Polyvinyl alcohol (PVA) is a versatile polymer with various applications due to
its unique properties. PVA 100-27 is a specific grade of PVA that refers to
its degree of hydrolysis and viscosity. Here are some common applications of PVA 100-27:
1. Adhesives: PVA 100-27 is widely used as an adhesive in various industries. It forms a strong bond
between different materials such as paper, cardboard, wood, and textiles. PVA-based adhesives are commonly
used in woodworking, packaging, bookbinding, and labeling applications.
2. Textile Industry: PVA 100-27 finds applications in the textile industry as a sizing agent or a warp
sizing agent. It provides temporary stiffness and improved handling properties to yarns during weaving or
knitting processes. PVA-based sizes are easily washed off during subsequent processing.
3. Paper Coating: PVA 100-27 is utilized in paper coatings to improve the surface properties of paper. It
enhances the smoothness, printability, and ink absorption capacity of coated papers. PVA-based coatings
are commonly used in glossy magazines, catalogs, and high-quality printing papers.
4. Film Formation: PVA 100-27 can be used to produce thin films through the process of film formation.
These films possess excellent barrier properties against gases and solvents, making them suitable for
applications such as food packaging, pharmaceutical packaging, and water-soluble pouches.
5. Emulsifiers and Stabilizers: PVA 100-27 is used as an emulsifier or stabilizer in various industries,
including the cosmetics, personal care, and pharmaceutical sectors. It helps to stabilize emulsions and
suspensions, improving their viscosity and preventing phase separation.
6. Mold Release Agent: PVA 100-27 can act as a mold release agent in various molding processes, including
resin casting, fiberglass, and rubber molding. It forms a thin film between the mold surface and the
molded object, allowing for easy release without damaging the final product.
7. Construction: PVA 100-27 is utilized in the construction industry for applications such as cement
additives, mortar modifiers, and tile adhesives. It enhances the workability and adhesion properties of
construction materials, improving their performance and durability.
8. Soil Stabilization: PVA 100-27 can be used in soil stabilization applications. When mixed with water,
it forms a gel-like substance that can improve soil cohesion and stability. This property is particularly
useful in construction projects, erosion control, and agricultural applications.
