Synthetic Route
| According to the polymerization method, low-density polyethylene can be divided into the high-pressure method and low-pressure method. According to the type of reactor, it can be divided into the kettle method and the tube method. Using ethylene as raw material, it is fed into the reactor, and the polymerization reaction is carried out by high-pressure compression under the action of the initiator. The material coming out of the reactor, after the unreacted ethylene is removed by the separator, it is melted, extruded, granulated, dried, blended, and sent for packaging. |
