PVA, a water-soluble synthetic polymer, possesses excellent flexibility and processability. With advancing technology, different types of PVA have been developed to meet the requirements of various industries. As a versatile polymer material, PVA plays a crucial role in various Here are several common PVA types and their corresponding applications:

PVA Type: PVA-178

Application: PVA-178 is a highly soluble PVA type widely used in the textile industry for yarn coating and fiber reinforcement. Its exceptional adhesion and enhancing properties make it an ideal choice for the textile sector.

PVA Type: PVA-217

Application: PVA-217 is commonly used in the production of adhesives and glues. It exhibits excellent adhesion and moisture resistance, finding extensive applications in areas such as paper, pulp, ceramic tiles, wood, and paper-based packaging.

PVA Type: PVA-224

Application: PVA-224 is a special type of PVA primarily used as a modifier in coatings and paints. It offers good dispersibility and thickening properties, improving the viscosity and stability of coatings for easier application.

PVA Type: PVA-402

Application: PVA-402 is a cold-water soluble PVA type often employed in food packaging films. Its high solubility and water resistance make it an ideal choice in the food industry for packaging applications such as jelly films and food preservation wraps.

PVA Type: PVA-525

Application: PVA-525 is a highly crystalline PVA type primarily used in 3D printing and model making. Its excellent formability and solubility make it an ideal choice for rapid prototyping and soluble support material.
It is important to note that the examples provided above are only a few common PVA types and their corresponding applications. With the continuous advancements in science and technology, new types of PVA materials are continually being developed and introduced to cater to evolving industry needs.
