Polyvinyl Alcohol BP-17 is a type of polyvinyl alcohol (PVA) manufactured by Chang Chun Petrochemicals, a company based in Taiwan. PVA is a synthetic polymer that is water-soluble and has a range of applications due to its unique properties. It is created through the polymerization of vinyl acetate, followed by the hydrolysis of the resulting polymer to convert acetate groups into alcohol groups.

BP-17 likely refers to a specific grade or specification of polyvinyl alcohol produced by Chang Chun Petrochemicals. The naming convention of different grades often indicates variations in molecular weight, degree of hydrolysis, and other characteristics that can affect its performance in various applications.

Polyvinyl Alcohol (PVA) is commonly used in a variety of industries and applications, including:

1. Adhesives and Binders: PVA is used as an adhesive in woodworking, paper packaging, and other industries due to its water-soluble nature and strong bonding properties.

2. Textiles: PVA is used as a sizing agent in the textile industry to improve the strength and stiffness of yarns and fabrics.

3. Paper Industry: PVA is used to improve the strength, smoothness, and printability of paper.

4. Emulsifiers and Dispersants: PVA is used in the production of emulsions and dispersions in industries like paints, coatings, and cosmetics.

5. Packaging Films: PVA can be used to make water-soluble packaging films that dissolve in water, making them environmentally friendly for single-use applications.

6. Construction Industry: PVA can be used in cement-based products to improve their workability, adhesion, and overall performance.

7. Medical and Pharmaceutical: PVA is used in various medical and pharmaceutical applications, such as in the production of controlled-release drug delivery systems and as a component in certain medical devices.

8. Personal Care Products: PVA can be found in various personal care products like shampoos, lotions, and gels due to its ability to improve texture and viscosity.
