Basic Knowledge of Plastics: Advantages and Disadvantages of PE

Introducing the benefits of polyethylene, which has high waterproofing properties and particularly excellent mechanical strength at low temperatures!

We will introduce the advantages and disadvantages of 'PE' as basic knowledge of plastics. The advantages include excellent mechanical strength, chemical resistance, and weather resistance, as well as low raw material costs and ease of processing. The disadvantages are that it has low heat resistance, making it vulnerable to fire and heat, and due to its poor adhesion properties, care must be taken when painting or printing. [Advantages] - Low raw material costs and ease of processing - Excellent mechanical strength - Particularly excellent mechanical strength at low temperatures - Excellent chemical resistance - Excellent weather resistance - High waterproofing due to almost no water absorption *For more details, please refer to the PDF document or feel free to contact us.

Basic Knowledge of Plastics: What is PE?

Polymerize ethylene! It can be classified based on manufacturing methods and differences in density.

We will introduce "PE" as a basic knowledge of plastics. "PE" stands for polyethylene, which is obtained by polymerizing ethylene and has a "simple" structure among polymers. It is "produced in large quantities" among plastics. Furthermore, even though the composition is the same "PE," the properties can vary greatly due to structural differences, allowing for classification into several types based on manufacturing methods and density. [Typical Classifications] ■ Low-Density Polyethylene (LDPE) ■ High-Density Polyethylene (HDPE) ■ Ultra-High Molecular Weight Polyethylene (UHPE) *For more details, please refer to the PDF materials or feel free to contact us.

Basic Knowledge of Plastics: Characteristics of PE

Introducing polyethylene, a resin with low water absorption and excellent dimensional stability!

Here is an introduction to the characteristics of "PE" as basic knowledge about plastics. "PE" has a specific gravity of 0.95, making it lightweight. It has low water absorption and excellent dimensional stability. Additionally, it has good chemical resistance and impact resistance. Compared to other synthetic resins, it is a "soft" and "impact-resistant" resin. 【Properties (partial)】 <LDPE> ■ Specific gravity: 0.92 ■ Tensile strength (MPa): 20 ■ Elongation at break (%): 600 ■ Izod impact strength (J/m): does not break *For more details, please refer to the PDF document or feel free to contact us.
