TEXTURECEL™ 40000 PA is a high-purity sodium carboxymethyl cellulose powder used as a binder and an additive in coating, adhesive, and ceramic applications.
TEXTURECEL™ 40000 PA is a high molecular weight sodium carboxymethyl cellulose (CMC) polymer. It is a highly pure cellulose ether powder well suited as a binder in sensitive applications. When added to water at 1%, it will produce a solution with 4,000–5,000 cPs viscosity. When used in ceramic slurries, TEXTURECEL™ 40000 PA improves the green strength of ceramic parts prior to firing. It also works as a lubricant during extrusion and lowers the stress on extrusion equipment. TEXTURECEL™ 40000 PA is also an ideal additive for thickening and shear-thinning rheology for water-based coating and adhesive applications. In addition, TEXTURECEL™ 40000 PA is an excellent binder in anodes for lithium-ion batteries, where it increases mechanical integrity, improves adhesion to current collectors, and optimizes the dispersion of active material.
Viscosity (Brookfield, LVT, SP.3, 30 RPM, 0.5% dry basis aqueous solution, 25°C): 4,000–5,000 cPs
Degree of substitution: 0.82–0.95
pH value (1% aqueous solution): 6.5–8.5

Primary Chemistry: Sodium carboxymethylcellulose
Anionic
Water soluble at any temperature
High surface tension, forms less foam
Excellent viscosifier
Facilitates reversible viscosity decrease upon heating
Stable in a wide pH range from 3.5 to 12
Compatible with nearly all other hydrocolloids
No odor and no taste
Forms films resistant to fats, oils, and organic solvents
Poor battery life caused by impurities in the anode binder material
Incompatibility with other hydrocolloid thickeners
Deformation of water-based adhesives and coatings when applied to overhead and vertical surfaces
Use of rheology modifiers and thickeners that are not based on renewable resources like cellulose
