11. Outlook and Priorities
Petrochemical Industry:
 Global industry scenario in 2H11 points to recovery in resin-naphtha spreads over 2Q11
 Scheduled stoppages in Asia and recovery in local demand;
 Continued instability in Middle East operations;
 Lower capacity utilization rates (U.S. and Europe).
 Risk Factors
 Slowdown in demand from emerging countries impacted by the crisis in developed economies;
 Volatility in raw material prices, driven by stronger speculation on oil prices.
Braskem’s priorities:
 Support the development of an industrial scenario that strengthens the Brazilian petrochemical and plastics
chain
 Recover market share, combating “subsidized” imports
 Ensure capture of identified synergies
 Integrate new PP plants located in U.S. and Germany
 Maintain liquidity and financial health
 Expansion Project
– Expansion of the new PVC Alagoas plant
– Final Investment Decision for the Ethylene XXI Project in Mexico, based on competitive feedstock
– Define Comperj configuration with Petrobras
– Study projects aimed at the access to competitive feedstock in U.S. (shale gas)
– Expand use of renewable feedstock
