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.
Eastman Plasticizers for Adhesives
Benzoflex LA-705 is a benzoate ester plasticizer formulated specifically for use in latex adhesives. It provides a unique combination of high performance, broad food contact approvals, and reduced EU labeling requirements. Product availability by region: Asia Pacific | Europe, Middle East, & Africa | Latin America | North America
Binder for High Performance Sealants - Arkema
latex, ASTM C920 Class 35 performance can be achieved without the need for external plasticizer at a pigment/binder ratio of 1.2. External plasticizer may be employed with ENCOR 167S latex to achieve desired performance at higher pigment to binder ratios. Tensile-Elongation Comparison Figure 7 is a comparison of the tensile-

Some plasticizers develop a high potential regarding scope of use, but they are designed for a specific use. Unimoll AGF, our largely bio based plasticizer, was developed for the use in articles intended to come into contact with foodstuffs. Our Uniplex Benzoates are mainly solid special plasticizers used in hot-melt adhesive & equipment
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.
- 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.
- What are velsiflex plasticizers?
- Velsiflex plasticizers are high performance plasticizers. They are polar and monomeric in nature. In most cases, they provide superior performance compared to other plasticizers as it relates to polymer compatibility, efficiency and desired softness.
- 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.
- 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:
- Is velsiflex a plastisol?
- As a vinyl plasticizer, Velsiflex® has the solvating power that affords ample formulating latitude for optimized PVC formulations. Typical plastisol applications include calendering, flooring, or automotive plastisol sealants. Velsiflex plasticizers are high performance plasticizers. They are polar and monomeric in nature.
- What is velsiflex 332 Plastisol?
- It also improves adhesion to acrylic latex caulks and is a high-solvating PVC plastisol. Velsiflex 332 is a mixture of benzoate esters that perform as a high solvating plasticizer. With exceptional performance in PVC, Velsiflex 332 provides lower processing temperatures for various plastisol applications from flooring to sealants.
