Hengli GC7260 HDPE Resin: High-Flow and High-Stiffness Grade for Bottle Caps & Daily Injection Molded Products
Hengli GC7260 is a common HDPE material for injection molding. It is made by Hengli Petrochemical. This homopolymer grade has good melt flow and strong hardness. It keeps products in stable size, and it is safe to touch food. It works well on fast injection machines. It can make molding time shorter, and cut down product faults. People use this plastic widely. It makes packaging goods, daily items, medical parts and common industrial plastic pieces. It is also a good material for bottle caps and thin-wall plastic products.
1. Basic Product Specifications
All data are typical values for reference. This is new pure plastic. It looks like even milky white small pellets. It has almost no dirt or black spots, so quality stays the same across different batches. Each bag weighs 25 kg, and all goods use original factory packages. We give a quality test report for every batch, so you can check product quality fully.
Density: 0.960 g/cm³
Melt Flow Rate (MFR): 8.0 g/10min (190 °C/2.16kg, typical range: 8.0–8.2 g/10min)
Tensile Yield Strength: ≥26 MPa
Flexural Modulus: 1350 MPa
Small shrinkage during molding, and products keep steady size
2. Core Product Advantages
Good melt flow for fast filling and high-speed work
This plastic flows easily when melted. It fills molds quickly. You can make thin and complex plastic parts smoothly. It makes each injection cycle shorter, so production runs faster. It fits most common injection molding machines.
Strong hardness and less bending for accurate size
This material is hard enough. Finished products stay firm and do not change shape easily. It shrinks a little during molding, so products will not bend, deform or have wrong sizes. It meets the standard for precise plastic parts.
Food-safe and pure, no substance leakage
The pellets are pure. They have no strange smell, and no material will leak out. It follows local rules for food contact. You can use it directly to make products that touch food. It meets strict health rules for food packages and food containers.
Resist chemicals well and keep stable physical performance
It can stand acid, alkali and common daily chemicals. It also stays tough in low temperature. Products made from it do not crack or turn bad after long use. You can use these plastic goods indoors and outdoors.
3. Detailed Application Fields
Food Packaging：Water bottle caps, drink bottle caps, thin fresh-keeping boxes, yogurt cups, sauce and seasoning containers
Daily Chemical Packaging：Caps for cosmetic and detergent bottles, pump heads for lotions, parts of cosmetic tubes, hard parts for laundry detergent bottles
Daily Plastic Products：Plastic tables and chairs, storage boxes, trash cans, basins, plastic hangers, plastic parts for toys
Medical and Sanitary Products：Syringe push rods, medical bottles, medical disinfection boxes, toothbrush handles, disposable mouthwash cups
General Industrial Injection Parts：Plastic parts for car interiors, shells for home appliances, plastic battery boxes, electric junction boxes
We can change this material to be anti-static, weather-proof or tougher if you need.
4. Injection Processing Guidelines
Recommended Process Parameters
Barrel temperature: 180–220 °C. Raise the temperature step by step from material inlet to nozzle.
Mold temperature: 30–60 °C. Low temperature stops bending; high temperature makes product surface smoother.
Injection pressure: 80–120 MPa
Drying: You do not need to dry it under normal storage. If pellets get wet, dry them at 60–70 °C for 1 hour.
Blending: You can mix it with LDPE, LLDPE or PP. The mix makes products tougher and cuts production cost.
5. Quality Assurance & Procurement Support
