Description

Injection molding requires pellets that roll into the machine.
Polystyrene pellets yield a rigid project.
Polyethylene is a translucent self lubricating plastic.
Low density Polyethylene is pliable and is used for projects that require some flexibility.
High Density Polyethylene is used for rigid projects that do not require flexibility.
Polypropylene has similar properties to polyethylene but is stronger.
