The use of gaseous silica light transmittance, small particle size, can make the plastic become more dense, in the polystyrene

plastic film after the addition of silica, not only improve its transparency, strength, toughness, and waterproof performance and anti-aging properties are also significantly improved. The hardness, finish and anti-aging properties of plastic steel doors and Windows produced by adding a small amount of vapor-phase silica to the common plastic polyvinyl chloride are greatly improved.

Vapor silica is a kind of multi-functional additive, widely used in polymer composites, silicone rubber, coatings, electronic packaging materials, ceramics, plastics, glass steel, sealant, papermaking, food, cosmetics, chemical mechanical polishing and other industries, can play the role of reinforcing, thickening, thixotropic, extinction and so on, it is a real industrial nanomaterials in the world.
