the-difference-between-types-of-plastic-sheets

If you work with plastics, you’re probably familiar with their general properties. However, when we talk about "plastic sheets," we're referring to a broad category of materials, each with unique characteristics and uses. At Sheet Plastics, we will guide you through the different types of plastic sheets, including acrylic, polycarbonate, PETG, HDPE and fluted polypropylene plastic sheets.

What are Plastic Sheets?

Plastic sheets are a flat, continuous piece of plastic starting from 1mm in thickness. They come in many different types of plastic materials, offering strength and flexibility. Plastic sheets can be clear, coloured, smooth, rough or even semi-transparent, depending on the job they’re needed for. Because of this versatility, they’re used in a wide range of industries.

Types of Plastic Sheets:

Acrylic Plastic Sheets

Acrylic sheets are a popular choice for many applications, often used as a lightweight, shatter-resistant alternative to glass. They offer the same clarity, brilliance and transparency as glass but are half the weight and have a much greater impact resistance. 

Uses of Acrylic Plastic Sheets

You’ll likely see these sheets in: 

  • Signage
  • Display cases
  • Glazing for windows and greenhouses
  • Splashbacks
  • Skylights

Acrylic is stronger and much more impact-resistant than other plastic materials. However polycarbonate outperforms acrylic with an impact strength that is 250 times greater than glass. Learn more about the difference between acrylic and polycarbonate sheets in our extensive guide.

Polycarbonate Plastic Sheets 

Polycarbonate sheets are a thermoplastic, which means they can be melted and reshaped when heated and then solidified again when cooled. Known for its exceptional strength, it withstands outdoor conditions such as UV rays and high temperatures. While polycarbonate is virtually unbreakable, it’s still light-weight and can be easily cut into various shapes.

Uses of Polycarbonate Plastic Sheets

You’ll likely find polycarbonate sheets in:

  • Safety glazing
  • Machine guards
  • Roofing and skylights
  • Protective barriers

Polycarbonate can be interchangeable with acrylic as they both are strong materials. However, polycarbonate is always the better choice for applications where safety and security are a priority. 

PETG Sheets

PETG stands for polyethylene terephthalate glycol, a type of transparent plastic sheet. Made from a thermoplastic polyester, these clear sheets provide high impact strength and chemical resistance. Clear PETG sheets offer great light transmission if you’re looking for an alternative to glass. Known for their ability to withstand high temperatures and durable properties, they are ideal for both indoor and outdoor use. 

Uses of PETG Plastic Sheets

You’ll likely find these sheets in everyday applications such as:

  • Protective barriers
  • Splashbacks
  • Signage and displays
  • Glazing

PETG sheets are stronger and more impact-resistant than other plastic materials, such as acrylic. They are also a cheaper alternative to polycarbonate. However, polycarbonate still outperforms PETG with its impact strength.

HDPE Plastic Sheets

HDPE (High-Density Polyethylene) is a strong and rigid thermoplastic material. Made from petroleum, these sheets are one of the most versatile materials and are widely used across many industries. Known for their excellent strength-to-weight ratio, HDPE sheets are lightweight yet incredibly tough. They excel in resistance against chemicals and moisture.

Uses of HDPE Plastic Sheets

You’ll likely encounter HDPE sheets in:

  • Food preparation surfaces (cutting boards)
  • Chemical storage tanks
  • Piping systems
  • Playground equipment

HDPE has great chemical resistance, which makes it ideal for food-related applications. However, acrylic and polycarbonate offer greater clarity and rigidity, making them better suited for applications requiring transparency and higher heat resistance.

Fluted Polypropylene Sheets

Fluted polypropylene sheets are made from polypropylene plastic. They have a corrugated design, featuring a layered structure with hollow channels. This makes them even lighter while maintaining strength. Their design is very similar to cardboard and these sheets can be cut by hand or with a laser cutter.

Uses of fluted polypropylene sheets 

Fluted polypropylene sheets are often used in:

  • Outdoor signs and displays
  • Temporary protective barriers
  • Lightweight construction panels
