Main Characteristics of Sinopec YGH041T
- Density. Its density is about 0.949g/cm³, and the high density makes it have good rigidity, can withstand greater pressure and load, and is not easy to deform under heavy pressure, providing a solid structural foundation for applications such as pressure pipes.
- Melt flow rate. Under the test conditions of 190℃ and 5kg, the melt flow rate (MFR) is about 0.4g/10min. The moderate melt flow rate makes the material have good fluidity during processing. In extrusion, injection molding and other processing processes, it can smoothly fill the mold cavity to form various complex shapes of products, while ensuring the quality of the products and avoiding defects due to fluidity problems.
- Molecular structure and performance correlation. Its molecular structure is unique, which gives the material good comprehensive performance. HDPE YGH041T has a good balance of rigidity and toughness. When subjected to pressure and external force impact, it can maintain a stable structure and is not easy to break or deform.
- Hardness. The Shore hardness reaches 56, indicating that the material has good wear resistance and scratch resistance. In actual use, Sinopec YGH041T can effectively resist external mechanical damage, maintain the integrity of the material surface, and extend the actual service life of the material.
- Good thermal stability. The thermal stability time (EN 728 test) can reach 15min. Within a certain temperature range, the material can maintain the stability of its shape and performance. At the same time, the brittle temperature (ASTM D-746 test) is lower than -70℃, which has good cold resistance and can be used normally in low temperature environments, broadening its application temperature range.
- Environmental stress cracking resistance. The environmental stress cracking resistance time (ASTM D-1693-A test) is greater than 10000h. This excellent performance makes the material less likely to crack under complex environmental conditions, even if it is affected by the combined influence of external stress and environmental factors, which greatly improves the reliability and service life of the material.
- Mechanical properties. The elongation at break (ISO/DIS6259 test) is greater than 600%, and the tensile yield stress (ISO/DIS6259 test) is 23MPa. A higher elongation at break means that the material has better flexibility and ductility, and can produce a large deformation without breaking when subjected to tensile force; and the appropriate tensile yield stress ensures that the material will not easily yield under a certain external force, maintaining structural stability. The simply supported beam impact strength is not damaged at 23℃ (ISO 79 – LeU test), showing good toughness, can effectively resist impact loads, avoid rupture due to impact, and ensure the safe use of the material under different working conditions.
Production Process
HDPE YGH041T is produced using the advanced Borstar technology of Borealis. This technology can accurately control the polymerization process and precisely regulate key indicators such as molecular weight distribution, content and distribution of comonomers. Through ingenious control, a unique molecular structure is formed, which combines the excellent mechanical properties given by the high molecular weight part and the excellent processing performance brought by the low molecular weight part, laying a solid foundation for the excellent performance of the product in practical applications.
