The hardness of polyethylene sheet has a wide range, mainly depending on its type and manufacturing process.
The hardness of polyethylene sheet (PE) ranges roughly from 20 to 90, depending on its type and manufacturing process. Soft polyethylene has a lower hardness, usually between 20 and 45 Shore hardness (HRC), while high-density polyethylene (HDPE) has a higher hardness, which can reach about 90D. In addition, the hardness of polyethylene sheet can also be adjusted by adding plasticizers or other additives to meet different application requirements.
The physical and chemical properties of polyethylene sheet also have a significant impact on its hardness. High-density polyethylene has good heat and cold resistance, good chemical stability, high mechanical strength, good electrical insulation and environmental stress cracking resistance. These characteristics make polyethylene sheet perform well in a variety of applications, especially in situations where high strength and wear resistance are required.
