What is Plastic Granules ?

Granular raw material appears as a thermoplastic polymer type. Plastic granules, which are generally produced from polymers, are used in many industrial applications due to their low cost. Plastic granules are produced by converting the monomer propylene into polymer form by various processes.

1) Polyethylene Terephthalate (PET or PETE)

Polyethylene terephthalate (pet) is the most common thermoplastic resin of the polyester family, PET is the fourth-most produced synthetic plastic in the world. Polyethylene (PE) Terephthalate or PET is also known as a wrinkle-free fiber. It’s different from the plastic bag we commonly see at the supermarket.

This type of plastic polymer is mostly used for food & drink packaging purposes, due to its strong ability to prevent oxygen from getting in & spoiling the product inside. It also helps to keep the carbon dioxide in carbonated drinks from getting out.

2) High-Density Polyethylene (HDPE).

HDPE is a rigid, tough and strong material with a hazy, frosted appearance. HDPE has good resistance to stress cracking as well as high impact strength. HDPE is Quite unique compared to the other types, HDPE has long virtually unbranched polymer chains which makes them really dense & thus, stronger & thicker from PET.

3) Polyvinyl Chloride (PVC or Vinyl).

Polyvinyl chloride is the world’s third-most widely produced synthetic polymer of plastic. About 40 million tons of PVC are produced each year. PVC comes in rigid and flexible forms. Rigid PVC is used in construction for pipes, doors and windows. Polyvinyl Chloride is typically used in toys, blister wrap, cling wrap, detergent bottles, loose-leaf binders, blood bags, and medical tubing.

4) Low-Density Polyethylene (LDPE).

As said before, Polyethylenes are the most used family of plastics in the world. This type of plastic has the simplest plastic polymer chemical structure, making it very easy and very cheap to process. LDPE polymers have significant chain branching including long side chains making them less dense and less crystalline (structurally ordered) and thus a generally thinner more flexible form of polyethylene.

5) Polypropylene (PP)

Polypropylene, also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Polypropylene Plastic Type (PP) are Stiffer and more resistant to heat, PP is widely used for hot food containers. Its strength quality is somewhere between LDPE and HDPE. Besides in thermal vests, and car parts, PP is also included in the disposable diaper and sanitary pad liners.

6) Polystyrene (PS or Styrofoam)

Polystyrene is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. Polystyrene (PS) is the styrofoam we all commonly used for food containers, egg cartons, disposable cups and bowls, packaging, and also bike helmet.

7) Acrylonitrile-Butadiene-Styrene (ABS)

Acrylonitrile butadiene styrene is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C. ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene.
