PVOH
polymerPolyvinyl alcohol (PVOH) is a synthetic polymer produced by hydrolyzing polyvinyl acetate, characterized by its hydroxyl groups that provide water solubility and strong intermolecular hydrogen bonding. It is widely used in packaging films, textile sizing, adhesives, and pharmaceutical applications where water solubility, biodegradability, and good mechanical properties are advantageous; engineers select PVOH when they need a thermoplastic that can dissolve in water or degrade in aqueous environments, offering an alternative to petroleum-based plastics in environmentally sensitive applications.

Regulatory Screening
Environmental
Safety & Biocompatibility
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
