Carbomer polymer is a cross-linked polyacrylate polymer. It is an extremely efficient rheology modifier capable of providing high viscosity and forms sparkling clear water or hydroalcoholic gels and creams.Carbomer 940 polymer short flow (non-drip) properties are ideal for applications such as clear gels, hydroalcoholic gels, creams.
Product Description:
Carbomer 940 is an acrylic cross-linked resin obtained by cross-linking acrylic acid with pentaerythritol, etc. It is a very important kind of rheology modifier. After neutralization, carbomer is an excellent gel matrix, which is important for thickening and suspension. Uses, simple process, good stability, widely used in emulsions, creams, gels.
[Usage and precautions]
Carbomer 940 is a cross-linked acrylic polymer that swells with water and a small amount of neutralizer (such as neutralizer and neutralizer 2) is added to form a highly transparent gel. Different types of carbomer represent different viscosities. It is known as short rheology or long rheology, for example: Carbo 940 has short rheological properties, reaching 63000MPA.S at 0.5% viscosity, suitable for products with high viscosity, Carbo 941 has long rheological properties, at 0.5% Viscosity of 7500MPA.S is suitable for low-viscosity products. Carbomer's corresponding models have ion-resistant and ion-resistant performance, daily chemical industrial products.
