Product Application

PVA2099 Introduction:

     - "20" in PVA2099 means that the degree of polymerization is about 2000, and "99" means that the degree of alcoholysis is 99%.

     - The appearance is white flake, flocculent or powdery solid.
    - It needs to be dissolved in high-temperature hot water, and its aqueous solution may gel under certain conditions.

PVA2099 Application:

    - Textile field: used as textile pulp to enhance the strength and wear resistance of yarn, improve loom efficiency and fabric quality.
   
    - Adhesive industry: It can be used to make high-performance adhesives for bonding materials such as wood, paper, and plastic.
   
    - Papermaking industry: As a papermaking auxiliary agent, it improves the strength and toughness of paper.
   
     - Building materials: Used to prepare some special building materials, such as waterproof glue.
