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.*

Observe the degree of endothermic/exothermic reaction of the sample! The temperature range can go from -90°C to 550°C.

DSC (Differential Scanning Calorimetry) is an analytical method that determines the heat difference based on the temperature difference between the sample and a reference material caused by temperature changes in the sample, allowing for the observation of the degree of endothermic/exothermic reactions of the sample. The temperature range is -90°C to 550°C, the required sample amount is 5 to 10 mg, and the sample shapes that can be measured include film, powder, and bulk. 【Features】 ■ Differential Scanning Calorimetry ■ Observation of the degree of endothermic/exothermic reactions of the sample ■ Temperature range: -90°C to 550°C ■ Required sample amount: 5 to 10 mg ■ Sample shapes: film, powder, bulk *For more details, please refer to the PDF document or feel free to contact us.

We have introduced our Majesta Fragrance in the restrooms of a company located in the city. The model we implemented is the compact-sized MFmini. By adding fragrance to the clean space, we have created an environment where users can spend their time more comfortably. The restroom, which is used daily, has become a more pleasant and high-quality space.

Thank you very much for always using Majesta Fragrance. Our company will be open as usual during the Obon period. Please feel free to contact us for inquiries about scent arrangements or the introduction of commercial aroma diffusers.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
