For PVC - Production (Suspension Polymerization)

There are several processes for producing PVC, one of which is suspension polymerization. 

HPMC - Hydroxypropyl Methyl Cellulose (ARBOCEL® CE) is beside Polyvinylalcohol (PVA) one of the most commonly used suspending agents.

ARBOCEL® CE controls the particle size and their distribution, influences the porosity and defines the bulk weight of PVC. The porosity of the polymer particles is strongly linked to the property to adsorb additives like e.g. plasticizers or stabilizers. Thereby, the properties of the polymer during processing and of the final product can be controlled. 

Ultra low viscous ARBOCEL® CE is the most suitable product for PVC manufacturing processes. Methoxy and hydroxypropyl substitution levels and the viscosity determine the performance characteristics as a PVC suspending agent. Besides this, the particle size of ARBOCEL® CE  is specially designed to dissolve perfectly for a smooth PVC polymerization process.
