Uses of polystyrene, polyethylene and polypropylene plastics

Choosing containers made of the right materials is crucial in ensuring durability and quality. There are many elements that make the products we use ranging from glass to plastics. Plastics are used in making many daily-use and construction products and, therefore, understanding the various types is essential before you buy a container.

Plastics are mainly categorized into two:

1. Thermosetting plastics or thermosets- these retain their shape, and they neither bend nor return to their original shape even on heating. They are used as aircraft parts, auto parts and tires because they are hard and long-lasting. Examples of thermosets are phenolic resins, epoxy resins, polyesters and polyurethanes.

2. Thermoplastics- these are more flaccid than thermosets and change their shape when heated that is, they return to their original forms. They can be easily modified and molded into packaging, fibers and films. Examples of thermoplastics are polystyrene, polyvinyl chloride, polyethylene and polypropylene.

Each plastic is used for a different purpose depending on its characteristic. Thermoplastics, for instance, are used to make applications such as packaging and storage goods, consumer goods, machine parts and medical equipment.


Polystyrene is a polymer of monomers known as styrene manufactured in many different forms each of which has different functions. It makes tough plastic for utensils, furniture and cabinets for television sets and monitors. It is an excellent insulator, moldable and light in weight. Polystyrene is made rigid and transparent but when heated and air blown into it, Styrofoam is made.

You would find polystyrene plastics anywhere; at home, in the office, medical industry, and for plastic vials and containers. It has diversified uses ranging from construction to manufacturing and packaging. The various forms are used explained below:

• Expanded polystyrene foam (EPS) makes good insulation materials. Packaging materials such as foam peanuts that are used to cushion fragile product are made from EPS. Glass, electronics and chemicals are kept safe by EPS during packaging.

• Extruded polystyrene (PS) mainly used to make DVD and CD cases, plastic car or boat models, smoke detector housing and disposable cutlery and our plastic vials.

• Styrofoam or extruded polystyrene foam (XPS) is used to make cups and plastic vials for heated drinks and architectural models.

• Polystyrene copolymers used for making product casings and children toys.


This polymer of propylene monomers has many diverse uses. In medicine, it is used to make heat-resistant equipment and small storage containers. Stationery folders, as well as packaging boxes, are made from polypropylene.

Other uses of propylene include the production of car batteries, drinking straws, and ropes. You will even find bags, diapers, reusable plastic containers, and bottle caps made from polypropylene. Plastic moldings, hinged-lid containers, pharmacy vials, plastic jars, filters for gases and liquids, and insulation for electrical cables are from of polypropylene.

It is resistant to high temperatures and therefore it is suitable to be used in dishwashers and microwaves as well as food and beverage storage and reusable bags. It is also resistant to many chemicals making it ideal for making laboratory equipment. It is resistant to corrosion by both - bases and acids.

Polypropylene is light and has excellent transparency and is, therefore, the most common material used as a packaging container. It is recyclable unlike polystyrene because it has no bleach or aromatic compounds..


Polyethylene is the most commonly used plastic polymer. It is made up of monomers of ethyne in a condensation process involving loss of water molecules. Various types of ethylene are available categorized according to their density and molecular structure. The uses vary according to these types.

• Ultra high molecular weight polyethylene (UHMWPE) - this is not easily corroded by chemicals and is a tough material. It is used to make products such as bearings, gears, other moving machine parts, bullet proof vests and artificial joints for healing secondary fracture in medicine.

• High-density polyethylene (HDPE) - this is used as a material for the manufacture of water pipes, detergent bottles, margarine tubs, milk jugs and other types of plastic jars. It is sturdy and translucent and does not leach. It is resistant to ultra-violet radiation that could decolorize the material and can withstand extreme temperatures ranging from -100 to 80 degrees Celsius. This makes HDPE ideal for being used in microwaves and fridges.

• Medium-density polyethylene (MDPE)- this makes bags, gas pipes, disposable gloves, fittings, and packaging films.

• Low-density polyethylene (LDPE) - this is the softest and most flexible and is, therefore, used to produce sacks, sheets, jars and squeeze bottles. It can float on water or alcohol when placed in it, and for this is the reason it is referred to as low density.

Polyethylene is recyclable in which serves to ensure that the environment is preserved and free from pollution. It degrades quickly making it ideal for disposable items, and at the same time, it is sturdy enough for regular-use items.

Polyethylene, polystyrene and polypropylene are an important part of our daily lives. They have all sorts of applications from our homes to offices to industries. Whether it is for development, medical uses, electronics, appliances or packaging and storage - plastics will always have a place.

Plastics play an important role in every aspect of our lives especially with improving technology. In the pharmaceutical industry, they have played an important role in developing top notch equipment to be used in diagnosis and treatment of life-threatening diseases. They are used for storage of chemicals as well since they are resistant to corrosion by most of them. In packaging, they are the most widely used materials due to their flexibility and versatility.

Plastics are vital to our living comfortably. However, care should be taken when handling them since they can be very hazardous.
