Polyethylene (BL4 (HM-8355 or BL4 material) is a heavy-duty polyethylene with good processability. Up to 500 liters is suitable.
The density of heavy polyethylene is between 0.95 and 0.97 grams per cubic centimeter. Chains of heavy polyethylene molecules have few side branches, so it is possible for the molecular chains to come closer together and form crystals.
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 injectable 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.
