The Chemistry of Plastics Molecular Model Set The basic raw materials for plastic are petroleum and/or natural gas. These fossil fuels are sometimes combined with other elements, such as oxygen or chlorine, to make different types of plastic such as soft drink bottles, grocery bags, and cups. The Chemistry of Plastics Molecular Model Set allows students to construct the repeating unit for each of six plastics. The Plastic Identification Coding System can be used to identify the plastic items with recycle numbers 1-6. Students can investigate the physical properties of the plastic items, and draw conclusions about the relationship of the molecular structure to the properties and recycling of each plastic. Contents - 7 plastic items with Plastic Identification (recycle) Codes 1-6. There are 2 items with recycle code number 1.
