Plasticiserende

Plasticiserende is a term used in chemistry and materials science to describe the process of making a substance more plastic or moldable. This is typically achieved by adding a plasticiser, which is a substance that increases the plasticity or fluidity of a material. Plasticisers work by reducing the intermolecular forces between the molecules of the material, allowing them to move more freely. This results in a softer, more flexible, and easier-to-work-with substance.

The most common application of plasticisers is in polymers, particularly polyvinyl chloride (PVC). Unplasticised PVC is a rigid material, but by adding plasticisers, it can be made flexible enough to be used in applications like cables, flooring, and films. The type and amount of plasticiser used will determine the final properties of the plasticized material. Different plasticisers have varying compatibilities with different polymers and can affect properties such as flexibility, durability, and chemical resistance.

Beyond polymers, plasticising principles can be applied to other materials. For instance, in clay-based materials like ceramics or pottery, water acts as a plasticiser, allowing the clay to be shaped before firing. In some food products, ingredients might be added to improve texture and mouthfeel, a form of plasticising. The concept is fundamentally about enhancing deformability and workability by reducing internal resistance to deformation.
