Product characteristics.

PVA 2488 is a white solid, and its appearance can be divided into flocculent, granular and powdery. Soluble in hot water. Its aqueous solution has good adhesion and film forming performance Film forming performance:

Pva 2488 is easy to film and has excellent mechanical properties. The tensile strength of the film increases with the increase of polymerization degree and alcoholysis degree. Generally, the higher the strength of the polyhedron

 

The role of the product.

This series of adhesives uses polyvinyl alcohol 2488 as the main raw material, and has good adhesion to paper, cloth and wood.

They have a wide range of uses, good adhesion and water solubility, and have a large market in the material bonding board, leather, decoration and other industries.

Product characteristics.

PVA 2488 is a white solid, and its appearance can be divided into flocculent, granular and powdery; It can be dissolved in water at 80-90 ºC. Its aqueous solution has good adhesion and film forming performance. Film forming performance.

PVA 2488 is easy to form film and has excellent mechanical properties. The tensile strength of the membrane increases with the increase of polymerization degree and alcoholysis degree.

PVA 2488 has good adhesion with hydrophilic cellulose. In general, the higher the degree of polymerization and alcoholysis, the stronger the bond strength. Thermal stability: When PVA 2488 is heated to about 100 ºC, its appearance gradually changes. The partially alcoholized polyvinyl alcohol starts to melt at about 190 ºC and decomposes at 200 ºC. The fully alcoholized polyvinyl alcohol 2488 starts to melt at about 230 ºC and decomposes at 240 ºC; The higher the alcoholysis degree, the shorter the decomposition time.

The role of the product.

PVA 2488 has good film forming performance, and the film formed has excellent adhesion and solvent resistance. It can be used together with cellulose ether humectant to improve the flexibility and water retention of cement mortar and gypsum building materials, improve mortar adhesion, reduce the amount of latex powder to a certain extent, and thus reduce the cost of dry powder doors.

Product characteristics.

PVA 2488 is a white solid. Its appearance can be divided into flocculent, granular and powdery: soluble in hot water. Its aqueous solution has good adhesion and film forming performance Film forming performance: PVA 2488 is easy to film and has excellent mechanical properties. The tensile strength of the film increases with the increase of polymerization degree and alcoholysis degree. Generally, the higher the degree of polymerization and alcoholysis, the stronger the bond strength.

The role of the product.

PVA 2488 has strong adhesion and film forming property. It can be used as a color carrier for coated paper, as well as a sizing agent for surface sizing of coated paper, wear-resistant paper, blueprint base paper, kraft paper, etc., replacing starch and casein or combining with it. It can improve the abrasion resistance, folding resistance, tear resistance, glossiness, smoothness and printing adaptability of the paper. PVA 2488 aqueous solution can replace water glass, starch or both for printing and binding, carton, cardboard, paper tube, etc.
