Heartland’s Agnieszka Lis, Lab Supervisor, shares how our state-of-the-art laboratory provides quality assurance for a consistent product

Leading processes, modern technology and operations expertise set the stage for developing a superior resin. Ensuring delivery of a high-performance product also requires a thorough analysis to confirm the quality remains consistent from the plant to the railcar.

So how do we assure a top-quality product from our facility to your production line? Cue our state-of-the-art laboratory building and team of technical experts.

Quality assurance from the lab

Our Heartland Petrochemical Complex’s onsite laboratory building is a critical feature of our quality control program. Our laboratory was designed and optimized to ensure that every aspect of production meets or exceeds the high standards of our supply chain partners and polypropylene customers. Extensive quality control testing takes place in our laboratory round-the-clock and includes examining the mechanical, physical and chemical testing of our polypropylene – qualities that can impact run rates and output for manufacturers down the line.

“The analysis we conduct in the laboratory building is very detailed and provides the highest level of accuracy. It is the assurance that we give to our customers that our product is of the highest quality.”
