Technical Terms & Abbreviations Mono Ethylene Glycol (MEG) MEG is most commonly used as chemical intermediate in the manufacture of polyester resins and textile fibers. MEG is also wildly used as automotive antifreeze due to its low freezing point when mixed with water and used as heat transfer fluids for ventilation and air-conditioning systems. Naphtha Naphtha is separated from crude oil in the fractional distillation process. Naphtha refers to the light fraction produced by distillation that is roughly in the gasoline boiling range. It serves as petrochemical feedstock and as a solvent. Olefins Olefins are unsaturated hydrocarbons with at least one carbon-carbon bond. The main olefins include ethylene, propylene, and butadiene. Oleochemicals Oleochemicals are natural chemicals derived from plant fats and animal fats, such as fatty alcohols, methyl ester, and glycerin. O-xylene or Orthoxylene (OX) This aromatic compound with two methyl groups in the 1- and 2-positions of the benzene ring is used to produce phthalic anhydride, feedstock for plasticizers. Phenol Phenol is an intermediate-stream petrochemical product, which is created from Benzene and Propylene as feedstocks. It is used as an important substrate in the production of Bisphenol A (BPA) and Phenolic resin, plastic industry, agriculture industry, pharmaceutical manufacturing industry, etc. Polymers Chemicals with molecular weights of 5,000 or more, derived when certain individual monomers come together and link up. Examples are polyethylene, rubber, and cellulose. Polypropylene Polypropylene, a thermoplastic polymer derived from the reaction between propylene and catalysts, is used in containers, textiles, and injected plastics. Polyethylene Terephthalate (PET) PET is made by combining mono ethylene glycol and pure terephthalic acid. PET and mono ethylene glycol serve as feedstock for synthetic fiber, water bottles, audiotapes, adhesive tapes, film, food packaging, and others. Polyols Polyols is an intermediate petrochemical product, used as main feedstock to produce polyurethane. Polystyrene A thermoplastic made from styrene monomer. Polyurethane (PU) PU, a thermoplastic resulting from glycol and diisocyanate condensation, can be stiff, soft, or flexible, depending on the additives used. When blended with rubber, it provides shoe soles, heat insulators, windshield wipers, and others. Polyvinyl Chloride (PVC) PVC is a thermoplastic polymer produced from vinyl chloride monomers (VCM), and consists of unplasticized and plasticized PVC. It is used in water pipes, electric wire conduits, artificial leather, among others. Powder Coating Resins Powder coating resins are solids (not carried in water or solvent) which upon ovenbaking forms a protective film that provides superior durability and weathering resistance to the coated object. They are commonly used to coat metals in applications ranging from agricultural and construction equipment, and household electrical appliances. 360
