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. Fatty Alcohol Fatty alcohol, produced from methyl ester and hydrogen through hydrogenation, is used in personal care products. Glycerin Glycerin, a by-product of methyl ester production, is used in pharmaceuticals, food, and personal care products. Hexamethylene Diisocyanate (HDI) HDI, obtained from the reaction between hexamethylenediamine and phosgene, is used in polyurethane production. Hexene-1 Hexene-1, an organic compound primary is used as a comonomer in production of polyethylene. High Density Polyethylene (HDPE) HDPE produced from ethylene monomers, HDPE is a very dense and crystallized thermoplastic used for containers, including plastic bags, bottles, fuel containers, tanks, and cartons. Hydrocracking Hydrocracking is a process of breaking up hydrocarbon molecules by breaking up carbon-carbon bonds with the use of hydrogen and catalysts. Linear Low Density Polyethylene (LLDPE) LLDPE, properties are between LDPE and HDPE, but it is softer and more ductile than LDPE and HDPE have been processed into film, relatively clear, soft, stretchable. Product type is clear, strong and sealable products such as vegetable bags, fruit bags, bread bags, food bags. Low Density Polyethylene (LDPE) LDPE, the appearance is quite clear, soft, flexible and resistant to acidic and alkaline chemicals. Can be easily processed. It is electrically insulated and including able to support the impact well. It widely used in various types of plastic bags such as industrial bags, ice bags, frozen food bags. Methyl Ester Methyl ester, derived from the reaction between crude plant/vegetable oil or animal fats and alcohols under esterification, is used for biodiesel production. Methyl Methacrylate (MMA) MMA is an intermediate product for Poly Methyl Methacrylate (PMMA) used for LCD screen light guide panels, automotive parts, and billboards. Mixed C4 Mixed C4, the by-products produced from naphtha crackers for olefins production, can be isolated into butadiene, butane-1, and isobutene, and others. Mixed Xylenes Aromatics derived from naphtha undergoing a chemical reaction aided by catalysts. They consist of paraxylene, orthoxylene, and metaxylene, all capable of serving as reactants for higher-value aromatics and as industry solvents.
