Introduction of MDPE Medium-Density Polyethylene (MDPE) is a versatile, semi-flexible polymer known for its unique balance of properties. Its intermediate density, situated between high-density polyethylene (HDPE) and low-density polyethylene (LDPE), makes it a preferred choice in water and gas packaging, construction, and piping systems. Combining strength, flexibility, and impact resistance, MDPE addresses diverse industrial needs
