The client wanted the plastic to satisfy certain requirements. Some of these requirements are: anti-corrosive, stable in hot water, chemically resistant to bleaches and waxing compounds, inexpensive, and safe. The table below lists these specifications.

Table 2 - Specifications Table Changes D or W Importance (1=Low 10=High) D temperature ranges 40F(cold) to 120F(hot) D resistant to bleach D resistant to waxing compounds D resistant to detergent D behaves as stainless steel(finished and annealed) with corrosives D stainless steel characteristics D manufacturing cost < or = D safe . . W similar mechanical properties as stainless steel - finished and annealed 10 W similar thermal properties as stainless steel - finished and annealed 10 W similar physical properties as stainless steel - finished and annealed 10 W similar chemical properties as stainless steel - finished and annealed 10 W similar fabrication properties as stainless steel - finished and annealed 10

The table shows that the plastics should be resistant to chemicals such as detergents, bleaches and waxing compounds. The table also shows that cost is a major factor since the manufacturing (or processing) cost of the plastic should be less than or equal to that of the stainless steel. The thermal and chemical properties of the plastic should also be similar to that of the stainless steel as reflected in the rating of 10 (high).
