Polypropylene’s lightweight, durability, and thermal resistance make it a preferred alternative to traditional materials such as metals in structural and packaging applications.
Beyond polypropylene, propylene is used in the production of acrylonitrile (for ABS plastics), propylene oxide (used in foams and coatings), and cumene (a precursor for phenol and acetone). Ongoing innovation and material substitution trends continue to drive the expansion of propylene-based products.
3. Aromatics: Benzene, Toluene, and Xylene (BTX)
Aromatic compounds, including benzene, toluene, and xylene (collectively referred to as BTX), are essential for producing a range of downstream products such as resins, nylon, and synthetic fibers. Benzene remains highly utilized for producing styrene and phenol, key ingredients in engineering plastics and adhesives. In March 2025, Lotte Chemical announced the startup of its USD 3.9 Billion Cilegon facility in Indonesia, which will manufacture key BTX products to support regional and global petrochemical demand.
Toluene is processed into toluene diisocyanate (TDI), used in flexible foams for furniture and automotive seating. Xylene, particularly para-xylene, is in demand for manufacturing purified terephthalic acid (PTA), a precursor to polyester and PET bottles. As transport fuels undergo decarbonization, producers are investing in integrated refining-petrochemical complexes to optimize BTX production.
4. Methanol and Its Derivatives
Methanol is gaining importance due to its role in producing formaldehyde, acetic acid, and MTBE, as well as in methanol-to-olefins (MTO) technologies. Additionally, methanol is being adopted as an alternative fuel source in marine, industrial, and transportation applications. Latin America and Southeast Asia are seeing significant investments in green methanol projects using biomass and carbon capture-based hydrogen. For example, in October 2024, HIF Global launched its first Brazilian project to produce 800,000 tons of e-methanol annually from green hydrogen, utilizing 1.6 GW of electrolyzers and captured CO2.
