Sodium carboxy methyl cellulose (CMC) is a non-toxic and odorless white flocculent powder with stable performance and easily soluble in water. Its aqueous solution is a neutral or alkaline transparent viscous liquid, soluble in other water-soluble glues and resins, but insoluble In organic solvents such as ethanol. CMC can be used as a binder, thickener, suspending agent, emulsifier, dispersant, …
PVA fine powder are specially designed for cement additives and contruction industry. They improve plaster properties such as flexibility, water retention, and increase plaster viscosity as well. In addition, they do not only reduce the friction of plaster but also enhance its working capacity and quality (Prevent cracking and shedding of plaster, increase adhesion and …
Hydroxyethy Cellulose (HEC) is a non-ionic cellulose ether. It is easily dispersed and dissolved in water to produce solution of high viscosity. HEC is used as a viscosity and rheology modifier, protective colloid, water retention agent, stabilizer and suspending agent, particularly in those applications where a non-ionic material is desired. The product has higher and …
Cellulose Ether for cement & gypsum based systems Methyl Hydroxy Ethyl Cellulose (MHEC/HEMC) widely used in building materials. Could be soluble in water to form a transparent solution. It can be widely used in masonry mortar, economic tile adhesive and inorganic thermal insulation mortar. Application & Advantage It is compatible with all conventional mineral …
Polyanionic cellulose, abbreviated as PAC, is a high-quality water-soluble cellulose derivative. This product is a white or light yellow free-flowing powder that is odorless, tasteless, non-toxic, and non-fermentable. It exhibits excellent thermal stability and high salt resistance. Polyanionic cellulose readily dissolves in water to form a viscous solution, and it is used to increase the …
In 2024, China’s PVA exports of 212,000 tons, an increase of 15.2%, becoming the highest level in history. Based on the price advantage of domestic PVA, the export orders of some main devices at the supply end of PVA are abundant, the atmosphere of export negotiation is good, and the export volume remains high. China’s …

PVA resin is a kind of heavy polymer. It is white or light yellow cotton-like, Granular or powdery in appearance. Its molecular formula is［CH2CHOH］n，and the molecular formula for some of the PVA is -［CH2CHOH］n-［CH2CHOOCCH3］m-. PVA is non-toxic, insipid and harmless. PVA is water-soluble and the solvent provide good viscosity and film building. It can …
PVA can be made from large particles into fine powder with different grade particle sizes by cryogenically crushing process, which can greatly accelerate the dissolution rate of PVA. For partial alcoholysis PVA powder, it can also be quickly dissolved in cold water. Application Widely used in various dry powder rubber powder, dry powder …

In the area of textile, PVA is primarily used as raw material of vinylon fiber and warp sizingagent. When PVA is used as raw material of vinylon fiber, it imparts the fiber with properties such aswhiteness, high strength, excellent hygroscopicity, and superior resistance to abrasion, sunlightand corrosion. Meanwhile PVA fiber can be spun in pure …
