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, mass is calculated as volume multiplied by density after normalizing the units to cubic meters and kilograms. The resulting page multiplier is 0.324126 kg per cup (US).
Use a measured density for a specific batch, grade or supplier; the table value is a reference, not a product specification.
