Product Application

PVA1588 Introduction:

     
- Basic information:
     

       The "15" in PVA1588 means that the degree of polymerization is about 1500, and the "88" means that the degree of alcoholysis is about 88%.

    - Physical properties:
       
   
  It appears as a white powder or granular solid, odorless and non-toxic. The relative density is between 1.27-1.31, and the refractive index is 1.49-1.52.

      - Solubility:
        
   
 Easily soluble in water, and more soluble in hot water. Its aqueous solution has good film-forming and adhesive properties.

      - Chemical properties:
      
     
It has chemical reactivity such as esterification, etherification, and can react with a variety of substances to generate compounds with different properties and uses.
     
     
- Stability:
     
    
It is stable at room temperature, but decomposes or reacts chemically under high temperature, strong acid, strong alkali and other conditions.
     
   
 - Uses:
 

   It is used as a paper surface sizing agent in the papermaking industry, as a warp yarn slurry in the textile industry, and can be used for various bonding purposes such as cardboard lamination in the adhesive field. It can also be used to prepare polyvinyl alcohol , which is widely used in construction, coatings and other fields.
