosin ester tackifier resins were used in early pressure sensitive adhesive formulations, but they have largely been replaced by better aging terpene resins which provide excellent performance characteristics.
- Which tackifier is used in acrylate polymers?
- For low surface energy adhesion applications, a tackifier is typically used in acrylate polymers. Rosin esters, preferably hydrogenated rosin esters, have been proven to be compatible and effective. Hydrocarbon C5 and C9 tackifiers may also be considered. The loading of the tackifiers may range from about 10-30% of the total formulation.
