Step 2: Find a Plastic that Will Work. Based on the end product and its use, determine the best plastic resin to use. Step 3: Determine the Shrinkage. When plastic is injected into the mold, it immediately begins to cool causing a certain amount of shrinkage.

What is Plastic Resin? - Plastinternational

Some of these liquids can be used to create plastic once they are altered through a process called cracking. Basically speaking, plastics are the result of molecules called hydrocarbons being encouraged to create chains, called polymers. To create these hydrocarbon chains, a compound (or monomer) such as ethylene (also called ethene) is placed under heavy pressure and mixed with a catalyst until it forms a liquid that eventually becomes the plastic pellets aka. Resin.
