Selecting Tackifiers for Adhesives and Sealants
Functions of Tackifiers In adhesive and sealant formulations, tackifiers are used to generate tack and improve specific adhesion (peel strength). They are incorporated into base polymers which mainly lack tackiness and pressure-sensitive properties but provide cohesion.

Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
- 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 are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- How to choose a general-purpose plasticizer for PVC?
- While selecting a general-purpose plasticizer for PVC, the main attributes to be checked are: Among them, regulation is an important decision factor while selecting plasticizers. In recent years, there has been a lot of discussion on phthalate plasticizers. But in fact, not all phthalates are prohibited.
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. 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.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
