Top selected global customers: Our Businesses The following is a discussion of our reportable segments  their corresponding major product lines and the primary end-use applications of our key products as of December 31  2020. We are the leading producer of formaldehyde-based resins for the North American forest products industry  and also are a leader in the following regions: Latin America  Australia and New Zealand. Formaldehyde-based resins  also known as forest products resins  are a key adhesive and binding ingredient used in the production of a wide variety of engineered lumber products  including medium-density fiberboard (“MDF”)  particleboard  oriented strand board (“OSB”) and various types of plywood and laminated veneer lumber (“LVL”). These products are used in a wide range of applications in the construction  remodeling and furniture industries. Nearly all of our formaldehyde requirements for the production of forest products resins are provided by internal production  giving us a competitive advantage versus our non-integrated competitors. In addition  we are a significant producer of formaldehyde  a key raw material used to manufacture thousands of other chemicals and products  including the manufacture of methylene diphenyl diisocyanate (“MDI”) and butanediol (“BDO”). Formaldehyde consuming products are used in multiple applications including agricultural  construction  energy and automotive industries. We are also a leading supplier of phenolic resin coated proppants used in oil field applications. Our highly specialized compounds and resins are designed to perform well under extreme conditions  such as intense heat  high-closure stress and corrosive environments  that characterize oil and gas drilling and are also used to enhance oil and gas recovery rates and extend well life. Both forest products resins and formaldehyde have relatively short shelf lives  and as such  our manufacturing facilities are strategically located in close proximity to our customers.
