Core HDPE Specifications: Density, MFI, and Mechanical Properties Explained

When buyers search for HDPE plastic granules on Alibaba.com, they evaluate suppliers based on specific technical parameters. Understanding these specifications is critical for Southeast Asian exporters to communicate product capabilities accurately and match buyer requirements effectively.

Density is the fundamental characteristic that distinguishes HDPE from other polyethylene variants. The industry-standard density range for HDPE is 0.941 to 0.965 g/cm³ (some sources extend to 0.97 g/cm³). This relatively high density compared to LDPE (0.910-0.940 g/cm³) or LLDPE contributes to HDPE's superior strength-to-density ratio, making it ideal for applications requiring structural integrity.

Key Mechanical Properties: Tensile strength ranges from 26-33 MPa, melting point between 120-135°C, and continuous service temperature from -50°C to 80°C. Water absorption is exceptionally low at <0.01%, contributing to HDPE's excellent chemical resistance.

Melt Flow Index (MFI), also known as Melt Flow Rate (MFR), is perhaps the most critical specification for buyers to match their processing equipment and application requirements. MFI measures the flow rate of molten polymer under standardized conditions (typically 190°C with 2.16 kg load for HDPE). Lower MFI values indicate higher molecular weight and viscosity, while higher MFI values indicate easier flow during processing.

HDPE MFI Grade Classification and Applications

MFI Range (g/10min)	Grade Classification	Processing Method	Typical Applications	Buyer Profile
0.2 - 0.6	Very Low Flow (High MW)	Extrusion, Pipe production	Pressure pipes, Gas distribution, Large diameter pipes	Infrastructure contractors, Utility companies
0.8 - 2.0	Low to Medium Flow	Blow molding, Sheet extrusion	Bottles, drums, industrial containers, sheets	Packaging manufacturers, Chemical container producers
3.0 - 10.0	Medium to High Flow	Injection molding	Caps, closures, household items, automotive parts	Consumer goods manufacturers, Automotive suppliers
10.0 - 20.0+	High Flow (Low MW)	Thin-wall injection molding	Thin-wall containers, closures, small parts	High-volume consumer product manufacturers
20.0+	Very High Flow	Specialized injection molding	Thin-wall applications, high-speed production	Mass production facilities, Packaging companies

MFI values measured at 190°C/2.16kg per ASTM D1238. Actual processing recommendations may vary by equipment and specific resin formulation.

Melting Point and Processing Temperature are often confused but represent distinct parameters. The actual melting point of HDPE ranges from 120-135°C, representing the temperature at which crystalline structures break down. However, processing temperatures for injection molding typically range from 180-230°C, while extrusion may require 200-260°C. This distinction is critical for buyers to set appropriate equipment parameters and avoid material degradation.

The Vicat softening point is often confused with melting point, but they measure different properties. Vicat indicates when the material begins to soften under load, while melting point (measured by DSC per ASTM D3418) indicates complete crystalline breakdown. For HDPE, expect Vicat around 120-125°C and melting point around 130-135°C. ^[5]
