High weatherability plastic grade golden rutile titanium dioxide - DR-2589

DR-2589 is a high-weatherability rutile titanium dioxide pigment specially designed for plastic applications. The product retains the superior blue undertone, excellent color brightness, and superior hiding power of DR-2588. The special dense amorphous silica and alumina surface treatment of DR-2589 acts as a barrier to protect the titanium dioxide surface from reacting with polymers or additives. Its special organic surface treatment ensures excellent dispersibility, superior processing flow properties, and low hygroscopicity in plastics. New surface treatment technology improves the heat resistance, light resistance, and weather resistance of plastic products, protecting them from UV light and improving their mechanical and electrical properties.

Rutile titanium dioxide - DR-2588

DR-2588 is a rutile titanium dioxide pigment specially designed for plastic applications. It features a strong blue undertone, excellent color brightness, and superior hiding power. Its special surface treatment ensures extremely low moisture absorption, very low high-temperature volatiles, ultra-low oil absorption, and outstanding dispersibility and processing flow properties in plastics.

Rutile titanium dioxide - R-251

R-251 is a versatile rutile titanium dioxide pigment designed for applications in coatings, paints, plastics, etc. It features a bluish undertone, excellent dispersibility, superior hiding power, and high gloss. Excellent particle size control, surface treatment technology, and impurity control ensure the product's superior pigment performance and good performance in various application systems.

Ferrous sulfate

This light green inorganic substance, also known as green vitriol, exists as a heptahydrate, ferrous sulfate heptahydrate, at room temperature. It is easily soluble in water, slightly soluble in alcohol, and insoluble in ethanol.

Liquid polymeric ferric sulfate

Polyferric sulfate is a new type of high-efficiency iron-based inorganic polymeric flocculant. It is reddish-brown in appearance and has a polynuclear complex ion structure in its molecule, which can be rapidly mixed with water at any ratio. The solution contains various forms of iron complex ions, which can quickly exert the effects of charge neutralization and adsorption bridging. Because polyferric sulfate forms large flocculated iron blocks and particles with a fast sedimentation rate, and has a wide applicable pH range, it can be used at room temperature. It has high removal rates for COD, BOD, color, turbidity, phosphorus, and grease, and also has a good deodorizing effect. Polyferric sulfate is particularly effective in purifying low-temperature, high-turbidity water. Relevant national standard GB14591-2016.
