Dual-Sided Plastics Property and Material Cost Comparator
- 1950
A comparator device constructed from two rotating cardboard wheels attached to a cardboard cover. One side displays plastic properties and the other displays the material costs for products manufactured by the Monsanto Company. On the plastics side, two cutouts show mechanical, thermal, optical, electrical, and chemical property data based on the wheels' orientation. The material cost side compares polymer and "alternate material" products; the two cutouts display pricing data based on the quantity and form of material.
