PVC 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 plasticisers.
In the polymerisation process MEICELL® 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 level of porosity 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.
MEICELL® cellulose ethers have been used as suspending agents for vinyl chloride polymerization.
These products are protective colloids made of linear polymers of condensed anhydroglucose rings that form a carbohydrate skeleton.
Methyl and hydroxypropyl groups are attached to the carbohydrate skeleton via an ether linkage.
MEICELL® cellulose ethers are nonionic, surface-active film formers.
When used as suspending agents in vinyl chloride polymerization, they provide particle size control, uniform particle size distribution, and porosity that can be optimized for many PVC end-uses.
This publication discusses the use of MEICELL® cellulose ethers as suspending agents for vinyl chloride polymerization.
