PerformanceWhite powder, relative density4.0-4.6, insoluble in water, acid, alkali and other solvents,but soluble instrong acid and concentratedsulfuric acid. Heat resistance, acid resistance, alkali resistance, non-toxic can be used in contact with food products.

 

UseSupplementary filler, also used in plastics, rubber and other industries.

 

Advantages:YLFTActive barium sulfate (plastic special): is specially designedA product specially made in the plastics industry,High whiteness,Good stabilityIn the plastic production process,Has a good dispersion, can enhance the plasticStrongDegreeandHardness, maintain the surface gloss and brightness of the plastic,At the same time can also improve the productStiffness, viscosity,toughness and wear resistance.in high lightPP、PEAnd so on all kinds of high-grade plastic effect is very good. is a kindEnvironmental protection materials that can absorb harmful rays.Can replace part of the precipitated barium sulfate, titanium dioxide, active silica and other high-priced raw materials,Reduce costs.

 

Scope of application:Ultra-fine modified barium sulfate is widely used in various coatings, plastics, rubber, paint, ink and other industries. Can be used for acid-resistant rubber products and general products. Can also be used as a surface coating agent, sizing agent, weighting agent, also used in papermaking, ceramics, batteries, enamel, cosmetics and other fields. Articles that can be used in contact with food.
