Basic Knowledge of Plastics: Advantages and Disadvantages of PE

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.

Measurement examples of DSC (Differential Scanning Calorimetry)

Measurement examples of DSC (Differential Scanning Calorimetry)

Comparing thermal properties with DSC! We will discuss the impact of type discrimination and the state of polymer molecular chains on material properties!

Polyethylene (PE) comes in several types with different material properties depending on the length and number of its side chain branches. From the melting peak of crystalline polymer polyethylene, we measured the melting point and crystallinity using DSC and compared them by type of polyethylene. LDPE, which has many long side chains and is less dense, resulted in a low melting point and low crystallinity. In contrast, HDPE, which tends to have a denser molecular chain, showed high values for both melting point and crystallinity. Additionally, LLDPE, which has many relatively short side chains and is more likely to be dense than LDPE, exhibited intermediate values for both melting point and crystallinity between LDPE and HDPE. **Types of Polyethylene** - **LDPE (Low-Density Polyethylene):** Low rigidity and high flexibility - **LLDPE (Linear Low-Density Polyethylene):** Stronger than LDPE but inferior processability - **HDPE (High-Density Polyethylene):** High rigidity, excellent tensile strength, impact strength, and hardness *For more details, please refer to the PDF document or feel free to contact us.*

Basic Knowledge of Plastics: What is PE?

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

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.

Polyethylene (PE) Tank Deterioration Diagnosis [Simple Diagnosis]

Polyethylene (PE) Tank Deterioration Diagnosis [Simple Diagnosis]

Scientifically analyze the lifespan of PE tanks that cannot be judged by appearance! Easy diagnosis in 3 steps!

DaiLight's "Polyethylene (PE) Tank Degradation Diagnosis" utilizes FTIR (Fourier Transform Infrared Spectroscopy) to derive a carbonyl index from sampled resin, which determines the progression of oxidative degradation, and reports it on a five-point scale. If you would like to know the degradation status of your polyethylene tank, please feel free to make a request. We handle everything from sales to long-term usage tank degradation diagnosis, disposal of discarded tanks, and installation of replacement tanks. 【Diagnosis Method】 1. Select the tank to be diagnosed. 2. Sample the surface of the tank with a specialized "file." 3. Return the "file" and the "degradation diagnosis request form." *For more details, please download the PDF or contact us.

[Information] Basic Knowledge of Materials - What is Polyethylene?

[Information] Basic Knowledge of Materials - What is Polyethylene?

Introducing basic knowledge about polyethylene materials!

Polyethylene (PE) generally refers to the high polymer of ethylene CH2=CH2. Its main applications are in food and agricultural houses, as well as industrial material films. Additionally, it is used for containers such as milk and juice, processed paper like craft tape, and for electrical wire insulation. For more details, the external link page provides an easy-to-understand explanation of synthetic resin materials. [Excerpt of content] - High polymer of ethylene CH2=CH2 - Synthesized by high-pressure method (1,000–2,000 atmospheres, around 200°C) or low-pressure method (Ziegler catalyst system) - Low-density polyethylene (LDPE) - High-density polyethylene (HDPE) - Used not only for film applications but also for blow molding and injection molding *For more information, please refer to the external link page or feel free to contact us.
