Polyvinyl Alcohol (PVA) 100-78 & PVA 2699S
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
PVA, categorized as a polyvinyl alcohol (PVA), is produced through an alcoholysis reaction and subsequent polymerization of vinyl acetate. This material manifests as a white, powdery substance, characterized by stability and non-toxicity, and it exhibits remarkable water solubility. When introduced to water at room temperature, it readily dissolves to create a stable colloid.

Frequently Asked Questions
Polyvinyl Alcohol (PVA) 100-78 & PVA 2699S Applications
Processing and Finishing Agent
Polyvinyl alcohol has become the core component of textile finishing agents due to its strong film-forming properties, interfacial adhesion and environmental adaptability. Its role is not limited to improving physical properties (crispness, wear resistance) but also giving fabrics functional properties through chemical modification (acetalization).
Paper Processing
n paper processing,
polyvinyl
alcohol
becomes a multifunctional
additive
that improves the
comprehensive
performance of paper
through the
three-in-one mechanism of
"surface film
formation-pigment
bonding-fiber
reinforcement".
It
has great advantages in
terms of
strength, printability,
water
resistance and
environmental
protection, and is
especially
irreplaceable in high-end
paper
and
specialty
paper.
Adhesive
Polyvinyl alcohol in adhesives has become a multi-scenario bonding solution through the three-in-one mechanism of "polar adhesion-film enhancement-chemical modification". Its core value lies in safety and environmental protection, broad-spectrum bonding, and easy modification, and it is especially suitable for cellulose substrates.
Forming Board Adhesive
Polyvinyl alcohol has become the core adhesive in molding board adhesives due to its high bonding strength, adjustable water resistance and environmental safety. It is particularly suitable for scenes such as gypsum boards and wood chip boards that require both mechanical properties and environmental friendliness.
