Comparison Analysis of HDPE and LDPE
Analysis of material structure and material properties, as well as discussions on defects and degradation phenomena using various analytical methods.
There are two main types of polyethylene resin: high-density polyethylene (HDPE) and low-density polyethylene (LDPE). While the basic molecular structure of each is the same, the differences in the number of branching structures and other factors result in different properties as polymers. Here, we present examples comparing HDPE and LDPE from various analyses. Our company not only analyzes material structures and properties but also examines variations in process conditions, defects, and degradation phenomena through various analytical methods. [Case Study Content] ■ Comparative analysis of main skeleton using FT-IR ■ Comparative analysis of thermal decomposition temperature using EGA-MS ■ Comparative analysis of thermal decomposition products using thermal decomposition GC-MS *For more details, please refer to the PDF document or feel free to contact us.
basic information
【Characteristics of HDPE and LDPE】 ■ High-Density Polyethylene (HDPE) - Has fewer branched structures - High degree of crystallinity - Low transparency - Excellent mechanical strength, heat resistance, and chemical resistance ■ Low-Density Polyethylene (LDPE) - Has many branched structures - Low degree of crystallinity - High transparency - Soft and excellent processability *For more details, please refer to the PDF document or feel free to contact us.
