Description
High-density polyethylene resin is mainly used in the production of film grades, pipe grades, blow molding grades (large and small hollow), injection molding grades and monofilament grades. This product consists of 100% virgin material and contains no recycled material. This dataset includes the main raw and auxiliary materials (monomer, comonomer, catalyst) and energy consumption of the production process, while infrastructure such as the manufacture of production equipment and plant construction is not included within the dataset boundary; the inventory is taken from literature based on actual enterprise survey data; the production process of this high-density polyethylene resin product is the slurry process.
Activity Description
The production process of this high-density polyethylene resin product is a slurry method. The slurry method is to fuse an aliphatic hydrocarbon solvent and ethylene to generate a polymer under the action of a catalyst, and the polymer is suspended in the solvent.
Process Description
High-density polyethylene resin is a fossil plastic product, non-biodegradable, a thermoplastic material, and is a white powder or granular product. This product is composed of 100% virgin materials and contains no recycled materials. High-density polyethylene usually has five major applications: film materials, pipe materials, blown plastics (large hollow and small hollow), injection plastics and monofilament materials.

Technology comment
There are three main production processes for high-density polyethylene: the solution process, the slurry process, and the gas-phase process. Among them, the slurry process and the gas-phase process feature lower reaction pressures, easier control of operating conditions, and better product performance. They have now become the most important production technologies for high-density polyethylene in China. Due to the long process flow, high energy consumption, and high investment associated with the solution process, almost no enterprises in China choose this method for polyethylene production. The slurry process involves combining an aliphatic hydrocarbon solvent with ethylene to generate a polymer under the action of a catalyst, with the polymer suspended in the solvent.
