By special request a brass end may be specified in place of the
acetal resin (POM) standard.
Nylon 66 and
acetal resins were extruded at various screw speeds.
The company also has LYCRA(R) spandex fiber, DELRIN(R)
acetal resin and adipic acid plants here.
Ground was broken at Shenzhen in April on two additional wholly owned facilities to manufacture "Delrin"
acetal resin and "Tynex" nylon monofilament.
Made of Du Pont Delrin 100
Acetal resin, the centering sphere has been in continuous use since 1963 on GM, AMC, Chrysler, Rolls Royce, and Jaguar cars.
A 77-member team at the DORDRECHT, NETHERLANDS, plant eliminated in six months all of the raw polymer waste generated from manufacture of "Delrin"
acetal resin, an engineering polymer used in automobiles, among other applications.
The Delrin
acetal resin plant in Dordrecht, The Netherlands, was certified to ISO 9000 quality standards in 1990, the third of Du Pont's plants in Europe to be so designated.
Manufacturers use formaldehyde to manufacture formaldehyde resins and other downstream products such as
acetal resins, BDO, MDI, and pentaerythritol.
World production of formaldehyde is about 15 million metric tons, and this gas is used mainly in the production of phenolic, urea, melamine, and
acetal resins, which have wide use in the production of adhesives and binders in the wood, plastics, textiles, leather, and related industries (20,42).
The DuPont Performance Polymers business manufactures and sells Crastin[R] PBT and Rynite[R] PET thermoplastic polyester resins, Delrin[R]
acetal resins, Hytrel[R] thermoplastic polyester elastomers, DuPont[TM] ETPV engineering thermoplastic vulcanizates, Minlon[R] mineral reinforced nylon resins, Neoprene polychloroprene, Tynex[R] filaments, Vespel[R] parts and shapes, Kalrez[R] perfluoroelastomer parts, Vamac[R] ethylene acrylic elastomers (AEM), Viton[R] fluoroelastomers, Viton[R] FreeFlow[TM] processing aids, Zytel[R] nylon resins and Zytel[R] HTN high-performance polyamides.
For the case of
acetal resins, a specific test to measure formaldehyde emission is available as VDA 275 from the German Association of the Automotive Industry.
a two-year-old compounder of engineering thermoplastics, has expanded its product range by becoming the North American distributor of Kocetal-brand
acetal resins produced by Kolon Chemical Co.
