Wanwei Polyvinyl Alcohol (PVA)
The "Wanwei" brand polyvinyl alcohol (PVA) series products manufactured by Anhui Wanwei Group Co.,Ltd are produced using advanced technology and processes. Specifically, they are made from either vinyl acetate produced via the calcium carbide acetylene method or the petroleum ethylene method, or from ethylene derived from bio-ethanol, using methanol as a solvent and a peroxide as an initiator, through polymerization and hydrolysis processes.
