Heavy polyethylene – HDPE
Heavy polyethylene
High density polyethylene or so-called heavy polyethylene have branched polymer chains. Due to the branchless nature of the chain, the intermolecular force in the high chain and its tensile strength is much higher than other types of PE. One of the effective factors in producing this type is the reaction conditions and the type of catalyst, which is usually produced by polymerization method with Ziegler-Nata catalyst.
The price of HDPE type polyethylene materials is not much different from other polyethylene and heavy injection granules.
One of the major producers of heavy polyethylene in Iran is Amirkabir Petrochemical Company, whose heavy polyethylene unit was launched in the Mahshahr Special Economic Zone in 2002.
The production capacity of Amirkabir Petrochemical HD heavy polyethylene unit is 140,000 tons and the products of this unit include about 18 different grades, which are: EX1, CRP100N, CRP100B, EX2, EX3, EX4, EX5, BL2, BL3, BL4, BL5, BL6, BL7, BL8, I1, I2, I3 and I4.
During the last year, the largest amount of production and export of heavy polyethylene was EX3, which is a pipe grade.
