Bimodal linear low-density polyethylene

Bimodal Linear Low Density Polyethylene (LLDPE)

  1. Product Overview

PE is one of the most important general-purpose plastics. Due to different process routes and conditions, the molecular structure (branching degree), molecular weight, density, and crystallinity of the produced PE are different, leading to different physical properties and application ranges.

Bimodal PE is a polyethylene resin with a bimodal molecular weight distribution curve. Compared with

ordinary PE, bimodal PE has both excellent physical and mechanical properties and superior processing performance. The high molecular weight part ensures its physical and mechanical strength, while the low molecular weight part acts as a lubricant in the resin to improve the processability of the product.
