An ink additive that adds flexibility, softness and adhesion.

(n) a substance added to plastics or other materials to make them more pliable

"A compound added to a polymer to make it softer and more flexible. These are usually small molecules with dangling bits that can disrupt the packing of polymer chains. A common plasticiser used to soften PVC is dioctyl phthalate:

Plasticisers are dispersants that are added to a material in order to increase it’s fluidity. An example of usage is concrete manufacture, where agents are added to increase workability of the wet mix and aid release of trapped air.

A plasticiser is a substance which when added to a material, usually a plastic, makes it flexible, resilient and easier to handle. Modern plasticisers are manmade organic chemicals; the majority of which are esters, such as adipates and phthalates. They are major components that determine the physical properties of polymer products. There are more [..]
