coal tar

Superiority:

Black sticky liquid , Sample is available 

we have high temperature coal tar  ,middle temperature coal tar,low temperature coal tar 

Product Description 
Coal Tar is a kind of black sticky liquid, and getting from carbon which is being destructive distillation through Cutting-off air and enhancing thermal, meantime. Through high temperature carbonization can get  high temperature coal tar, on the contrary, it can get low temperature coal tar by low temperature carbonization. We provide high temperature coal tar. 

Physichochemical Property 
Coal tar has special distinctive odour. Its relative density  is 1.17~1.21 and the open flash point is at 200, and slightly dissolvie in water and Soluble in organic solvent, such as benzene,alcohol, aether, chloroform, acetone etc... Its fume and air can become explosion mixture , meanwhile, if meeting clear fire, high hot  that will have a combustion explosion danger , reacting violently with oxidizer.

Applications : 

Coal tar is a brown or black liquid of extremely high viscosity. Coal tar is among the by-products when coal is carbonized to make coke or gasified to make coal gas.  It is incorporated into some parking-lot sealcoat products, used to protect and beautify the underlying pavement. It is sometimes used for heating or to fire boilers, etc  .
