Industry-standard of PE farmland irrigation pipe

The material of PE farmland irrigation pipe is polyethylene, the most extensive variety of plastic materials. It is a polymer material synthesized from polyethylene. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE farmland irrigation pipes must withstand a certain pressure, and PE resins with large molecular weight and good mechanical properties, such as HDPE resins, are usually selected. This material is basically divided into two categories: low-density polyethylene LDPE (lower strength); high-density polyethylene HDPE. PE materials are divided into five grades according to internationally unified standards: PE32 grade, PE40 grade, PE63 grade, PE80 grade, and PE100 grade.

The high-density polyethylene HDPE used for PE farmland irrigation pipes has two grades: PE80 and PE100 (according to the abbreviation MRS of Minimum Required Strength). The MRS of PE80 reaches 8MPa; the MRS of PE100 reaches 10MPa. MRS refers to the ring tensile stress strength of the pipe (calculated according to the international standard test).

PE80 (8.00~9.99Mpa), is a masterbatch with 80% antimony trioxide content on polyethylene substrate, which can be mainly used in casting and filmmaking. It is a granular free-flowing dust-free masterbatch, which is safer than traditional powder in the production process and easy to control the dosage. It is also considered a general-purpose masterbatch, and the granular form can flow freely.PE100(10.00~11.19Mpa)It is the graded number obtained after rounding the minimum required strength (MRS) of polyethylene raw materials. According to GB/T18252, the hydrostatic strength of the material corresponding to 20°C, 50 years, and a predicted probability of 97.5% is determined.
