Product Application

   PVA05-88 is briefly introduced as follows:

      - Physical properties: It is a white powder or granular solid, odorless and non-toxic. The relative density is between 1.27-1.31, the refractive index is 1.49-1.52, the thermal conductivity is 0.2w/(m·K), the specific heat capacity is 1-5J/(kg·K), and the resistivity is (3.1-3.8)×107Ω·cm.

      - Solubility: It is easily soluble in water, and has better solubility in hot water. It can be completely dissolved when heated to 65-75ºC. Its aqueous solution has good film-forming and adhesion 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 it will decompose or react chemically under high temperature, strong acid, strong alkali and other conditions.
 
     - Uses: In the papermaking industry, it is used as a paper surface sizing agent, pigment processing agent and internal sizing agent to improve the printing adaptability of paper and other properties; in the textile industry, it is used as a warp yarn sizing agent to make the warp yarn smooth and smooth and reduce the breakage rate of the cloth machine; in the field of adhesives, its aqueous solution has strong adhesion to materials containing cellulose and can be used for various bonding purposes such as cardboard lamination; it can also be used to prepare , which is widely used in construction, coatings and other fields.
