Polyvinyl Alcohol PVA 088-50 (PVA 2488)
Overview
PVA 088-50, 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
What is PVA 088-50?
PVA 088-50, a type of polyvinyl alcohol (PVA), this material is made from
vinyl acetate by alcoholysis reaction and polymerization; it is a white, powdery, stable, non-toxic
water-soluble polymer. It is a white, powdery, stable, non-toxic, water-soluble polymer with good water
solubility and can be quickly dissolved in room temperature water to form a stable colloid.PVA 088-50 also
has excellent film-forming properties, adhesion, solvent resistance, friction resistance, and tensile
strength.
What is PVA 088-50 used for?
In the construction industry, PVA 088-50 is used as an additive for adhesives such as cement, lime, and
mortar, significantly improving their adhesive strength.
In the iron and steel industry, PVA 088-50 is used as a quenching agent, an emulsifier for polyvinyl acetate emulsions, and a suspension and dispersing agent for
polyvinyl
chloride.
In the textile industry, PVA 088-50 can be used as a fabric finishing agent to improve the stiffness and
elasticity of fabrics.
In the paper industry, PVA 088-50 can be used as a color carrier or gumming agent for coated paper to
improve its physical properties.
In the dry mortar industry, PVA 088-50 can be used with VAE powder in the mortar of external wall
insulation to improve the adhesion and construction performance of mortar.
In addition, PVA 088-50 can also be made into a variety of adhesives, which are widely used in material
bonding boards, leather, decoration, and other industries.
How is PVA 088-50 packaged and stored?
Packages:20 kg/bag,25 kg/bag,500 kg/bag,1000kg/bag.
Storage: PVA 088-50 should be stored in a dry, ventilated environment at a controlled room temperature of
5-30°C and out of direct sunlight. Contact with chemicals should be avoided to prevent adsorption
deterioration.
What are the precautions for the use of PVA 088-50?
Although PVA 088-50 itself is non-toxic, appropriate protective equipment such as gloves and masks should
be worn during use to avoid prolonged skin contact or inhalation of its dust.
PVA 088-50 Meaning?
Polyvinyl Alcohol (PVA) 088-50 refers to a specific grade of polyvinyl alcohol, which is a synthetic polymer. Let's break down the meaning of
each component:
1. Polyvinyl Alcohol (PVA): PVA is a water-soluble synthetic polymer derived from
the polymerization of vinyl acetate, followed by the hydrolysis of the
resulting polymer. It is commonly used in a variety of applications due to its excellent film-forming and
adhesive properties. PVA is known for its biodegradability, non-toxic nature, and high tensile strength.
2. 088-50: This alphanumeric code typically represents the specifications and properties of the specific
grade of PVA. However, without more specific information, it is challenging to determine the exact meaning
of these numbers. Manufacturers often use such codes to convey details such as molecular weight, degree of
hydrolysis, viscosity, and other characteristics that vary depending on the desired application.
