Selecting Plasticizers for Adhesives and Sealants
Plasticizers are one of the commonly used additives in adhesives and sealants formulations. They improve the performance of adhesives by creating much-needed flexibility, optimizing viscosity, toughness, set time functionality, impact resistance, and even adhesion.

Jayflex high-molecular-weight plasticizers provide an optimum balance of properties with outstanding performance and permanence. Adipate plasticizers Jayflex adipate plasticizers can be used as a primary plasticizer but, more typically, are used in blends with general-purpose phthalates to improve low temperature properties.
Plasticizers: Types, Uses, Classification, Selection & Regulation
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.

Bio-Based Plasticizers Stretch Production Capability
Highly efficient plasticizers can reduce the total amount or loading of plasticizer, which can lower costs and reduce potential for compatibility issues. Cold Temperature Flexibility: When polymers experience lower temperatures, they generally become stiffer and brittle. Plasticizers can lower the temperature when this starts to occur.
- What is an ester plasticizer?
- An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.1 For general performance applications, compounders require moderate performance in several areas without particular emphasis on any one.
- Why are plasticizers added to ca?
- Plasticizers are added to CA to increase workability, prevent degradation under processing conditions and ensure thermo-mechanical properties suitable for the intended final application. Moreover, inexpensive and non-toxic solvents enable its processing into fibers, films, and solid blocks.
- What are plasticizers & how do they work?
- Plasticizers are non-volatile organic substances (mainly liquids) added into a plastic or elastomer. They are also usually cheaper than other additives. They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer.
- Which plasticizer has a good plasticizing efficiency?
- Both plasticizers provided a satisfactory plasticizing efficiency, such as DEP, due to their low viscosity and ease of diffusion into CA, which enables a large processing window and increases the material's flexibility. CA with 30 wt% GTA displayed a slightly higher elastic modulus than CA with 30 wt% GDA (E = 2.1 GPa and 1.9 GPa, respectively).
- What are low molecular weight plasticizers?
- Low molecular weight plasticizers are added before or during the processing to reduce the melt processing temperature. However, these low molecular weight plasticizers may have some drawbacks, such as volatility, high water solubility, and insufficient compatibility with CA.
- How to choose a high-performance ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer. 1.
