Product description
Ultimaker Pva Resin VS Hips
Vinyl acetate (CH2=CHO2CCH3) is prepared from ethylene by reaction with oxygen and acetic acid over a palladium catalyst. Under the action of free-radical initiators, vinyl acetate monomers (single-unit molecules) can be linked into long, branched polymers (large, multiple-unit molecules).
Polyvinyl Acetate (PVAc), a synthetic resin prepared by the polymerization of vinyl acetate. In its most important application, polyvinyl acetate serves as the film-forming ingredient in water-based (latex) paints; it also is used in adhesives.
