Suspension polymerization (PVC)
PVC is one of the most commonly used polymers worldwide and has outstanding properties, mainly due to its ability to absorb additives such as plasticizers. In the polymerisation process, Celopro® controls the particle size and porosity which is decisive for its additive absorbing behaviour.
An important characteristic of polyvinylchloride (PVC) is its ability to absorb additives, such as plasticizers, stabilizers, pigments, and impact modifiers, quickly and in sufficient quantities. However, the required porosity level is often obtained at the expense of bulk density. Using the appropriate suspending agent during polymerization allows the producer to maintain a balance of these properties.
