Methodology

Plastic (PET) density and calculation basis

Evidence status: needs-review.

PET density depends on grade and material structure.

grade: TECADUR PET natural, unfilled/unmodified stock shape

Source basis: Ensinger, TECADUR PET natural. Technical details: density. https://www.ensingerplastics.com/en-gb/shapes/polyester-tecadur-pet-natural Applicability: conditional-comparison.

Resolve grade and crystallinity before judging 1370 versus 1390 kg/m³.

Temperature not stated.

For this direction, volume is calculated as mass divided by density after normalizing the units to kilograms and cubic meters. The resulting page multiplier is 0.331089 L per lb.

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