  • What is a plasticizer?
  • A plasticizer is a non-volatile substance incorporated in a plastic or elastomer. It changes the thermal and mechanical properties of the material. The expected property changes in a plasticized plastic or elastomer are as follows: Plasticization is classified into two main groups such as internal and external.
  • Why are plasticizers a good material?
  • Consequently, materials containing plasticizers tend to exhibit enhanced mechanical properties, such as greater elongation at break and reduced brittleness, making them suitable for applications requiring durable yet flexible materials.
  • How do Plasticizers improve the properties of a polymer?
  • They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer. This is done by decreasing the viscosity of the polymer melt, Tg, Tm, and elastic modulus of the finished product.
  • What is a primary plasticizer?
  • 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.
  • Why are plasticizers used in film coating?
  • Plasticizers are low molecular weight substances added to a polymer solution to promote its plasticity and flexibility. Therefore, the plasticizers make the polymer solution more suitable for the application of film coating. There should be chemical similarities between the polymers and its plasticizers.
  • What is plasticizer efficiency?
  • Plasticizer efficiency denotes a plasticizer's capacity to impart softness to the product. It is quantified as a ratio of the slope in the hardness-versus-plasticizer-concentration relationship. This correlation expressed in phr (parts per hundred resin), is depicted in Figure 4. Several types of plasticizers mentioned in the graph include:
