HDPE resin, the full name is high density polyethylene, is a high-density thermoplastic polyolefin produced by copolymerization of ethylene. High density polyethylene resin has better hardness, tensile strength and creep than low-density polyethylene. Meanwhile, it also has the advantages of good wear resistance, electrical insulation, toughness and cold resistance, good chemical stability, low permeability of the film to water vapor and air, as well as low water absorption. At room temperature, HDPE resin is insoluble in any organic solvent and resistant to acid, alkali and various salts.

However, its aging resistance is poor, and its environmental stress cracking resistance is not as good as that of LLDPE resin, especially thermal oxidation will reduce its performance. Therefore, antioxidants and ultraviolet absorbers must be added to the resin to improve this deficiency. High density polyethylene (HDPE) film has a lower heat distortion temperature under stress.

Main Features of HDPE Resin Why Choose Fengbai How Is HDPE Resin Prepared

1. HDPE is a highly crystalline, non-polar thermoplastic resin.

2. The appearance of the original HDPE resin is milky white, and the thin section is translucent to a certain extent.

3. HDPE resin has excellent resistance to most domestic and industrial chemicals.

4.The polymer is non-hygroscopic and has good water vapor resistance for packaging purposes.

5. High density polyethylene (HDPE) has good electrical properties, especially the high dielectric strength of the insulation, making it very suitable for wires and cables.

6. Medium to high molecular weight grades HDPE have excellent impact resistance at room temperature or even down to -40F.

7. The unique properties of the various grades of HDPE are the proper combination of four fundamental variables (density, molecular weight, molecular weight distribution and additives). Different catalysts are used to produce polymers with tailored special properties. These variables combine to produce HDPE grades for different uses, achieving an optimal balance of properties.

8. HDPE recycling. HDPE high density polyethylene is the fastest growing resin in the plastic raw material recycling market. This is mainly due to its ease of reprocessing, minimal degradation characteristics and its wide application in packaging applications.

  • A leading high density polyethylene hdpe resin supplier and exporter in China.
  • Free samples for testing.
  • Stable supply & fast delivery.
  • Various packaging to meet customers’ requirements.
  • ISO quality, good service and competitive prices.
  • Good cooperation with cargo agents and shipping companies.

The production of high density polyethylene (HDPE) mainly uses ethylene as the main raw material, and propylene, 1-butene, and hexene as copolymers. Under the action of a catalyst, the slurry polymerizations or gas phase polymerization process is adopted, and the obtained polymer undergoes processes such as flash evaporation, separation, drying, and granulation to obtain a finished product with uniform particles.

HDPE resin is suitable for various molding processes of thermoplastic molding. The development of new catalysts has contributed to improving the performance of new grades of HDPE. The two most commonly used catalyst classes are Philips’ chromium oxide-based catalysts and titanium compound-alkylaluminum catalysts. HDPE produced by Philips-type catalysts has a medium-broad molecular weight distribution. Titanium-aluminum alkyl catalysts produce narrow molecular weight distributions. Catalysts used in the production of narrow MDW polymers using multiple reactors can also be used to produce broad MDW grades. That is, two reactors in series producing products of significantly different molecular weights can produce bimodal molecular weight polymers with the full breadth of molecular weight distribution.
