Nowadays, many cooking utensils are made of polymeric materials. However, people believe that heating plastic utensils would cause harm such as releasing toxic substances. Hence, people are looking for other alternatives to replace plastic. Choose ONE cooking utensil (spatula) and identify the suitable material that will satisfy its criteria. Justify your answer. Your discussion must include the interrelationship between structure-properties-processing of the selected cooking utensil.
