Once thought purely a decorative facing, fir plywood now competes successfully with o t h e r materials in t h e rugged, high-stress construction field. The great strength these plywood sheets acquire t h r o u g h lamination is protected by Dowicide® 7. This preservative (PENTAchlorophenol) effectively inhibits t h e growth a n d action of bacteria a n d fungi, which could destroy t h e glue line and cause the plies to separate. Builders of modern Tacoma school economically used fir plywood sheets first as concrete forms, then as roof decking.

Dowicide Preservatives serve as bactericides, fungicides and germicides in most of t h e businesses that come to your mind. Fourteen different Dowicides increase manufacturing efficiency or stabilize product quality for paint, textile, petroleum, pulp a n d paper, agricult u r a l , transportation, leather, floor wax, cordage and m a n y other concerns. Your processing, packaging or selling might well benefit through use of o n e o r several Dowâcide Preservatives . . . they're all marked by high stability, ease of handling and proved effectiveness. Consultation with Dow's laboratories o n individual preservative problems is immediately available. For detailed information, mail coupon to THE DOW CHEMICAL COMPANY, Midland, Michigan.

. smaller, more reliable transformers made possible with Du P o n t M Y L A R *
CHALLENGING to industry . . . the almost unlimited opportunities for practical application of t h i s versatile new film Transformer Engineers, Pasadena, California, use D u Pont "Mylar" polyester film in transformer units for three different radars and two different guided missiles. T h e company reports that ''Mylar," in combination with epoxy resin, h a s helped save as much as 25 % in weight and volume—also helps give their transformers longer life. Industry everywhere is finding t h a t "Mylar," the strongest of all plastic films, permits a wide range of new and improved products comparable to these revolutionary transformers. A tensile strength of 23,500 p. s. i. permits its manufacture in gauges as thin as M of a mil (0.00025 inch).
And "Mylar" has a dielectric strength of 4000 volts/mil, is inert t o the attack of many solvents and insensitive to moisture. Excellent thermal stability of this n e w film through a wide temperature range is a n added plus. In a variety of fields, ranging from electrical capacitors to metallized fabrics, versatile D u Pont "Mylar"
is making possible better products . . . lower costs. With just a little reseax*Cu. âuu imagina Lion, you may be able to profitably link "Mylar" t o your product. Mail t h e coupon for your free copy of a booklet t h a t tells you more about "Mylar" and the ways it may help you develop or improve a product.
