More about polyvinyl alcohols for PVC production
The role of polyvinyl alcohol in PVC production
Polyvinyl alcohol (PVA or PVOH) is used as a protective colloid in the suspension polymerisation of vinyl chloride. It helps stabilise the dispersed system and influences the formation of polyvinyl chloride particles.
This category covers grades for PVC production. Their intended use differs from finished adhesives and additives used to process PVC resin after polymerisation.
Grades in the REVADA Industrial catalogue
- WANWEI — grade 5-70.
- CHANG CHUN — grades BC-20, BC-24, TC-07H and TC-07P.
- SINOPEC SVW — grades FS-10, FS-20 and FS-20H.
The manufacturer sections list degree of hydrolysis and solution viscosity. Before selecting a product, verify the values, units and test methods against current technical documentation.
Grade selection
Compare the degree of hydrolysis, solution viscosity under specified conditions and the intended role within the suspending-agent system. Selection should reflect the polymerisation process and the required properties of the PVC resin.
A similar value for one parameter does not establish interchangeability. Determine dosage, component combinations and solution preparation procedures using manufacturer documentation and process trials.
