Polyethylene 5620EA or material 5620 is a heavy-duty polyethylene (HDPE) with a narrow molecular weight distribution. This grade is suitable for injecting thin-walled parts that require high injection speed and high resistance to deformation.
Heavy polyethylene is between 0.95 and 0.97 grams per cubic centimeter. Heavy polyethylene has a wide variety of applications depending on the molecular weight of the polymer chain.
Lower molecular weight grades are used for the injection process and are used in the production of various injection parts such as kitchen utensils and toys, etc. Higher molecular weight grades are used to produce polymer films and pneumatic containers for packaging.
Higher molecular weight grades are used to produce polyethylene pipes for cold water transport for urban and agricultural purposes.
