Product Chemical Structure and Properties
1. Molecular Structure
HPMC is a nonionic water-soluble cellulose ether formed by partial replacement of the hydroxyl groups on the cellulose molecular chain by methyl (–CH₃) and hydroxypropyl (–CH₂CH(OH)CH₃).
2. Basic Physical Properties
Property Description
Appearance White or off-white powder
Solubility Soluble in cold water, insoluble in hot water and most organic solvents
pH value Usually 4.0~8.0 in 1% solution
Viscosity Wide range (from 5 mPa.s to more than 100000 mPa.s), depending on the model
Film-forming property Good transparency and toughness
Thermal gelling property Gel is formed after heating and restored to solution after cooling
Application Areas
Construction Industry
Tile adhesive: improve thixotropy, anti-slip properties, and enhance adhesion
Interior and exterior wall putty: improve water retention, prevent cracking, and enhance coating properties.
Self-leveling mortar: optimize fluidity and workable time, and improve surface quality.
Thermal insulation mortar: prevents cement shrinkage and cracking, and improves adhesion and water retention.
Spray plaster: improve lubricity and workability, prevent delamination and shedding
Pharmaceutical Industry
Tablet binder: improves particle forming rate and disintegration.
Controlled release film coating material: regulates the drug release rate.
Capsule shell material: suitable for vegetarian capsules, alternative to gelatin
Ophthalmic preparations: used for artificial tears, etc.
Daily chemical industry
Laundry detergent, dishwashing liquid: thickening, suspension, and anti-stratification.
Skin care products: moisturizing, film-forming, improving skin feel.
Toothpaste: Enhance the stability of the paste and prevent stratification.
Other Industries
In latex paint, HPMC acts as a thickener and stabilizer, which not only provides good workability but also enhances the uniformity and smoothness of the paint film.
Ceramic industry
Used in ceramic molding, enhancing the plasticity and bonding strength of the embryo, improving the drying and cracking problems, and improving the yield rate.
Pesticides and fertilizers
Used as suspending agents, adhesives and controlled-release membrane materials to disperse pesticides evenly, prevent precipitation and improve the use effect.
Superior performance and advantages of HPMC
1. Excellent water retention performance
In applications such as mortar and putty, it effectively prevents premature evaporation of water and improves construction quality.
2. Excellent thickening performance
It has a significant thickening effect even at low concentrations, making the product rheology more ideal.
3. Excellent film-forming property
HPMC can form transparent and flexible films, which are widely used in medicine, coatings, food and other fields.
4. Strong thermal stability and pH stability
It can be used stably in a wide pH range (3–11) and has unique thermal gel properties.
5. Safe, non-toxic and biodegradable
It meets green environmental protection requirements and is suitable for fields with extremely high environmental protection requirements, such as medicine, food, etc.
