High-Density Polyethylene (HDPE, PE-100) is a basic thermoplastic polymer used for the production of pipes (water supply, gas supply, sewage), blow-molded products (jerry cans, drums, bottles), films (T-shirt bags, garbage bags), and injection-molded products (crates, pallets, containers). Density 0.941–0.965 g/cm³, tensile strength 22–32 MPa, melting point 125–135°C. Grades: pipe grades (PE-80, PE-100 for pressure pipes, MRS 8–10 MPa), blow molding grades (MFR 0.3–1.0 g/10 min), film grades (MFR 0.03–0.1). GOST 16338-85. Granules, 25 kg bags, big bags. Export documentation: Safety Data Sheet (SDS/MSDS), Certificate of Analysis (CoA), Certificate of Origin. Exports to China, EAEU, Middle East, Southeast Asia.
