China Overseas Science & Trade Co.,Ltd

We are offering refined naphthalene. Refined naphthalene is the most important condensed-nuclei aromatics in industry. Its molecular formula is c10h8, white crystal, it is usually produced by the secondary purification of crude naphthalene it is the main raw material of producing 1-naphthol, 2-naphthol and other dye intermediate, plasticizer, synthetic resin，surfactant and so on.

We are offering coal tar pitch. coal tar pitch is a kind of black brittleness and blocky piece, lustrously at normal temperature. It has special odour and poisonous and can be easily flame when melting, second-grade inflammable solid. coal tar pitch is obtained from powerfully processed coal tar. Compared to petroleum asphalt, the adhesiveness is better. Coal tar pitch is high quality tar production with high fixed carbon. It has excellent adhesion, waterproofing and resistance against seawater, oil and various chemicals. In these properties, it is much better than petroleum asphalt tar

We are offering anatase titanium dioxide. Mainly used in producing plastics, decorative material, powder coating and industrial coatings, such as paint, rubber, papermaking, emulsion paint, ect

We are offering unf-5a naphthalene. Unf-5a naphthalene pure highly effective retarding & water-reducing admixture have the characteristics of retarding, super-plasticized, water-reducing, less loss of slump and high initial & ultimate strength. It is one kind effective concrete admixture to adopt in all kinds of climate engineering projects, and also specially suit for high temperature area

We are offering pc-6a polycarboxylic. It improves initial and ultimate strength. It also improves superior compression performance and workability of the concrete more than traditional water reducing mixture. It makes cement reduce water 25-40%

We are offering coal tar. By fractionation, it can get dutrex, alkane, phenols and also can produce asphalt felt, fuel and carbon black from coal tar. Coal tar can be used in electricity generation, coking coal for steel manufacturing and industrial process heating and medicated shampoo, soap and as a treatment for dandruff.

We are offering 2-naphthol. It is used in dye, rubber and oil paint, and the raw material of rubber antioxidant, bactericide, mold inhibitor, preservative

We are offering crude naphthalene. Crude naphthalene is the most important condensed-nuclei aromatics in industry. Its molecular formula is c10h8, which is the coal tar's most abundant constituent, and usually it is produced by recycling from distilling coal tar and coke-oven gas.it is the main raw material of producing phthalic anhydride, dye, resin, α-naphthoic acid, saccharine and water-reducing admixture etc.

We are offering modified asphalt. Modification coal tar pitch is the residue from coal tar oil that is separated by distillation extraction of light oil, carbolic oil, phenol oil, naphthalene, anthracene. Using a tube furnace continuous distillation, it is black solid under normal temperature. It is no fixed melting point, and heat softening and melting, density is .25～1.35g/cm3, it is a kind of heterocyclic compound contains oxygen, nitrogen, sulfur elements, etc
