Sichuan Chengdu carbomer powder 940-980 spot

  Overview Tc-carbomer 980 carbomer resin is a cross-linked acrylic polymer containing polyether polyols
It is a white loose powder with strong moisture absorption
Because its molecular structure contains carboxyl group, it has a certain degree of acidity and can be neutralized by basic substances to form transparent gel
After carbo resin is neutralized to ionize the carboxyl group, due to the mutual repulsion of negative charges, the molecular chain is dispersed and extended, in a greatly expanded state and viscous
Carbo resin can produce high thickening effect at very low dosage
Carbo resin can make the liquid system have special yield value and rheology
It only needs a very low concentration to make some insoluble additives (particles, oil droplets, etc
) permanently suspended
Because of its strong suspension ability, Carbomer resin is widely used to stabilize the traditional oil / water emulsion and cream, suspension droplet particles and water insoluble substances
The viscosity of carbomer 980 gel is positively correlated with the concentration
The higher the concentration, the higher the viscosity of the gel
Carbomer 980 gel is sensitive to electrolyte ions
The presence of electrolyte makes the viscosity of carbomer 980 gel drop sharply, and the two valence ion has greater influence than monovalent ion
The decrease in viscosity of carbomer gel is mainly due to the fact that it reduces the repulsive force of isoelectric charges on the main chain of polymer, thus reducing the actual effective concentration of carbomer in the system
nbsp; Performance ① it has the functions of high-efficiency thickening, suspension and stability ② Short flow ③ High transparency ④ The viscosity of carbo resin is not affected by temperature (5) local drug delivery system, crystal clear gel, water or alcohol solvent   Application field 1
