Product Overview
PetroChina Jilin HDPE JHMGC100S is a high-molecular-weight bimodal PE100 pipe grade produced by PetroChina Jilin Petrochemical using Hostalen slurry technology and Z501 catalyst. It offers corrosion resistance, strong resistance to environmental stress cracking and rapid crack growth, good fusion welding and good sag resistance in large-diameter pipe.
Grade & Processing
Grade: JHMGC100S. Polymer family: high-density polyethylene (HDPE), PE100 pipe grade. Designed for pipe extrusion, including large-diameter pressure pipe.
Typical Applications
- Pressure-bearing water pipe
- Industrial pipe
- Large-diameter water-supply pipe
- PE100 gas-pipe raw material subject to project approval
