Product Description
PVA/Polyvinyl alcohol, organic compound, white flake, flocculent or powder solid, odorless.Dissolved in water. Slightly soluble in dimethyl sulfoxide. Polyvinyl alcohol is an important chemical raw material used to make polyvinyl polymer, gasoline-resistant pipes and vinylon synthetic fibers, fabric treatment agents, emulsifiers, paper coatings, adhesives,glues, etc.
Polyvinyl Alcohol PVA
It is a water-soluble polymer obtained by hydrolysis of polyvinyl acetate (PVA).It is a white or slightly yellow powder/granular solid that is non-toxic, odorless, and has good film-forming, bonding, and chemical stability.
1. Film forming property
It forms a transparent, tough film with good mechanical strength and airtightness.
2.Adhesion
It has good adhesion to cement and other gelling materials.
3.Chemical Stability
It has good oil and solvent resistance and excellent biodegradability.
4.Solubility
It can be dissolved in cold or hot water (depending on the degree of hydrolysis) to form a transparent glue.
5.Emulsifying Thickening Properties
It can be used as an emulsion stabilizer and rheology modifier.
6. High Slump Retention Capability
High slump retention capability refers to the ability of concrete to maintain its initial workability (flowability, cohesiveness, and water retention) for an extended period during mixing, transportation, pumping, and pouring, without experiencing bleeding, segregation, or severe drying. High slump retention capability is achieved through the use of high-quality polycarboxylate ether superplasticizers, providing superior retention for up to 4 hours, ensuring smooth construction.
