Plastics colorations studies at DuPont's new Pigments Sales Service Laboratory, at Chestnut Run Laboratories. The panel the technician is working on is called draw-down. Pigment samples are cured in an oven, then tested for heat and light stability...
A technician in DuPont's new Polychemicals Sales Service Laboratory at Chestnut Run near Wilmington, Delaware checks blown film in tubular form made from Alathon polyethylene resin.
A technician at DuPont's pipe manufacturing plant at Tulsa, Oklahoma adjusts extrusion equipment as it produces endless footage of Delrin acetal resin pipe for ultimate use by the oil and gas industry. The two inch diameter light weight, corrosive...
Costly lab gadgets explore and test in contingent effort to build better quality into products. Here, a technician uses a radar like cathode ray oscillograph, the wavy light steaks measuring precisely the split second brining time of a blasting cap.
The balance is one of the basic research tools of the chemist and the starting point of virtually all analyses. This DuPont technician at the Experimental Station weighs a titanium salt for quantitative analysis.
Attractive Florence Naum, Ford Motor Companys only woman electrical technician, tests a generator regular quality control machine at the Ypsilanti MI plant. A resident of nearby Farmington, Miss Naum has been with the company for almost ten years....
Close up of south face of Brookhaven Reactor-Through these holes in the south face of the Brookhaven reactor are introduced tons of pure uranium metal. Once in the graphite moderator of the reactor proper, uranium atoms fission, or spilt, in a...
Nylon plastics stripping for furniture, now being produced by DuPont in experimental quantities is strong, durable, easy to clean and is expected to be available in a variety of colors. Here laboratory technician Ruth Eck orients a 2 inch wide...
This is one of three pictures that show why paper. Coated with Alathon polythene resin, can be used for packaging materials that are highly acidic or corrosive in nature. A laboratory technician at the DuPont Company's Experimental Station in...
The nation's bill for glass breakage in street lamp globes, ticket windows, washroom windows and other public installations, may be reduced by DuPont's development of patterned sheets of shatter resistant Lucite acrylic resins. Sections for office...
From a boiling bath of hot sulfuric acid, a laboratory technician lifts two rods of plastic. One has charred and deteriorated. The other-a rod of DuPont's new Teflon tetrafluoroethylene resin-is not affected at all by the highly corrosive hot acid....
A laboratory technician places a piece of Teflon tetrafluoroethylene resin, a DuPont industrial plastic, in an instrument which measures the plastic's dielectric constant and power factor at 3000 megacycles. Because its dielectric loss factor is...
A circular piece of Teflon tetrafluoroethylene resin, a DuPont industrial plastic, placed between tinfoil electrodes, is being measured for its dielectric constant and power factor at 60 to 15,000 cycles. A laboratory technician adjusts the...
From a boiling bath of hot sulfuric acid, a laboratory technician lifts two rods of plastic. One has charred and deteriorated. The other-a rod of DuPont's Teflon tetrafluoroethylene resin-is not affected at all by the highly corrosive hot acid....
A laboratory technician places a disc of Teflon tetrafluoroethylene resin, a DuPont industrial plastic, in a high voltage testing set to measure its dielectric strength. The transformer oil bath serves as an insulator to prevent voltage flash over...
A laboratory technician inspects a sheet of Viton fluoroelastomer. As shipped by DuPont from its plant at Deepwater Point, New Jersey, Viton is a translucent, light color gum. This new special purpose rubber is a result of DuPont's long activity in...
A technician removes combs made of Zytel nylon resins from a modern injection machine at the Plastic Department's Technical Services Laboratory. The DuPont laboratory is located at Chestnut Run.
Using a pantograph, this technician at the Plastics Department's Technical Services Laboratory is duplicating the profile of an intricate part in bar of Zytel nylon resin. Tests are made on such machined parts before injection molds are built. The...
