According to Guinness World Records, this is the best-selling book of all time.
What is the Bible?
This is the name of the recycling process that breaks down the polymer to the point that it returns all the way back to the original monomers.
What is chemical/advanced/feed stock recycling?
This type of foam cell structure only allows gases or liquids to move by diffusing through the polymer.
What is closed cell?
The rate-determining step within the extrusion blow molding process.
What is the inflation/cooling step?
Injection molding is typically reserved for high volume applications and is known for high this which is why is used to make closures with threading.

What is life cycle analysis?
This type of polymer is typically used for foam-in-place.
What is polyurethane?
This blow molding process is typically used when a thin, tall structure is desired.
What is stretch blow molding?
This is an adjustment we can make to the runners in the injection molding process to increase production speeds.
What is heat the runners?
Genie from Aladdin complained that being cooped up in a lamp gave him such a crick in his neck. Just how long was he in there?
