From the floor
A PVB customer audited our ash control on PVB-grade and signed an annual frame after seeing the retained-sample system.
QC bench
Every lot is checked on Shimadzu GC-2014C and Agilent AOC-20 gas chromatographs for volatiles/purity and a Brookfield DV2T viscometer for viscosity. Results travel with the COA.
Capacity and grade range
We make the full PVA range — 88 and 99 series, polymerization 300–3000, hydrolysis 75–100 mol%. 2488 (88% hydrolysis) is a standard, steady line, not a one-off.
Traceability
Each lot is sampled and kept to expiry; if a customer finds an issue we pull the same retained sample and the production record. That is the part traders cannot offer.
