  • 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.
  • How to choose a plasticizer?
  • However, the plasticizer must be compatible with the base polymer and other additives in a formulation to function efficiently. Compatibility is the first and most important criterion for selecting a plasticizer. Within each family there are many variations. For example, there are over 30 different types of phthalates on the market.
  • 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.
  • What are plasticizers used for?
  • Plasticizers are the major functional additives transforming the physical properties of polymers such as PVC, PU, acrylic, nitrile and rubbers to create a whole world of flexible and durable finished articles for high demanding applications. The world plasticizer consumption was around 7.82 million MT in 2017, up nearly 25% over 6 years .
  • What is a tackifier in waterborne pressure-sensitive adhesive?
  • Tackifiers are important constituents in waterborne pressure-sensitive adhesives in terms of both cost and their effect on properties. Tackifiers get their name from the fact that they are used to increase the tack or “stickiness” of the adhesive.
  • Are plasticizers compatible with polymers?
  • They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear. A secondary plasticizer is one that typically cannot be used as the sole plasticizer in a plasticized polymer.
