PVA0388 product is a water-soluble polymer called polyvinyl alcohol, which is produced by cracking natural gas to obtain acetylene, and synthesizing acetylene with acetic acid to obtain vinyl acetate through gas phase synthesis. The vinyl acetate is then used as the raw material and subjected to special polymerization, modification, and various post-processing treatments.

Product Performance:
1. Film forming property: PVA0388 is easy to form a film, and its mechanical properties are excellent. The tensile strength of the film increases with the increase of polymerization degree and alcoholysis degree.
2. Protective colloid: PVA0388 plays a protective colloid role in the production of redispersible latex powder.
3. Thermal stability: When the PVA0388 flake is heated to around 100 ℃, the appearance gradually changes. Partial alcoholysis of PVA begins to melt at around 190 ℃ and decomposes at 200 ℃* The alcoholysis of PVA only begins to melt at around 230 ℃ and decomposes at 240 ℃. The thermal cracking experiment shows that the lower the degree of polymerization, the faster the weight reduction; The higher the degree of alcoholysis, the shorter the decomposition time.
