Methodology

Plastic (HDPE) density and calculation basis

Evidence status: publishable.

Representative HDPE material density, supported by the FI0750 grade; grades vary.

grade: HDPE FI0750 resin for blown film

Source basis: SABIC, Polymers product portfolio: HDPE blown film. PDF p.3, HDPE blown film: FI0750 row. https://www.sabic.com/en/Images/Polymers-All-Products_tcm1010-42650.pdf Applicability: adopted-context.

Density temperature not stated; melt-flow test temperature must not be reused as density temperature.

For this direction, mass is calculated as volume multiplied by density after normalizing the units to cubic meters and kilograms. The resulting page multiplier is 3.596141 kg per gal (US).

Use a measured density for a specific batch, grade or supplier; the table value is a reference, not a product specification.
