successes and spawning new applications at a remarkable rate, are fast becoming one of industry's most exciting developments. Their low cost, ease of application, and variety of forms (ranging from supple flexibility through semi-rigid to most rigid types) have tickled the imagination of thousands. Here are some developments to date:
Experience builds confidence
the widest range of desirable properties of any available industrial foam more accurate control of degrees of toughness, resilience, weight per unit volume, shock absorbency, insulating properties marked price advantages over polyester foams and foam rubber a solvent-blown rigid urethane foam which can be applied with readily available standard portable hotspray catalyst equipment But, as with all new developments, experience is an allimportant factor. It can prevent costly mistakes, fruitless evaluation, conserve priceless laboratory time, cut costs, and insure greater product satisfaction. So, if you have an interest in urethane foams — either flexible, semi-rigid, or rigid types — consider these facts: 1. Wyandotte pioneered in the development of the polyethers that have greatly improved urethane foams, given them a longer useful life, lowered their cost, and offered a far wider range of desirable properties. 2. Wyandotte was the first to develop a sprayable solventblown polyether rigid foam. 3. Wyandotte has extensive urethane application and development laboratories cooperating with all manufacturers of urethane foams, and with prepolymer manufacturers on the latest urethane-foam formulations. This valuable experience (and our facilities) are available to you if you make, wish to make, or use urethane foams as a part of your own products or processes. Just write us, describing your requirements in as much detail as possible. Wyandotte Chemicals Corporation, Wyandotte, Michigan. Offices in principal cities.
