TECHNICAL TERMS & ABBREVIATIONS Technical Terms & Abbreviations Acrylonitrile (AN) AN, an intermediate product, is used for many applications such as acrylic fiber, automotive parts, and electric appliance parts. Aromatics A group of cyclic hydrocarbons containing one or more benzene rings of six carbon atoms characterized by single and double bonds, such as benzene, toluene, and xylene. Bio-based Polybutylene Succinate (Bio-PBS) Bio-PBS, a natural material made from bio-succinic acid and 1,4-butanediol, used in applications such as paper coating, compound injection, and packaging. Bisphenol A (BPA) BPA, an intermediate product produced from acetone and phenol, is used to produce polycarbonate or epoxy resins. Butadiene Butadiene, derived from the extraction of mixed-C4, is used in making synthetic rubber. Butene-1 Butene-1, a byproduct of the cracking of petroleum (kerosene or gasoil) and naphtha distillation, or extraction of mixed-C4, is used as polymer feedstock. Carotenoid Carotenoid, a natural substance found in plants, vegetables, fruits, and microbes, consists of the carotene group and xantho group. Carotene, such as beta carotene and lycopene, is fats-soluble, whereas xantho, such as lutein and astaxanthin, is less fats-soluble. Crosslinkers (XLR) Crosslinkers are molecules that connect polymers chains at specific reactive sites, thereby enhancing the performance of coatings by increasing the chemical and scratch resistance. When paired with catalysts they can accelerate the reactivity of formulations. EO-Based Performance Product EO-based performance products refers to ethylene oxide derivatives such as ethylene oxide, ethylene glycol, ethanolamine products, and ethoxylate. Ethanolamine (EA) EA, obtained from the reaction between ethylene oxide and ammonia, is used in hair conditioner, fabric softener, cosmetics, and pharmaceuticals. Ethoxylate Ethoxylate, produced from ethylene oxide, is used as a surfactant in soap and detergent. Ethylene Ethylene, obtained from ethane, LPG, or naphtha, is feedstock for polyethylene, vinyl chloride monomer, styrene monomer, and ethylene oxide. Ethylene Glycol (EG) EG is synthesized from ethylene oxide reacting with water, producing mono ethylene glycol, diethylene glycol, triethylene glycol, and polyethylene glycol. Ethylene Oxide (EO) EO, obtained from the reaction between ethylene and oxygen, is a chemical intermediate of ethylene glycol, ethanolamine, and ethoxylate, and others. 346 PTT GLOBAL CHEMICAL PUBLIC COMPANY LIMITED Form 56-1 One Report 2021
