How a Plastic Ruler is Made
By: Evan Kennedy
The Plastic
The Plastic
-Plastic which is mainly made of silicone extracted from crude oil.
-Crude oil is extracted from fossils.
Polymerization
Polymerization
Polymerization is the process of reacting small chemical units, called monomer molecules, together in a chemical reaction to form polymer chains or three-dimensional networks.
Polymerization is the process that gives us silicone from crude oil.
Melting
The plastic is heated to its melting point, which is just over 300 degrees celcius (about 575 degrees farenhiet).
Melting
Mold It!
The melted plastic is sent into a 13 by 1.5 by .1 (inches)mold.
Manufacturing
Refining
The ruler is then refined from the mold into a 12.5 by 1 by 0.0625 (inches) ruler
Refining
Selling
Rulers are shipped around the world by truck, airplane and ships, and sold to supply stores who sell them to us.
