En polymer er et makromolekyle, der sammensat af mange ens byggestene. Plast tilhører familien af polymere materialer. Plast tilhører familien af polymere materialer. De enkelte plasttyper kaldes derfor også ofte for polymerer. Betegnelsen stammer fra det græske “polymeros”, der kan oversættes til poly = mange og meros = dele.

1.2. Definition Plastic covers a range of synthetic or semisynthetic polymerization products. Plastics are polymers: long chains of atoms bonded to one another. All plastics are polymers but not all polymers are plastics; there are actually few natural polymers. Nature has always produced polymers such as cellulose, the DNA molecule and proteins.

Vid höga temperaturer sönderdelas helt enkelt polymerkedjorna. The video discusses difference between polymer and plastic. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function.

We are one of the Nordic region's leading distributors of raw materials for the plastic industry.

The first plastic material was based on nitrocellulose and was contains one of the two alternative marking symbols.

Polymer element availability. The team is in the process of updating the Polymer elements to use the new "hybrid" format compatible with both Polymer 1.7+ and 2.x. The following elements have been updated to support Polymer 2.0, or require no updates: app-layout How are plastics made?

Plastic is a specific type of polymer. Plastics are synthetic and do not occur naturally. With this in mind, we can dig a little deeper into the definitions. Differences between polymer and plastic?
