Conclusion

Diversification through competitive raw material: current feedstock profile with higher exposure based on

naphtha that presents higher costs and that could create exposure to carbon pricing mechanisms.

Acess to competitive feedstock

Raw Material Profile

Recent investments to diversify feedstock:

1. Braskem Idesa complex: 1,05kt PE production using 100% ethane as feedstock.

2. Feedstock flexibility project in Bahia: Braskem is investing R$ 380 million to enable the cracker in Bahia to use ethane for up to 15% of its feedstock. The project is scheduled to start operating in the second half of 2017.
