Polyethylene Properties Explained: The Complete Guide for Industrial Buyers Understanding the core properties of polyethylene is critical for sourcing cost-effective, high-performance materials that meet your manufacturing specifications and reduce project
Understanding the core properties of polyethylene is critical for sourcing cost-effective, high-performance materials that meet your manufacturing specifications and reduce project costs.
Get Your Free Material Specification Sheet in 24hAs a purchasing manager or technical director, specifying the wrong polyethylene grade can have severe financial and operational consequences. Are you facing these challenges?
These issues stem from a gap between generic material data sheets and your specific application needs. The solution is a supplier who bridges that gap with technical expertise and transparent pricing.
View Our Detailed Polyethylene Property Tables →At HEBEI XIONGYI, we leverage our deep manufacturing expertise to help you select the precise polyethylene grade based on a clear understanding of its properties of polyethylene. Here’s how our approach delivers value.
Use this table to compare key properties of polyethylene plastic across common grades. This is a guideline; we provide precise data for each order.
| Property | LDPE (Low-Density) | LLDPE (Linear Low-Density) | HDPE (High-Density) |
|---|---|---|---|
| Density (g/cm³) | 0.910-0.925 | 0.915-0.925 | 0.941-0.965 |
| Tensile Strength (MPa) | Low (7-17) | Medium (20-30) | High (25-40) |
| Impact Resistance | Good | Excellent | Good to Very Good |
| Chemical Resistance | Excellent | Excellent | Excellent |
| Max. Continuous Use Temp (°C) | 80 | 90 | 120 |
| Typical Applications | Flexible films, bags, coatings | Stretch film, liners, geomembranes | Containers, pipes, fuel tanks |
polyethylene structure polyethylene molecular structure what is polyethylene
For Packaging Managers: Need clarity and tear resistance? We recommend specific LLDPE grades with high dart impact strength for heavy-duty sacks.
For Injection Molders: Require high flow and fast cycle times? Our HDPE resins with optimized Melt Flow Index (MFI) reduce warpage and improve production efficiency.
For Wire & Cable Manufacturers: Our cross-linkable polyethylene (XLPE) compounds offer superior dielectric strength and long-term thermal stability for insulation.
Describe Your Application for a Custom Recommendation →A: For structural applications, focus on tensile strength, flexural modulus, and environmental stress crack resistance (ESCR). HDPE typically offers the best balance. We provide detailed data sheets and can recommend grades with enhanced ESCR for long-term durability.
A: Absolutely. As an OEM/ODM manufacturer, we routinely compound color masterbatches and UV inhibitors directly into the resin. This is more cost-effective and consistent than post-processing. Specify your Pantone code and required UV exposure hours (e.g., 1500 hrs ASTM G154).
A: For standard grades, lead time is 15-25 days after order confirmation. We accept T/T, LC at sight. Standard packing is 25kg/bag on 1-ton pallets, 20-24 MT per 40'HQ container. FOB Tianjin/CQF is most common, with CIF quotes available for major ports.
A: Consistency is critical. We source prime polymers from major refineries and conduct in-house QC on key properties of polyethylene like MFI and density. You receive a Mill Test Report with each batch, and we retain samples for traceability.
A: Yes. We provide free 2-5kg samples of our standard or customized compounds for your lab testing and trial runs. You only pay for the international courier freight. This allows you to verify properties like chemical resistance and processability risk-free.
"We switched to XY Grass for our HDPE pipe compound 18 months ago. The ESCR property data was accurate, and the material has performed flawlessly in the field. Their technical support helped us optimize our extrusion parameters, reducing our scrap rate by 12%."
– Michael R., Procurement Director, A Midwest-based Plumbing Systems Manufacturer
"As a custom molder, we need reliable flow properties. XIONGYI's consistent MFI has minimized our cycle time variations. Their pricing is transparent with no hidden fees, which is rare. Sourcing directly from their factory has cut our material costs by 22% versus domestic distributors."
– Sarah L., Operations Manager, An Industrial Component Supplier (California, USA)
"The UV-stabilized LLDPE film grade they formulated for our agricultural cover product has exceeded our 3-year durability benchmark. The OEM design process was smooth, and they handled all the compliance documentation for our market."
– David K., Technical Lead, A Specialty Packaging Firm in Texas
