per pound,” says Innes. “However, understanding and applying the differences in usage levels and calculating the cost contribution to the formulation shows that Product B which contributes a cost of only $0.09 per pound is actually by far the less costly approach. “Business managers with an eye on the bottom line

product technology is the price/performance issue. Specifically, purchasing agents and formulators must understand fully how to compare new products to determine the actual cost to their business units. One consultant in this area, Flame Retardants
Associates, says it repeatedly finds that pricing of flame retardant additives used in thermoplastics is not well understood. It says that it recently received an inquiry for pricing on a sulphonate FR for polycarbonate from a purchasing agent in Asia. “The problem is that this agent was about to make his FR selection on a direct and simple dollar per kilo comparison. There was no comprehension of the need to consider loading level typically used,” says Ann Innes at the consultancy firm. Table 1 shows how loading level affects price
comparisons of FR additives. “A selection of FR Product A or B based solely on a simple price per pound compari- son would result in the selection of Product A at $5.00
must make sure their purchasing agents and formula- tors are provided with adequate guidance on how to cor- rectly assess price comparisons for any thermoplastic additives. Another very important cost comparison factor, particularly for complicated injection moulding thermoplastic compounds, is specific gravity. The cost assessor (purchasing agent and/or formulator) must understand how to accurately compute the effects of specific gravity of formulation components on the cost contribution to the injection moulding compound as well as the loading level effects explained above. “
