Frequently Asked Questions

PVA 088-35 Relationship with PVA

Polyvinyl Alcohol (PVA) 088-35 is a specific grade or variant of PVA. PVA is a synthetic polymer that is water-soluble and can be used in various applications due to its unique properties. It is created through the polymerization of vinyl acetate, followed by hydrolysis to remove the acetate groups. The degree of hydrolysis determines the properties of the resulting PVA.

PVA 088-35 refers to a specific grade or specification of PVA. The numbers in the name indicate certain characteristics of the polymer. In this case, "088" typically refers to the degree of hydrolysis, indicating that approximately 88% of the acetate groups have been replaced with hydroxyl groups. This degree of hydrolysis affects the water solubility, crystallinity, and other properties of the PVA.

The "35" in PVA 088-35 may refer to the molecular weight of the polymer. Higher molecular weights generally result in increased viscosity and film-forming properties of the PVA.

In summary, PVA 088-35 is a specific grade of PVA with a particular degree of hydrolysis and potentially a specified molecular weight.

What is PVA 088-35 & PVA 2088 used for?

PVA 088-35 & PVA 2088 is primarily used as an adhesive in the printing and textile industries, as well as for reducing removal during the sizing and weaving process to maintain factory cleanliness, as fiber reinforcement in concrete, as an agent in medical procedures, and in eye drops and hard solutions.

How is PVA 088-35 & PVA 2088 packaged and stored?

Packing: PVA 088-35 & PVA 2088 is packed in paper bags with a weight of 20kg per package.
Storage: PVA 088-35 & PVA 2088 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 088-35 & PVA 2088?

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.
