Polymer

Polymer is what its name implies, it’s a polymer, what plastic/rubber is. Polymer is used in almost all complex machines. Very useful.

Production
Polymer bars can be made with Petroleum Gas, Fluorite, and Coal in a Chemical Plant.

Properties
A polymer is basically plastic/rubber.

Polymer melts at relatively low temperatures.

The polymer acts as an insulator for electricity.

Uses
Polymer is used in many machines, items, and even NTM added music discs. Polymer bars can be shredded into Polymer Powder using the Shredder and resmelted back into an ingot form.

It can be used in a wide variety of tools and useful machines, including electric tools when used with High-Speed Steel.

It can be used to make Insulators by placing two in a row in your 2x2 inventory crafting grid.

Trivia

 * Polymer is just a different name for any plastic/rubber.
 * Its texture doesn’t actually look like an ingot, it’s more like a flat slab, likely why it was renamed to a "polymer bar" instead.
 * It is canonically Polytetrafluoroethylene (Teflon).
