Three cutting boards made of high-density polyethylene lay side-by-side on a countertop.

Polyethylene (PE) and polypropylene (PP) are both thermoplastic polymers, each possessing distinct properties and applications. When comparing polypropylene to polyethylene, it is crucial to recognize that they serve different purposes and are not always interchangeable. Polyethylene is derived from the polymerization of ethylene, while polypropylene results from the polymerization of propylene. Understanding these differences is […]

Low-volume injection molding is the best option if you are looking to make parts in quantities of 100,000 or fewer. It’s used for mass-producing identical parts before committing to a long-term molding setup, whereas other parts may never need to be produced in higher volumes. This form of molding is one of the most common […]
