Baton Rouge specialty chemical maker Albemarle Corp. has completed an expansion at its Tyrone, Pa., custom manufacturing facility.

The expansion, which doubles the capacity for a proprietary chemical product manufactured for an Albemarle customer, began operation earlier in November and is now operating at full rates.

“Executing this multimillion-dollar expansion in less than one year allowed our customer to capitalize on the growing demand for its product, and the construction effort had no impact on fulfilling the production needs of our other customers,” said David DeCuir, director, fine chemistry services.
