PET - short version

Meaning 1:

Polyethylene terephthalate.

Meaning 2:

Powertrain/Engine/Transmission

Meaning 3:

Product Education & Training

Meaning 4:

Product Evaluation Team.

Meaning 5:

Product, Education and Training Committee. The PET Committee consists of the five Marketing Divisions (includes the Dealer Business Center) (voting members), Allied Divisions (i.e. GM of Canada, Delphi Automotive Systems, Delco Electronics, GM Powertrain, AC Delco-SPO), TCO, STD, and other GM groups with an interest in knowing about or influencing technician training (i.e. STG Product Engineering, STG International Service). The committee is chaired by the STD Manager. The PET Committee provides a single source of service training plans for General Motors. All groups with a service training message to convey to Dealers should notify the Committee. In this way, economies of scale are realized and redundant efforts minimized.

Meaning 6:

Program Evaluation Team.

Meaning 7:

Program Execution Team. Responsibilities are to: develop "Contract", act as a single point of entry for assessing all program content and change requests, balance new product and process feature content to meet "Contract" (cost, quality, and productivity), resolve program content issues, keep program imperatives on track, prepare gate reviews, provide program readiness coordination, achieve "Contract", monitor customer satisfaction, use common processes. Deliverables are: the "Contract", documentation for action items and content decisions, recommendations to VLT-problem resolution recommendation and mechanics. Typical attendees include: Program Planning Manager/Asst. VLE (Chair), Program Manager (Agenda/Logistics), Finance, Vehicle Integration Engineer, Manufacturing Integration Engineer, Purchasing/PC&L, Quality, Manufacturing, Assistant Brand Managers - Product, International Product Development Manager, Design Center (As Required). Typical meeting content involves: vehicle and process integration review issues, monitor program progress through rigorous tracking, performance to "Contract", content changes.

Meaning 8:

Program Executive Team.



PET - long version

Meaning 1:

Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P), is a thermoplastic polymer resin of the polyester family and is used in synthetic fibers; beverage, food and other liquid containers; thermoforming applications; and engineering resins often in combination with glass fiber.

Depending on its processing and thermal history, polyethylene terephthalate may exist both as an amorphous (transparent) and as a semi-crystalline material. The semi crystalline material might appear transparent (spherulites < 500 nm) or opaque and white (spherulites up to a size of some µm) depending on its crystal structure and spherulite size. Its monomer (bis-ß-hydroxyterephthalate) can be synthesized by the esterification reaction between terephthalic acid and ethylene glycol with water as a byproduct, or by transesterification reaction between ethylene glycol and dimethyl terephthalate with methanol as a byproduct. Polymerization is through a polycondensation reaction of the monomers (done immediately after esterification/transesterification) with ethylene glycol as the byproduct (the ethylene glycol is directly recycled in production).

The majority of the world's PET production is for synthetic fibers (in excess of 60%) with bottle production accounting for around 30% of global demand. In discussing textile applications, PET is generally referred to as simply "polyester" while "PET" is used most often to refer to packaging applications.

Some of the trade names of PET products are Dacron, Diolen, Tergal, Terylene, and Trevira fibers, Cleartuf, Eastman PET and Polyclear bottle resins, Hostaphan, Melinex, and Mylar films, and Arnite, Ertalyte, Impet, Rynite and Valox injection molding resins. The polyester industry makes up about 18% of world polymer production and is third after polyethylene (PE) and polypropylene (PP).
