Polyvinyl Alcohol (PVA) – LR Grade, 500g

Polyvinyl Alcohol, sometimes referred to as Ethenol, is a versatile synthetic polymer supplied in a 500g pack and manufactured to Laboratory Reagent (LR) grade. With an approximate molecular weight of 17,000, this grade of PVA is ideal for consistent, reliable results in educational laboratory applications.

Identified by CAS Number: 9002‑89‑5 and carrying no UN number, Polyvinyl Alcohol is not classified as hazardous for transport when handled appropriately. It is a water‑soluble polymer that forms clear, flexible films and gels, making it particularly suitable for practical demonstrations linking chemistry, materials science, and physics.

Easy to dissolve in warm water and simple to store, this larger 500g pack is well suited to schools and colleges carrying out repeated experiments or whole‑class practical activities.
