How to squeeze 6-hours and 24-minutes into a 2-hour and 8-minute reel. For longer stretches of sound, it's the new skinny recording tapes. Super-thin, they let you put up to 3600 feet on a standard 7-inch reel. Twice—even three times— the playing time you used to get. And all on a normal tape machine!
Many of the best of the new skinny tapes are based on polyester formulas using DMT (Dimethyl Terephthalate) or TA (Terephthalic Acid) from Amoco. They're strong. More resilient. (Skinny tapes absorb tension by stretching.) And they're resistant to temperature and humidity extremes. They won't get brittle with age. Break. Curl up. Or warp.
Amoco Chemicals supplies both DMT and TA to polyester manufacturers serving the recording industry. The fabric, tire and surface coating industries, too. And we're still the only company that can!
It's a good idea to see us first when you're developing and testing polyester formulas for new products. DMT and TA from Amoco could help you do the job better. Amoco Chemicals Corporation, Department 9660, 130 East Randolph Drive, Chicago, Illinois 60601.
