Plastic is a material that we all take for granted because it is so commonplace in our lives today. Yet, what most of us don’t think about is that every plastic product that we benefit from or make use of utilizes plastic that was compound for its specific purpose. Without compounding, plastic wouldn’t be nearly as versatile and readily available to serve our multitude of needs.

Compounding plastic is done differently for every application. Some of the factors that are specifically compounded for include but are not limited to:
Color. When you are compounding plastic color selection is often a priority. When you think of all of the plastic products you use, you’ll realize that it is available in an unlimited number of colors.
Food safe. Not all plastic is food safe. When plastic will be used for food packaging or handling, specific products, and compounding processes must take place to ensure that it is safe to encounter a food product that will be consumed.
Fire retardation. When exposed to heat, plastics will melt and often catch fire. Fire retardants can be added to polymers to help prohibit combustion, especially in construction applications.
Strength and flexibility. Just thinking about the plastic products that you use daily; you’ll notice there are differences in strength and flexibility. Each of these plastics has been compounded to provide for this extremely specific purpose and quality.
Antimicrobial properties. Some plastic products benefit from being compounded to prohibit the growth of germs on their surface. These plastic additives are especially prevalent in the production of medical products.
UV Tolerance. If plastic products are exposed to UV rays, the plastic can be compounded to add extra protection against these rays that often lead to degradation of the material.

The four most common types of polyethylene are described below:
Polyethylene’s many benefits include:
Yes, polyethylene is widely used for plastic injection molding. It is one of the easiest materials to work with. Its processing ease makes it popular in other applications as well, such as blow molding and film extrusion. For more information, see our guide on Plastic Injection Molding.
Polyethylene is a thermoplastic and as such is not used in plastic but is rather a plastic itself.
No, polyethylene is not environmentally friendly. Like most thermoplastics, polyethylene is produced as a crude oil processing by-product and is not biodegradable. In fact, a large percentage of plastic pollution is due to discarded polyethylene films and bags.
The difference between polypropylene (PP) and polyethylene (PE) is in the makeup of their polymeric chains. Polypropylene molecular chains are made from repeating propylene (C3H6)n monomers, whereas polyethylene chains are made from repeating ethylene (C2H4)n monomers. To learn more, see our guide on Polypropylene vs. Polyethylene.
Polyethylene (PE) and polyethylene terephthalate (PET) are entirely different polymers, manufactured differently, and used for different applications. PET, with the chemical formula (C10H8O4)n, is produced from the polymerization of ethylene glycol and terephthalic acid, while PE ((C2H4)n) is produced from the polymerization of ethylene. Polyethylene is often used for making plastic films or containers, whereas PET is more typically used in fibers. It is more commonly known as polyester. For more information, see our guide on Polyethylene Terephthalate.
