German hydrophobic gas-phase white carbon black H20 fumed silica white carbon black Walker nano gas silicon
Model: R974
Product features : improve fluidity, enhance the lipophilicity and thixotropy of the system
Packaging specification : 10kg/bag
Applications : pharmaceuticals, cosmetics, toothpaste, adhesives, resin coatings, paints, inks, plastics, etc
White carbon black R974 is a hydrophobic gas-phase silica based on hydrophilic gas with a specific surface area of 130M2/g, which is processed by DDS (dimethyl dichlorosilane).
Application areas of white carbon black R974:
Ink (copier toner), paint, plastic, toothpaste, food, pharmacy, cosmetics, silicone rubber, sealant, adhesive, gel battery, composite materials, industrial lubricants, unsaturated polyester resin, layered resin and gel coat, cable insulation adhesive and cable gel, thickener of synthetic grease, plant protection and other fields.
Characteristics of white carbon black R974:
The main component is silicon dioxide, with a molecular formula of SiO2. It is a white fluffy powder, porous, non-toxic, odorless, and pollution-free, and resistant to high temperatures.
At the same time, the chemical inertness and special thixotropic properties of white carbon black R974 significantly improve the tensile strength, tear resistance, and wear resistance of rubber products. After rubber modification, the strength is increased by tens of times.
Control of rheological and thixotropic properties of liquid systems, adhesives, polymers, etc. Used as an additive for anti settling, thickening, and anti sagging.
White carbon black R974 can be used to regulate free flow and as an anti caking agent to improve powder properties.
White carbon black R974 can be used for waterproofing and hydrophobicity in liquid systems; Rheological control of complex liquid systems; Used for anti settling of coatings to improve pigment stability and strengthen corrosion protection; Improve the hydrophobicity and rheological properties of offset printing ink; Promote and maintain the flow and anti caking of the powder.
