A.k.a. p-xylene, p-methyltoluene, 4-methyltoluene, 1,4-dimethylbenzene, or PX. A high volume chemical intermediate that is an isomer of xylene.  Primarily used as a raw material in the manufacture of terephthalic acid (TPA), purified terephthalic acid (PTA), and dimethyl-terephthalate (DMT) used to produce polyester. Chevron Phillips Chemical is one of the largest marketers of high purity paraxylene in the world. 

Chevron Phillips Chemical Performance Fuels meet many established industry and military specifications. The company also formulates fuels designed to meet API, EPA, CARB, IP, ISO, DIN, ECE, and other specifications.

A class of thermoset resins made by the condensation of phenol or phenol-containing compounds with aldehydes such as acetaldehyde or formaldehyde.

Compounds added to high molecular weight polymers to give them flexibility, softness, and stretch.  Plasticizers can be added mechanically at the compounding or shaping stage or chemically by co-polymerization.

A.k.a. PE. A versatile plastic derived from ethylene. Chevron Phillips Chemical is one of the largest PE producers in North America and the world. Our polyethylene lines include HDPE, LDPE, LLDPE, MDPE, enhanced polyethylenes and oxygen scavenging systems for applications such as food packaging, bag liners, geomembranes, high-pressure pipe, and fuel tanks. 

A large molecule formed by chemical reaction of one or more lower molecular weight reagents of five or more several identical combining units (monomers).

A chemical reaction, typically catalytic in nature in which monomers and possibly co-monomers are reacted to form a high molecular weight material.  It can occur spontaneously or by introduction of reactive substances.

A.k.a. PP. Found in everything from flexible and rigid packaging to fibers and large molded parts for automotive and consumer articles, polypropylene is a low-density plastic. Chevron Phillips Chemical produces and markets polypropylene through a partnership with Sumitomo Chemical Company Ltd., known as Phillips Sumika Polypropylene Company.

A.k.a. PS. A versatile plastic derived from styrene that can be produced as foam or rigid packaging. Chevron Phillips Chemical produces and markets general-purpose polystyrene for use in containers, lids, cups, and other applications.

Propylene is an olefin molecule of chemical formula C₃H₆ produced from natural gas liquids and refinery streams in steam crackers. Chevron Phillips Chemical uses propylene internally to manufacture polyethylene, polypropylene, alpha olefins, and styrene and sells it to external customers who produce these and other materials such as polyester, acrylics, ethylene glycol antifreeze, polyvinyl chloride (PVC), propylene oxide, oxo alcohols, and isopropanol. 

Purified terephthalic acid (TPA).

A chemical product characteristic measured as 100% minus the sum of impurities proscribed in a given specification.

A.k.a. pygas. A by-product of ethylene production used as a source for benzene.

A process in which high heat alone (i.e. without oxygen) is used to transform one compound into one or more lower molecular weight materials.
