Beginning of α foam run in Jefferson's expanded U ret ha ne R&D Laboratories.

Reproducibility (or, in urethane language: one knotty problem) Time to start a new batch of foam. That's when urethane producers sweat. Can they get good reproducible foam with a few simple adjustments of the feed streams or will it require complex experimentation costing thousands of dollars in time and product?

counts to the urethane producer . . . then tests and more tests. From each production run of poly­ ethers, foam samples are made. Some 42 tests and measurements are made on these polyethers and foams to be sure they meet your requirements.

Of course there's no single answer. But the variables can be greatly minimized by using poly­ ethers and catalysts that are predictable performers run after run. Jefferson has achieved this con­ sistency through diligent attention to our proc­ essing and an intimate knowledge of what really

From super-softs to rigids, very likely our urethane technologists have the right answers for you. You get a great deal more from Jefferson than just excellent polyethers and catalysts . . . Jefferson Chemical Company, Inc., 1121 Walker Avenue, P. O. Box 303, Houston 1, Texas.
