Plasticizer Selection for Elastomers - Chemceed

Although majority of plasticizers are used in flexible PVC applications, a significant amount of plasticizers are used for elastomer applications. Plasticizers can be added to elastomers for various reasons: increasing softness or flexibility, lowering the glass transition temperature, reducing crystallization, increasing dispersion, or lowering the cost of the compound.

A secondary plasticizer is one that typically cannot be used as the sole plasticizer in a plasticized polymer. Secondary plasticizers may have limited compatibility with the polymer and/or high volatility. They may or may not contain functional groups which allow them to solvate the polymer at processing temperatures.

Natural-based plasticizers and biopolymer films: A review

In polymer science, plasticizers can be either defined as internal or external. External plasticizers are low volatile substances that are added to polymers. In this case, plasticizer molecules interact with polymer chains, but are not chemically attached to them by primary bonds and can, therefore, be lost by evaporation, migration or extraction.

In technical terms, the addition of a plasticizer generally causes a reduction in the cohesive intermolecular forces along polymer chains. The chains can then move more freely relative to one another, hence reducing the stiffness of the polymer. The use of plasticizers began in the mid 1860s when castor oil was added to Cellulose Nitrate.

What Plasticizers Do & How They Affect Properties

Approximately 90% of all plasticizers are used in polyvinyl chloride, or PVC. By volume, after Polyethylene (PE) and Polypropylene (PP), PVC is the third largest polymer used in products. PVC is one of the most durable materials in the world because of plasticizers added to it, lasting up to 50 years without damage.

Plasticizers are added to materials to make them softer and more flexible; some plasticizers are more efficient at this than others. Plasticizer efficiency is used to describe the ability of a plasticizer to make the product softer and is reported as a ratio of the slope of the hardness versus plasticized concentration to the slope of that found for DOP.

Polymer Additives and Their Functions

Plasticizers should generally have a solubility level close to that of the polymer itself, and multiple plasticizing additives can be used in a single mixture as long as they are compatible with each other and the polymer. When a plasticizer, such as dioctyl phthalate, is introduced to a polyvinyl chloride (PVC) polymer, it lowers its melt ..
