Excellent Environmental Stress Cracking Resistance (ESCR): DGDX-6095 exhibits outstanding resistance to stress cracking, effectively preventing pipes and hollow containers from undergoing brittle failure during long-term pressure containment or exposure to chemical media, thereby significantly extending the service life of final components.
High Mechanical Strength and Impact Resistance: Featuring a tensile strength at yield and break of 26 MPa, combined with an astonishing tensile strain at break of 898%, this material delivers exceptional toughness, ensuring that finished products remain resistant to deformation under external compressive forces or ground settlement.
Superb Extrusion Processing and Blow Molding Performance: Under a heavy-load test condition of 21.6 kg, its melt mass-flow rate (MFR) stands at 10.4 g/10min, demonstrating excellent melt strength and processing flowability, making it ideally suited for high-speed extrusion of large-diameter pipes and high-strength hollow blow molding applications.
Outstanding Molecular Weight Distribution and Material Stability: The density is precisely controlled at 0.591 g/cm3, offering an ideal balance between rigidity and flexibility, which enables the finished products to maintain superior dimensional stability across varying ambient temperatures.
Leveraging its combination of high rigidity, superior toughness, and excellent chemical resistance, Dushanzi Petrochemical DGDX-6095 HDPE is extensively utilized throughout major manufacturing industries that demand strict safety and durability parameters:
Municipal & Industrial Piping Systems: Primarily used for the extrusion manufacturing of high-performance gas pipelines, urban water supply networks (PE100 grade pipe raw material), drainage pipes, silicon core conduits, and industrial chemical transmission pipelines.
Large Hollow Blow Molded Containers: Utilized for manufacturing large-capacity plastic drums, chemical liquid packaging barrels (inner liners for Intermediate Bulk Containers – IBC totes), pesticide bottles, and various high-strength hollow industrial containers.
Agricultural Irrigation & Cable Jacketing: Applied in water-saving irrigation drip lines, water micro-conduits, as well as wear-resistant protective outer jackets for telecommunication fiber optic cables and electric power cables.
Q1: Does Dushanzi Petrochemical DGDX-6095 HDPE require pre-molding drying treatment prior to processing?
A1: High-density polyethylene (HDPE) is inherently a non-hygroscopic (hydrophobic) material; therefore, under normal transportation and storage conditions, it typically does not require high-heat drying treatments. However, if the resin is stored for extended periods in humid conditions or warehouses with massive temperature fluctuations, or when it enters a heated processing workshop during winter, physical condensation may develop on the pellet surfaces. To prevent cosmetic bubbles or surface pitting during extrusion or blow molding, it is recommended to inspect the packaging prior to processing and, if necessary, perform a surface moisture removal treatment in a desiccant dryer at 70°C–80°C for 1–2 hours.
Q2: What are the core technical differences between Dushanzi Petrochemical DGDX-6095 and conventional LDPE (Low Density Polyethylene)?
A2: The core differences lie in density, rigidity, and thermal resistance. As an HDPE grade with a density of 0.951 g/cm3, DGDX-6095 features minimal molecular chain branching, resulting in a significantly higher crystallinity level compared to LDPE. This gives it a much higher tensile strength (26 MPa) and hardness than LDPE, alongside superior heat deflection capabilities and chemical permeation resistance. While conventional LDPE is softer and highly flexible, making it ideal for extruded films (such as packaging bags), DGDX-6095 is rigid and tough, engineered specifically for industrial pipes and heavy-duty hollow containers that must endure pressure and mechanical loads.
Q3: Does this grade comply with global environmental certifications for bulk plastic trade, such as RoHS or REACH?
A3: Yes. As a leading petrochemical manufacturer in China, PetroChina Dushanzi Petrochemical ensures that its DGDX-6095 HDPE prime virgin pellets strictly adhere to international environmental compliance standards. The material fully meets the requirements of the European Union RoHS 2.0 and REACH regulations, containing no hazardous heavy metals (such as lead, mercury, cadmium, hexavalent chromium) and no added toxic phthalate plasticizers. It is completely suitable for industrial-safety grade packaging and water supply pipeline construction across all global markets. For inquiries from overseas buyers, we can provide original factory Certificate of Analysis (COA) documents and other technical support files upon request.
