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 manufacture. Plastics are used in constructing wholesale plastic vials, plastic containers and plastic cosmetic jars and, therefore, understanding the various types of plastic 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, polystyrene is a great plastic product. It makes tough plastic for utensils, furniture and cabinets for television sets and monitors. It is an excellent insulator, moldable and light in weight and is made rigid and transparent.
You would find polystyrene plastics everywhere; at home, in the office, medical industry, shipping, and packaging.
This polymer of polypropylene monomers has many diverse uses. It is used to make plastic bags, plastic containers, hinged-lid containers, pharmacy vials, plastic jars, and storage for liquids or solids.
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. It is also resistant to many chemicals making it ideal for storing certain liquids. It is resistant to corrosion by both - bases and acids.
Polypropylene is light and has average to zero transparency and is, therefore, the most common material used as a small plastic packaging container.
Polyethylene is the most commonly used plastic polymer. 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.
• High-density polyethylene (HDPE) - Sturdy and translucent. It 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.
• 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 retail, laboratory uses, electronics packaging, or packaging and storage of small items - plastics will always have a place.
