What's the HEC Hydroxyethylcellulose ?
HEC Hydroxyethylcellulose - Properties
This HEC-PTMA is white or off-white or yellowish white powder or particle.
This HEC-PTMA forms colloidal solution in hot water or cold water, and is almost insoluble in acetone, ethanol or toluene.
How to test viscosity of hec?
Take 1% of the water solution of the product, use the rotary viscometer, and the No. 2 rotor rotates 12 revolutions per minute at 25 ° C The viscosity shall be 50%~150% of the marked value when measured according to the law at 1 ° C (the third method of general rule 0633) or according to the marked solution concentration and conditions.
HEC-PTMA Hydroxyethylcellulose - Introduction
HEC-PTMA is easily soluble in cold water and hot water, and the pH of the aqueous solution is 6.5-8.5. Insoluble in organic solvents. Thermal stability.
HEC Hydroxyethylcellulose - Application
PTMA-HEC is mainly used as emulsion stabilizer for lotion polymerization such as surfactant, colloid protector, vinyl chloride, vinyl acetate, etc., as well as viscosity increaser, dispersant, dispersion stabilizer, etc. of latex.
HEC can also be used as sizing agent in textile industry, adhesive, thickening, emulsifying, stabilizing and other additives in electronic and light industry sectors, and oilfield water-based gel fracturing fluid in petroleum industry.
