What is the difference between PE80 and PE100?
Thread Content
PE material is polyethylene, the most widely used type of plastic material; it is a polymer synthesized from polyethylene. It is basically divided into two categories: low-density polyethylene LDPE (with lower strength) ； High-density polyethylene HDPE. PE materials are classified into five grades according to international standards: PE32, PE40, PE63, PE80, and PE100. The PE pipes used for water supply pipelines are made of high-density polyethylene HDPE, and there are two grades: PE80 and PE100 (based on the abbreviation MRS for Minimum Required Strength). The MRS of PE80 reaches 8 MPa ； The MRS of PE100 reaches 10 MPa. MRS refers to the strength of the tube under circumferential tensile stress (calculated according to international standards).
The original poster has in-depth knowledge of plastic materials, and I am also very interested in learning about the various grades of PVC, PP, PVDF, and PFA.
The grade is mainly determined by the melt index and density
