Case Studies

Case Study 1

For more than 50 years, one of our customers had been forced to manufacture its products by having the reactionary process completed at one facility, then shipped to another facility for blending then onto another facility for final packaging. They were shocked to find out that Seatex was able to do all of it in a single pass.

We were able to serve as a one stop shop for the customer, performing everything in-house, including packaging and shipping. This added significant value to the customer by streamlining the logistics and reducing the total cost of ownership of their products.

Case Study 2

One of our customers had created a new-to-the-world molecule and needed to take it from the lab scale to the railcar scale. After confirming in our lab that we could successfully recreate the molecule with our assets, we ran it through progressively larger blenders to ultimately produce 10,000 gallons at a time.

Package, Label, Store, and Ship Any Way You Need

Whether you need us to warehouse your chemicals or get them where they need to be quickly, Seatex comes through. Our Rosenberg facility is served by on-site, on-demand railcar service, and our Rosenberg, Pasadena, and El Campo locations are within easy reach of the Port of Houston.
