PVA , one of the grades of PVA
Haoshuo Product Page
PVA stands for polyvinyl alcohol, which is a polymeric compound that is soluble in water. PVA was first developed in Germany by the Nobel Laureate Dr. Hermann Staudinger, and further developed in Japan. It's usually found in bead or solution form on the market, and industrially it can be made through the hydrolysis of polyvinyl acetate or any other vinyl ester derived polymer belonging to the formate or chloroacetate group.
There are different grades of PVA sold on the market. This could occur due to different levels of polymerization during the making process. Although it seems that these different types are the same chemical, they are suitable for different purposes. Here we list some of the PVA sold on the market and their specifications:
PVA is known to be used as an adhesive material due to its high tensile strength and its ability to be solved in water. It is similar to natural adhesive material, such as dextrin and casein. However, PVA has the advantage of being more adhesive and has more stable chemical structure. This allows PVA to be used minimally when used as adhesive material.
Generally, PVA and PVA are used for adhesive purpose. It is used as adhesive or glue for office purpose, paper, wood, textiles, and coating base material.
PVA Film is a film that is water soluble and biodegradable due to the properties of PVA. Although PVA is soluble in water, it is hard to dissolve in other chemicals, especially organic solvents. This makes PVA film a good choice to package chemical products such as detergents, agrochemicals, dyes, fertilizers, and water treatment chemicals.
PVA Film
To produce PVA Film, generally, PVA , PVA , PVA , PVA , and PVA are used.
Water-soluble polymers are used in various processes in the paper making industry. PVA is usually used as a binding agent, re-moisturizing agent, pigment coating, and surface sizing agent. Starch and casein were originally used as surface sizing and binding agents respectively. However, PVA is now being used due to it being more efficient to use.
Paper Making Industry
For paper making industry, PVA , PVA , and PVA are generally used
PVA is typically used as the binding agent for plywood and timber processing. In these processes, resins such as melamine, formaldehyde, and carbamide are typically used. If PVA is used in these resins, it could increase the viscosity and shorten the curing and cooling time of the resin. The addition of PVA will also increase the initial cohesion of the resin.
For this purpose, PVA , PVA, , and PVA are commonly used.
In construction, PVA could be added to the cement mortar mix. The addition of PVA could increase the waterproofing qualities and the adhesion capability of the mixture to a surface. Other than being mixed into the cement mortar mixture, PVA could also be painted onto a surface before the mixture is applied to further increase the adhesion.
Cement Mixture in Construction
As building adhesive, PVA , PVA , PVA , and PVA are used for this purpose.

PVA is used in the preparation, printing, dyeing, and finishing processes in the textile industry to carry out these processes more efficiently. Here are the reasons why PVA is used as a textile auxiliary:
PVA and PVA are used for this purpose.
An emulsifying agent is a chemical that stabilizes an emulsion, which allows a mixture of liquids that commonly don’t mix to separate. PVA is used in the production of Vinyl Acetate Homopolymer (PVAc) emulsion. In the production of this emulsion, PVA is added to a mixture of polymerized, colloidal, and granular PVAc and a solvent. This result in an emulsion that is stable and prevents the emulsion from degrading.
For this purpose, PVA , PVA , PVA , PVA , and PVA are used.
PVA can be used to make PVA fibers, which can be used for various purpose. PVA fiber can be modulated to have medium to high strength, and can have various other characteristic, such as being water soluble. One of the examples of PVA fiber is Vinylon.
Vinylon is a type of synthetic fiber made with PVA, anthracite, and limestone. As a textile material, vinylon has the advantage of being highly resistant to heat and chemicals. However, it is no longer widely used in the textile industry due to its stiffness, difficulty in dyeing, and high manufacturing cost. It is still used in the textile industry to manufacture work clothes and uniforms.
Vinylon Yarn
Other than the textile industry, Vinylon can also be used to produce fish nets and as an alternative to asbestos due to its high resistance and high strength. To produce PVA fiber, PVA , PVA , PVA , PVA , and PVA are used
PVB, also known as Polyvinyl Butyral, is a colorless compound made from the condensation of PVA and butyraldehyde. It has various uses, but the most common application is to manufacture laminated glass, which is glass that could hold itself together when breaking. This glass usually used for vehicles glasses and windows. Its other uses are for bulletproof material and for photovoltaic thin film for solar panels. The most common PVAs that is used for this purpose are PVA , PVA , PVA , PVA , and PVA .
PVA is available in various packaging. At Camachem, we package PVA typically in:
PVA in 50 Kg Sealed Bags
To store PVA, it is recommended to store it in a waterproof storage facility, as PVA can quickly degenerate once it is mixed with water. This degeneration happened due to activity of bacteria. When storing the paste of PVA, it is advised to use a stainless-steel container, as corrosion may occur in an iron or steel container. If stainless steel container is not available, an application of 0.05% sodium benzoate or sodium nitrate can be done to the PVA paste to avoid the corrosion process.
Since PVA quickly degenerates once mixed with water, it can be difficult to store it in liquid form. If storage in liquid form is needed, 0.01-0.05% of an antiseptic, such as salicylic acid, can be added.
