Polyethylene is a polymer of ethylene. It is non-toxic and easily recycled.
Synthesis
Polyethylene is produced in industrial quantities through the use of catalysts. Common catalysts include chromium trioxide and metallocene. Polyethylene can be produced in-situ using Ethylene as feedstock. The embodied energy of polyethylene is about 100 MJ/kg, depending on the variety. Polyethylene is a synthetic material, and is the most common plastic produced on Earth. This may be true on Mars as well.
