Manufacturing Process For Poly Vinyl Acetate In Wikipedia

Manufacturing Process For Poly Vinyl Acetate In Wikipedia; Polyvinyl acetate Wikipedia. Poly(vinyl acetate) was discovered in Germany in 1912 by Fritz Klatte. The monomer, vinyl acetate, was first produced on an industrial scale by the addition of acetic acid to acetylene with a mercury(I) salt but it is now primarily made by palladium catalyzed oxidative addition of acetic acid to ethylene.

Casting Process - an overview

The process can be modified to allow continuous pipe production. There is a modified centrifugal casting process that produces continuous filament reinforced TP pipes/tubes with precise fiber placement and smooth internal and external surfaces. TPs such as nylon and polypropylene have been reinforced with fibers such as glass and carbon.
