Butadiene, a colourless gas
Is a non-corrosive, flammable, colourless gas smelling faintly of petrol, obtained from the C4 fraction in the cracking process of naphtha. It is slightly soluble in water, as well as in methanol and ethanol and soluble in the commoner organic solvents, such as acetone, ether, benzene and cyclohexane.
The main applications of butadiene are synthetic rubber (SBR, SBS, thermoplastic rubber, etc.), widely used in producing shoe soles, tyres and other parts for the car industry, adhesives and sealants, asphalt and polymer modification and compounds for endless purposes.
It is also the basis for nylon and ABS resins, car tyres, electrical appliance shells and telephones, among others.
