Shares of Orion Engineered Carbons (OEC - Get Report) are deep in the black, up 37 percent year-to-date. And the company's CEO Jack Clem said he expects the good times to continue - and volumes to remain strong - in the second half of 2016 as well. 'We had spectacular performance from our specialities business in the second quarter and our rubber business saw substantial volume growth on the heels of our acquisition in China,' said Clem. 'As the economy improves, so should our volumes the rest of the year.' Last week, Orion reported its strongest results ever as a public company. The leading producer of specialty carbon black - used in coatings, polymers, and inks - and rubber carbon black - primarily used for tire manufacturing - reported second-quarter earnings of $18.6 million or $0.40 a share on sales of $280 million. Orion's results exceeded Wall Street expectations of $0.36 a share.
