plasticize

To plasticize means to make a material more plastic, which means softer, more flexible, and easier to shape. The word is mainly used in technical, industrial, and scientific contexts. A common example is treating rubber, clay, or a synthetic material so that it can be bent, pressed, rolled, or formed more easily. Often this happens by adding a plasticizer, a substance that reduces stiffness and makes the material less brittle.

This is the central use of the word. In manufacturing, a company may plasticize a material so it can be turned into tubing, flooring, seals, or other finished products. In lab or workshop settings, the word can also describe changing the texture of a substance so it handles better during processing. For example: "The maker plasticized the rubber before shaping it." In this sense, the word is about improving flexibility and workability, not about turning something into plastic in the everyday sense.

The idea can sometimes be extended to any process that makes a substance more moldable, but it usually stays close to physical materials rather than abstract ideas. If you see plasticize in real use, it will most often refer to making a material easier to form, especially by chemical treatment or by mixing in an agent that softens it.
