`
`Guidelines for Customer Use—All other customers
`
`All other customer usage is limited to a product signature arrangement, using Times Roman typog-
`raphy, that allows mention of DuPont products that serve as ingredients in the customer’s products.
`In this signature, the phrase, "Only by DuPont" follows the product name.

`
`A registration notice ® or an asterisk referencing the registration is required. In text, “Only by
`DuPont” may follow the product name on the same line, separated by two letter-spaces (see above
`example). When a DuPont product name is used in text, 6 ® or a reference by use of an asterisk must
`follow the product name. For example, "This device is made of quality DuPont Rynite® PET polyester
`elastomer for durability and corrosion resistance."

`

`General Description
`Rynite® PET thermoplastic polyester resins contain
`uniformly dispersed glass fibers or mineral/glass
`fiber combinations in polyethylene terephthalate
`(PET) resin that has been specially formulated for
`rapid crystallization during the injection molding
`process. Rynite® PET thermoplastic polyester
`resins are among the strongest and stiffest engi-
`neering resins available. As an engineering poly-
`mer resin family, Rynite® PET thermoplastic
`polyester resins offer a unique combination of
`properties—high strength, stiffness, excellent
`dimensional stability, outstanding chemical and
`heat resistance, and good electrical properties.
`
`Specific grades of Rynite® PET thermoplastic
`polyester resin are formulated with special empha-
`sis on strength, low warp and dimensional stability,
`toughness, high-temperature color stability, electri-
`cal properties, and excellent UL flammability and
`relative temperature index ratings.
`
`Rynite® PET thermoplastic polyester resins are
`noted for their excellent flow characteristics in thin
`
`wall applications, close molding tolerances, and
`high productivity from multicavity molds. Several
`compositions are exceptional in encapsulation
`applications. The properties, processing characteris-
`tics, and competitive price of Rynite® PET thermo-
`plastic polyester resins lead to high value-in-use
`and lower part cost and weight as compared to
`metals such as zinc or aluminum.
`
`Among the many successful applications for
`Rynite® PET thermoplastic polyester resins are
`housings and covers, support brackets, pump parts,
`electrical sensor housings, motor parts, lamp
`sockets, terminal blocks, switches, bobbins, oven
`handles and control panels, small appliance hous-
`ings, automotive support brackets, exterior compo—
`nents, headlamp retainers, ignition components, and
`luggage racks.

`Tensile Strength
`Rynite® PET thermoplastic polyester resins exhibit
`high tensile strength over a wide temperature range.
`Stress-strain data for various Rynite® PET thermo-
`plastic polyester resins at temperatures from —40 to
`150°C (—40 to 300°F) are shown in Figures 1
`through 15. For all Rynite® PET thermoplastic
`
`polyester resins, the pull rate for tensile testing is
`5 mm (0.2 in)/min. Before testing, sample bars are
`conditioned for a minimum of 40 hr at 23°C (73°F)
`and 50% RH. Conditioning reduces the tensile
`strength by about 5% from the values obtained on
`bars tested without conditioning.

`Flexural Creep
`Deformation under load with time is called creep.
`The amount of creep depends on composition (type
`of plastic, fillers, etc.), time, temperature, the
`applied stress level, and molding conditions. For
`Rynite® PET thermoplastic polyester resins, creep
`is decreased as crystallinity of the sample increases.
`Maximum resin crystallinity in a part is achieved
`by using a hot (293 °C [200°F]) mold. The creep
`characteristics of Rynite® PET thermoplastic
`polyester resins molded in hot molds (293°C
`[200°F]) are shown in Figures 21 through 50.
`These data, determined according to ASTM D2990,
`indicate that Rynite® PET thermoplastic polyester
`resins have good resistance to creep at high tem-
`peratures and stress levels.
