Re:    Polymer Research

 This product is an exciting new addition to the CDS family! It is a very versatile and useful new polymer recently developed in our labs and I would like to introduce it to you personally!

            This product has been in the making for about 1 year now, and ever since we began production on the prototype handed to us engineers, we knew we had something special on our hands. The copolymer alone was spectacular: it was easily molded during creation, it didn’t stick to itself after creation, and it was remarkably strong for its size and shape!

            The list of useful properties of this polymer goes on: It is a naturally white polymer with a tendency to hold its shape, and didn’t absorb water very well. It dried out over an extended period of time, and with significant heating and also retained this heat long after the source of the heat was removed. It was a fairly bouncy product, and but did not stretch very well and broke rather than changed shape after a certain force was applied. I believe that these aforementioned properties make it the ideal candidate for insulation products, anti-impact products, children’s toys, friction reduction, or even as a use in artistic products.

            As an insulator, this would hold its shape very well, and it would absorb heat given off by whatever source one chooses and then keeps it there, creating a barrier of heat between the two materials it separates.

            As an anti-impact product, it would serve best, perhaps in the bottoms of peoples’ shoes: as it absorbs the normal forces of every day walking, it would retain its shape after the depression, and thus allow the person to more comfortably walk around for extended periods of time. It also has much of the consistency of human flesh, and as such could be used as ballistics gel for testing.

            As a children’s toy, it would only be used in hardened format. It does not scrape off easily, however can be broken, thus I would recommend It only be made in this manner in large single blocks, and recommend that no children under 6 be allowed to play with it.

            As an artistic product, I believe we could offer it in kit format, with the ingredients to make it and instructions on how to create and mold one’s own shapes out of this polymer.

Also: to make a suitable amount in our 6000L reaction vessel, we will need to put roughly 3000L of sta-flo and 3000L of plyvinylacetate/polyvinyl alcohol bloc copolymer.

Under the assumption that it would take 10 minutes per 65 mL as in our experimentation, it will take anywhere from 10 minutes to 153 minutes per batch to create, and about 3 hours per hardening session, based on the amount of mixing and baking that the polymer would be subjected to.
