Adhesion: PVA 2488 has good adhesion with hydrophilic cellulose. Generally, the higher the degree of polymerization and alcoholysis, the stronger the bonding strength.
Product advantages
The film made of polyvinyl alcohol 2488 has good transparency, high tensile and crack resistance, good moisture permeability and heat insulation, oil resistance, organic drug resistance, and no static electricity, so it is actually used for textile packaging. It can also be used as food packaging, non-toxic, tasteless, pollution-free, and biodegradable. In addition, it can be compounded with polyethylene, polypropylene, etc., and used as instrument packaging, printing and plate making.
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 ℃. Its aqueous solution has good adhesiveness and film-forming property;
Film forming property: PVA 2488 is easy to form film, with excellent mechanical properties. The tensile strength of the film increases with the increase of polymerization degree and alcoholysis degree.
Adhesion: PVA 2488 has good adhesion with hydrophilic cellulose. In general, the higher the degree of polymerization and alcoholysis, the stronger the bonding strength.
Thermal stability: When polyvinyl alcohol 2488 is heated to about 100 ℃, its appearance gradually changes. The partially alcoholized PVA began to melt at about 190 ℃ and decomposed at 200 ℃. The completely alcoholized polyvinyl alcohol 2488 began to melt at about 230 ℃ and decomposed at 240 ℃. The pyrolysis experiment showed that the lower the polymerization degree, the faster the weight reduction; The higher the alcoholysis degree, the shorter the decomposition time.

Product advantages
Polyvinyl alcohol 2488 has strong adhesion and strong film forming. It can be used as a color carrier for coated paper or as a sizing agent for surface sizing of copperboard paper, wear-resistant paper, blueprint base paper, kraft paper, etc., instead of starch and casein or in combination with it. It can improve the abrasion resistance, folding resistance, tear resistance, gloss, smoothness, and printing adaptability of paper. PVA 2488 aqueous solution can be used instead of water glass, starch or both for printing and binding, carton, cardboard, paper tube, etc.

Product advantages
The sizing agent mainly composed of polyvinyl alcohol 2488 is a synthetic sizing agent and fabric processing agent with the highest efficiency among sizing agents. It has good adhesion to cotton, linen, polyester, vinylon and viscose fibers. The sizing film is colorless and transparent, with strong toughness, wear resistance, sun resistance and high mechanical strength. It can reduce the breakage rate of the cloth machine. Due to the small sizing amount, the woven cloth feels neat, smooth and fine, and the cloth surface is not rough. It can also increase the number of winding pieces, and the desizing is easy.
PVA 2488 can also be used as a fabric finishing agent, often mixed with urea and formaldehyde. When the fabric is baked at high temperature, the chemical reaction between the two will occur, making the resin more flexible, thus improving the elasticity of the processed fabric.
