T o t h e b u y e r o f c h e m i c a l s the phrase " D o w is basic" means assurance of highest quality that can result only from complete control of all the building blocks t h a t go into a polyol formulation. It means assurance of uninterrupted supply, because the manufacturer is an original source— completely independent of raw mate rial problems. It means stable prices because ingredient costs are not sub ject to wide market fluctuations. And, in t h e r e a l m of creative chemistry it means t h a t t h e r e are literally no ma terial limits to t h e range of polyol possibilities and improvements t h a t are o p e n to D o w and its customers.
