What makes Plastic a Durable Chemical?
Plastic has made its presence important in our daily lives. It is used for a large number of purposes, and if you ask the Plastic resin suppliers, the advancements in its manufacturing process will only allow it to dig deeper roots in our lives. However, do you know how this material is manufactured? Let us have a look at its manufacturing process.
Plastic is one of the most commonly used materials as it is easily available, affordable and fairly durable as well. But have you ever wondered how this plastic is manufactured in a variety of colors and molded into various shapes? This article is created to provide you with an overview of its manufacturing process.
What is Plastic?
Plastic is a type of man-made polymer. It is made up of chlorine, nitrogen, hydrogen, oxygen, carbon, and sulfur. The molecules of all these elements are firmly held together for the purpose of creating plastic molecules. It was initially manufactured from sap that is found in plants, animal shells and from the secretions of small insects.
It was in the year 1969 that American inventor Wesley Hyatt used cellulose and camphor to create synthetic plastic. Initially called as celluloid, it quickly became a staple for manufacturing dentures, combs, and other small articles.
Then in the year 1951, two chemists discovered polyethylene and polypropylene and this discovery is single-handedly responsible for the existence of plastic in our daily lives. A large number of companies started manufacturing plastic products, also giving rise to many polyethylene suppliers.
Some of the most common ingredients of our modern day plastics are-
• Crude oil
• Natural gas
Polymerization and Polycondensation are two of the most important processes for producing plastic. A variety of catalysts are used in this process, and monomers like propylene and ethylene are used to form long chains. There are Plastic resin suppliers that supply the basic ingredients as well as the monomers to the companies that manufacture plastic products.
Types of Plastics
Thermoplastics and Thermosets are the two main categories in which the modern plastics can be divided. PVC (Poly-Vinyl Chloride), EPS (Expanded Polystyrene), PS (Polystyrene), PC (Polycarbonate) and ABS (Acrylonitrile Butadiene Styrene) are some of the examples of Thermoplastics. EP (Epoxide), PUR (Polyurethane), PTFE (Polytetrafluoroethylene) and PF (Phenol Formaldehyde) are the common examples of Thermosets.
Even though each type of plastic has its unique characteristics, most of them have some common characteristics as mentioned below:
• They can function as both electric and thermal insulators.
• They are highly resistant to chemicals.
• They are generally light in weight and have different strengths.
• They can be processed in a variety of ways for manufacturing intricate parts or fibers.
• Polymers are generally made from petroleum.
With its growing importance on both, domestic as well as industrial level, plastic is replacing many other materials due to its flexibility and affordability. A large number of plastic manufacturers and Plastic resin suppliers are flourishing and providing users with highly durable products that are much cheaper than other materials.
