polyvinyl acetate - FRP BMC/SMC

タイトルまたは説明

polyvinyl acetate (pvac) can be largely used in BMC/SMC in FRP industry.  polyvinyl acetate (pvac) .

pvac, Polyvinyl acetate, PVAC is a rubbery synthetic polymer with the formula (C4H6O2)n. PVAC belongs to the polyvinyl esters. pvac is largely used in food and industry application. PVAC will play an important role in today's industry.

Polyvinyl acetate, PVA, PVAc, poly(ethenyl ethanoate), is a rubbery synthetic polymer with the formula (C4H6O2)n. It belongs to the polyvinyl esters family with the general formula -[RCOOCHCH2]-. It is a type of thermoplastic.

It should not be confused with the related polymer polyvinyl alcohol, which is called PVA also (PVAc could be considered a technically correct abbreviation for polyvinyl acetate and would aid in avoiding such confusion).

Polyvinyl Acetate is a component of a widely-used type of glue, referred to variously as wood glue, white glue, carpenter's glue, school glue or PVA glue. Addictives to glass fiber reinforced plastics for automobile light cover, and mixed with cement to form a stable concrete in floor decking.
