It is hard to imagine modern life without plastic. The durability, lightness, toughness, low cost and most importantly resistance to corrosion make plastic one of the most reliable material for manufacturing thousands of products of day-to-day and industrial use. Starting from the plant material cellulose in 1869, the synthetic plastic technology reached the petroleum-to-plastic stage in 1951 when the discovery of polyethylene and polypropylene took place. Today PE PP inter polymer pallets act as a driving force behind the manufacturing of a majority of plastic products. PE PP Inter Polymer Pellets
Petroleum to Plastics Journey The plastic we use today has its root in crude oil wells. In the journey from well to home, it passes through fascinating technological processes. Let us experience this journey to understand the petroleum to plastic process:
It begins with the drilling of crude Oil Field Chemicals and transporting it to a refinery.

Here it is refined into hundreds of petrochemical products including propane and ethane.

Then propane and ethane passes through the cracking process to get converted into ethylene and propylene.

Adding catalyst to propylene or ethylene in a reactor gives a powdered material, the polymer.

The use of additives then combines polymer in a continuous blender. Next, the polymer is melted in an extruder.

The polymer is put to cool down so that it could be moved to a machine to change it into small pellets.

As a result, you get the PE PP inter polymer pellets shipped to your unit. Here, these pellets find their use for manufacturing plastic product through processes like injection molding, extrusion, blow molding and more.
Type of Polyethelene 1. Polyethelene The most widely used plastic on earth is Polyethelene (PE). The ability of PE to be used in several density ranges makes it popular among manufacturers. Industries use it for manufacturing bulletproof vests and disposable plastic used in packaging. It all depends on tweaking the polymer chain which results in variation in the density. Here are some of the varieties of PE plastics:
Low-density polyethylene (LDPE): It is developed with both the short and long branches in the polymer chains to give it the desired flexibility.

Linear Low-density polyethylene (LLDPE): The technology is the same as LDPE, but it has more linear chains with several short side branches.

High density polyethylene (HDPE): It mainly consists of straight chain molecules. Since there are no side branches, it is tightly packed, hence giving it more strength and durability.

Ultrahigh molecular weight polyethylene (UWMPE): The technology makes it possible to keep extra long chains. This gives it the higher tensile strength, making it suitable for high impact use like bulletproof vests.
2. Polypropelene Popularly known as "prope" in the plastic industry, the strength, flexibility and durability makes Polypropylene (PP) one of the most adjustable thermoplastics. Compared to PE, PP gives better results when exposed to heat and high stress. Since PP is easier to injection mould and more resistant to acids it finds applicability in more challenging environments. Globally, PP is the second most manufactured plastic. Can we imagine a day without plastic? Possible, only if you are deep inside the Amazon forest. The word plastic, meaning "able to be molded" itself is the solution to all the industrial and individual necessities. The lightness, strength, durability makes PE PP inter polymer pellets based plastics absolute must for proper functioning of the modern world. Technically, it is not the plastic, but the use of plastic that makes it hazardous for the environment.
