Texmark's primary businesses are dicyclopentadiene (DCPD), dicyclopentadiene alcohol, resin intermediates, n-butanol, specialty products made from DCPD or CPD (cyclopentadiene), and contract processing. Texmark is the second largest producer of DCPD in the U.S.

David Smith, President, summarizes his view of Texmark this way-"We compete on service. Our prices are competitive, and our quality is consistent and outstanding. Superior service gives us our competitive edge. Our customers know we will respond quickly and efficiently to routine requests and to emergencies. Time after time we have arranged transportation and shipped product within only a few hours of receiving a request. That's the Texmark difference."
