2019-09-11 20:59:21

Carbomer product are cross-linked polyacrylate polymers, including polyacrylic acid homopolymer and acrylate copolymer.


They are polymerized by method of solvent polymerization -precipitation polymerization.

NM-Carbomer are defined as short flow type and long flow type by their viscosity.

For example, NM-Carbomer 940, 980, 676, 996 with 0.5% solution viscosity ~55,000maps, are short flow property.

and carbomer 941,981with 0.5 solution viscosity ~7,500mpas being long flow property.

NM-Carbomer are defined as traditional homopolymer and modified copolymer by monomers in synthesis.

For example, NM-carbomer 10, 940, 980,990, 941,981 are polyacrylic acid homopolymers and traditional carbomer products.

NM-carbomer 20,21,2020, are hydrophobically modified cross-linked acrylate copolymers,

providing good electrolyte tolerance and unique sensory benefits in formulations.
