Henan Jinhe Industry CO.,LTD extended our manufacture line to more series pigments such as Carbon Black ,Iron Oxide and chrome pigments by share&join brother factories ,Further more,
,we have special advantage on Pvc Resin, PVC Paste Resin, PVA,we are forwarder of many famous Enterprise in China, such as Sinopec, LB Group, Doguide,ANADA, PANGANG, Zhongtai Chemicals,Tianye Group, CCP Suzhou,Erdos and Junzheng Group
Polyvinyl alcohol Resin series products are white solid,appearance divided into flocculent, granular, powder three kinds; Non-toxic tasteless, no pollution, PVC can be dissolved in 80- 90℃ water. Its aqueous solution has good adhesion and film forming property. Most organic solvents such as oils, lubricants and hydrocarbons; It has the chemical properties of esterification and acetalization of long chain polyols.our brand are Shuangxin,SUNNY, Wanwei.
Polyvinyl alcohol PVA100-84
(1) Film formation
PVA 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) adhesion
PVA has good adhesion with hydrophilic cellulose. In general, the higher the degree of polymerization and alcoholysis, the stronger the bonding strength.
(3) Thermal stability
When the powder of polyvinyl alcohol was heated to about 100℃, its appearance gradually changed. Partial alcohololysis of PVA begins to melt at about 190℃, and decomposition occurs at 200℃. The PVA of complete alcoholysis begins to melt at about 230℃ and decompose at 240℃. The pyrolysis experiments show that the lower the degree of polymerization, the faster the weight reduction; The higher the alcoholysis degree, the shorter the decomposition time
