Product Description
Polyvinyl alcohol PVA224
1. PVA description
PVA resin is a kind of high polymer, it is odorless, non-toxic, water-soluble, excellent film forming
CAS Number: 9002-89-5
EINECS: 209-183-3
Appearance: White powder; white granular; Floc
Chemical Formula: [CH2CHOH]n ; or -[CH2CHOH]n-[CH2CHOOCCH3]m-
Synonyms: Polyvinyl alcohol; PVA resin; PVOH
Flash point: 79ºC
Specific gravity: 1.19-1.31
Usages: The polyvinyl alcohol additive contributes to cost savings and has shown no retardation effect on the cement setting time. Therefore, it enables fast and cost-efficient oil well construction.
when pva224S mixed with cement powder, water, dispersant and defoamer, will prevent fluid loss to the formation in cementing operations. it is an excellent binder, reduces fluid loss, reduces water production in the cementing process and compatible with other cement additives. It contributes to cost savings by enabling fast and cost-efficient oil well construction and has shown no retardation effect on the cement setting time
