Hot Melt Adhesive (Glue)
Fumed Silica series ( A 200)
Cas: 7631-86-9
Property:Fumed silica is artificial synthetic amorphous white powder flowability, surface area and volume of a variety of strict particle size distributions were different. It is a white, loose, amorphous, non-toxic, tasteless, odorless, non-polluting nonmetallic oxides.
Primary particle size ranging between 7 ~ 80nm, specific surface area is generally greater than 100m2 / g
Application: Due to its nano-effects in the material exhibits excellent reinforcing, thickening, thixotropic, insulation, matting, anti-sagging properties, which are widely used in rubber, plastics, coatings,painting, adhesives, sealants and other polymer industries fields.Dispersing agents in powder system, control agent in liquid system.
A-200: used widely in sealing ring, sealing gasket, petroleum pipeline, insulator, tablet powdered preparation, artificial viscera, infusion tube, latex nipple and high quality oil ink.
Specification:
Packing :
Multilayer moisture proof brown paper bag packing ,each bag 10 kg
