Engineering Detail

A European-sourced secondary PVA option.

Alcotex 552p offers PVC producers a qualified secondary PVA source with well-documented behaviour in European PVC-S reactor designs. Its low hydrolysis level is chosen to develop PVC particle internal porosity without destabilising the primary suspension. We offer it as an alternative or blend partner to POVAL L-series and KH-17 — useful when spec-qualification or dual-sourcing requires a European origin rather than Japanese.

European origin

For buyers needing EU-sourced PVA to diversify away from Japan/China — supported by Synthomer technical data.

Porosity tuning

Low hydrolysis level drives PVC internal porosity — critical for compound-grade resin plasticiser uptake.

Drop-in replacement

Qualified substitute for other European and Asian secondary PVA grades in standard PVC-S formulations.

Technical backup

Our chemists help you set primary/secondary PVA ratios for S65, S70, and S1000 resin targets.
