How many types of plastic are there?
To summarize, there are 7 types of plastic exist in our current modern days:
- 1 – Polyethylene Terephthalate (PET or PETE or Polyester)
- 2 – High-Density Polyethylene (HDPE)
- 3 – Polyvinyl Chloride (PVC)
- 4 – Low-Density Polyethylene (LDPE)
- 5 – Polypropylene (PP)
- 6 – Polystyrene (PS)
- 7 – Other.
How do you test plastic type?
One of the simplest ways to carry out a flame test is by cutting a sample from the plastic and igniting it in a fume cupboard. The colour of flame, scent and characteristics of burning can give an indication of the type of plastic: Polyethylene (PE) – Drips, smells like candlewax.
What are the components of plastic?
The term “plastics” includes materials composed of various elements such as carbon, hydrogen, oxygen, nitrogen, chlorine, and sulfur.

7 Different Types of Plastic
- Below is 7 of the most popular and commonly used plastics:
- Acrylic or Polymethyl Methacrylate (PMMA)
- Polycarbonate (PC)
- Polyethylene (PE)
- Polypropylene (PP)
- Polyethylene Terephthalate (PETE or PET)
- Polyvinyl Chloride (PVC)
- Acrylonitrile-Butadiene-Styrene (ABS)
What is the difference between PP and HDPE?
Density is a key factor that differentiates HDPE from PP. Because HDPE has a lower density, it can be more rigid. Thanks to its lower density, though, PP, can be used when moulding parts with lower weight. Like HDPE, Polypropylene offers good chemical resistance.
What are the two types of plastic?
The two key categories of plastic are thermoplastics and thermosetting plastics (thermosets). Thermoplastic products have the ability to be continually softened, melted and reshaped/recycled, for instance in injection molding or extrusion resins.
