Selecting Plasticizers for Adhesives and Sealants
Plasticizers that are used in adhesive and sealant formulations are generally chosen on the basis of the following criteria: Compatibility with a given polymer or set of component ingredients Compounding characteristics Effect of plasticizer on the rheological properties of the polymer
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.

- How do I choose a plasticizer?
- The key evaluation parameters in choosing a plasticizer are: Plasticizers will reduce the melt viscosity of hot-melt adhesives and 100% solids adhesives & sealants. However, the addition of certain plasticizers to a polymeric emulsion will usually result in increased viscosity.
- Why should you choose a plasticizer that is compatible with polymer?
- By choosing a plasticizer that is compatible with the polymer, it protects the plasticizer for leaching out of the product and thus losing the benefits of plasticization. Plasticizer permanence, or resistance to migration out of the adhesive or sealant, plays a role in the longevity of a product.
- What is plasticizer compatibility?
- Plasticizer compatibility is the key to plasticizer performance in adhesives and sealants. In latex systems, compatibility can be assessed by observing the viscosity increase after the addition of the plasticizer and by observing the clarity of a cast film of the plasticized adhesives.
- What is a plasticizer used for?
- Plasticizers have been used to give polymers a permanent adhesive character (pressure sensitivity), or to regulate their adhesion-cohesion balance to achieve removability. For example, plasticizers can be incorporated into peelable pressure-sensitive adhesive to soften the adhesive, and thus improve peelability and clean removal.
- What types of plasticizers are used in adhesives & sealants?
- Oils (like paraffinic, naphthenic, and aromatic) are used mainly as plasticizers in non-polar adhesives. These are generally used in the hot-melt adhesives and sealants. Base polymers include the mid-blocks of styrene-butadiene copolymers and polyolefin-based adhesives. Polymeric plasticizers are used frequently in adhesives and sealants.
- Do plasticizers reduce the viscosity of adhesives & sealants?
- Plasticizers will reduce the melt viscosity of hot-melt adhesives and 100% solids adhesives & sealants. However, the addition of certain plasticizers to a polymeric emulsion will usually result in increased viscosity. This effect can be used to formulate a waterborne adhesive having greater coating thickness build-up.
