Polyethylene CAS#9002-88-4
The low moisture absorption of our polyethylene resins, together with excellent dimensional stability, reliable flow properties, and a wide processing range, promotes even wall thickness in blow-moulded containers, accurate reproduction of intricate shapes in injection-moulded parts, and uniform thickness control in blown and cast films, helping reduce material consumption and improve overall production efficiency.
