i s the problem solver.
Take cast urethane elastomers. And get the exact resilience/toughness combination you're after with Witco Formrez® prepoly mers. How so? Witco blankets the durometer range: Choose a single prepolymer that offers a very wide range of hardness, or individual grades that pro vide optimum physicals at any one hardness. Grades that give you resilience/tough ness that neither rubber nor plastics can without sacrificing durability—cut, tear,
abrasion resistance. Grades for continu ous or batch processing . . . for every thing from bushings and bearings to industrial rolls and tires. But maybe you have a special per formance or processing problem. Talk to our Organic Division's urethane ex perts. They'll help develop and deliver the best combination of durability and physical properties within your specific parameters. Prefer to make your own prepolymers? Witco can supply almost any hydroxyl-terminated linear polyester
you want. Custom-made, if not from our broad line available from stock. (Includes polyesters for one-shot production.) Producer or designer, you'll find Witco's flexibility of manufacture, ex acting control, and experience in ure thane technology will help you do that quality engineering job. Let us in on the problem (in confi dence). What's one more to the problem solver, but another one to grow on. Write: Witco Chemical, Organics Di vision, Dept. S-12, 277 Park Ave., New York, Ν.
