2. Acrylonitrile Butadiene
Styrene
• ABS is a polymer which is gained by
polymerizing styrene and acrylonitrile with presence of
polybeautadiene.
• The resultant long chain of polybutadien is crossed linked
with small chains of poly(styrene-co-acrylonitrile).
The nitrile groups from adjacent chains, being polar, attract
each other and bind the chains together, making ABS
stronger than pure polystyrene.

3. Monomers in ABS
Chemical Formula:
(C8H8·C4H6·C3H3N)n

4. Tg= 105
M.P= no sharp melting point
• Useful temp range = 20-80
• Available form= garanular
• Tensile strenght= 74mpa
• Procesing = emulsion prosses
• S.G= 1.06
• Producers= BS eco international

8. Research Article: (World Cons. Of ABS)
Published November 2014
World consumption of ABS resins is led by appliances and
electronic/electrical applications, accounting for approximately
64% of total world ABS resin consumption. The next-largest
end use for ABS resins is in the transportation sector
(automobiles).
The largest consuming regions in 2014 were China (55%),
North America (9%), Western Europe (8%) and Southeast Asia
(7%). World consumption of ABS in 2019 is expected to
represent an average annual growth rate of 3.7%.
The ABS resin market is oversupplied, and no capacity
additions are expected in the next five years. Increasing demand
will absorb the excess capacity and is expected to foster
increases in overall operating rates from 2014 to 2019.
