Polypropylene Sheet VS Polyethylene Panel


Polypropylene Sheet and Polyethylene Sheet have considerable advantages. In addition to being very flexible, they also moderately impact resistant, which means there is no need to worry about strength when using these polymers. In addition, both polymer sheets are heat-resistant and have almost 0 toxicity to the human body. If you use plastics for food and beverage containers, their eco-friendly and non-toxic properties are worth considering.

Advantages of PP sheet and PE sheet

Polypropylene panels:
  1. It contains good fatigue resistance and therefore has good impact strength.
  2. This is a lower-cost material.
  3. PP solid sheet has high flexural strength due to its semi-crystalline nature.
  4. It’s easier to repair from damage.
  5. It has good chemical resistance to various bases and acids.
  6. It is resistant to electricity and is, therefore, an excellent electrical insulator.
  7. Polypropylene is very moisture resistant.
Polyethylene boards:
  1. While polyethylene is an excellent electrical insulator, it can pick up static electricity.
  2. Depending on its specifications, it can be almost transparent to opaque.
  3. Its heat-resistant properties allow it to be used at high and low temperatures.
  4. Polyethylene can be recycled into other products.
  5. Polyethylene is durable and waterproof, and it lasts longer when exposed to the elements compared to other polymers.
  6. Its low density makes it suitable for packaging.
  7. Although it has low strength and hardness, it is very malleable and has high impact strength, allowing it to stretch rather than shatter.

The shortcoming of Polypropylene Sheet and polyethylene panel

PP plastic sheet:

It is difficult to paint due to its weak adhesion. But Polyflutey already has the technology to improve it. Despite its flaws, polypropylene is an excellent material. It has a unique combination of properties not found in any other material, making it ideal for a variety of tasks.

PE plastic sheet:
  • Producing polyethylene consumes a lot of energy and results in massive emissions of carbon dioxide, a greenhouse gas that contributes to global warming and climate change.
  • It takes a long time to degrade and can remain in landfills for decades.
  • The recycling process is complex and can take a long time.
  • Polyethylene is mainly derived from petroleum or natural gas with limited resources.

Chemical properties of PP solid sheet polypropylene plastic board

PP sheets are made from polypropylene, a harder thermoplastic polymer than polyethylene. Polypropylene contains propylene monomer units consisting of tricarbon alkane units [–CH2(CH3)CH2]. Due to its rigidity, it is often used in the manufacture of molding materials. Although polypropylene is not as transparent as polyethylene, it may be translucent by removing color. Polypropylene sheet is most commonly a solid flat or hollow lattice structure, depending on the application and process. The density of most polypropylene panels is between HDPE sheets and LDPE plastic sheets.

Chemical properties of PE sheet

PE board is a board made of polyethylene, which is expected to be a solid flat plate. Polyethylene is a polymer composed of ethylene molecules composed of two carbon alkane units [-CH2CH2-]. It is a thermoplastic polymer. There are many types of polyethylene panels. Such as UHMWPE sheets, HDPE boards, MDPE sheets, LDPE plastic sheets, etc. Additionally, the sheets are known for their chemical resistance as they do not react with strong acids or bases when exposed. Polyethylene is a chemically inert and transparent material, which means that unlike transparent materials, it allows light to pass through without creating an image. Copolymerization of ethylene is possible, but it compromises its purity. However, compared to other polymers, polyethylene is less susceptible to copolymerization. As a result, ensuring its purity is often more expensive.

Difference Between Polypropylene and Polyethylene

Polyethylene and polypropylene are plastics composed of polymers. Most polymers can be broken down into discrete components, which are the building blocks of the polymer; these single units are monomers. The monomer unit of polyethylene is ethylene, while the monomer unit of polypropylene is propylene. The key difference between polyethylene and polypropylene is that polyethylene is produced by polymerizing ethylene monomer units whereas polypropylene is produced by polymerizing propylene monomer units.
