We also produce a number of other specialty petrochemicals products, including metaxylene. We care about how we deliver these essential products to the world. Above everything, the safety, reliability and excellence in our operations is fundamental to our success. Our progress comes from the energy of our people, a team committed to continuous improvement and excellence.
