Plastics, or polymers, as they are sometimes called, are one of the most used raw materials in the world. They are used to make several things, from the now essential face masks to bulletproof vests. There are several types of plastic granules. Some of them are polypropylene granules (PP granules), polyethylene granules (PE granules), electret masterbatch, polystyrene granules (PS granules), and polyvinyl chloride granules (PVC granules). Below is a detailed explanation of what some of these plastic granules are, their properties, applications, advantages, and production methods.

Polypropylene, also called polypropene, is a thermoplastic polymer produced through the polymerization of propylene gas in the presence of a catalysts system. This gas is one of the by-products of crude oil and natural gas. It can be produced in various molecular weights by modifying the polymerization conditions while producing it. They are usually used in the form of pellets, powders, fibers, and plastic granules for manufacturing other items.


Advantages


It is resistant to a lot of chemical solvents, diluted acids and bases included.

It has a high enough resistance to heat, with a melting point of 160 or 170 degrees Celsius.

It can be dyed to give different colors.

It has high tensile strength and an optimal weight-strength ratio.

It has high flexural strength due to its semi-crystalline nature.


Applications


Being as popular as they are, polypropylene is used to manufacture a lot of things. Some of them are carpet fiber, automotive components, ropes, thermal underwear, stationery, reusable containers, laboratory equipment, polymer banknotes, packaging application, medical equipment, and so on. Polypropylene is also used in the production of melt-blown non-woven fabrics.

Polyethylene, polyethylene, or polythene is a thermoplastic polymer produced from the polymerization of propylene gas in the presence of a catalysts system. This gas is also one of the by-products of crude oil and natural gas. It is the most popular thermoplastic used with a wide range of applications due to its various types.


Polyethylene can be classified into several types:


Low-Density PE (LDPE)

High-Density PE (HDPE)

Linear-Low-Density PE (LLDPE)

Ultra-High Molecular Weight PE (UHMWPE)

Ultra-Low Molecular-Weight PE (UHMWPE)

High-Molecular-Weight PE (HMWPE)

High-density cross-linked polyethylene (HDPE)

Cross-Linked PE (PEX or XLPE)

Very-Low-Density PE (VLDPE)

Chlorinated PE (CPE)


Like polypropylene, they are usually used in the form of pellets, powders, fibers, and plastic granules for manufacturing other items. PE is one of the most common types of granules.


Advantages


Polyethylene has several advantages depending on its variant.

LDPE (virgin ldpe granules) is a flexible material with high ductility but low tensile strength. This makes it suitable for the production of shopping bags and plastic films.

HDPE (virgin hdpe resin) has a highly crystalline structure that makes the plastic rigid. This makes it suitable for producing things like garbage bins, cutting boards, and so on.

UHMWPE is a very dense variant of polyethylene. It has a very high tensile strength and is usually incorporated into bulletproof vests and high-performance equipment.


Applications


PE is used to manufacture plastic bags, cling films, bottle containers, toys, flasks, buckets, cisterns, flexible tubing, basins, and so many other things.
