Our specialty synthetic wax segment is conducted through Trecora Chemical, Inc., a Texas corporation, located in Pasadena, Texas which produces specialty polyethylene and poly alpha olefin waxes and provides custom processing services. The specialty polyethylene waxes are used in markets from paints and inks to adhesives, coatings, and PVC lubricants.

These waxes are sold in solid form as pastilles or, for large adhesive companies, in bulk liquid form.
