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 1.399433 cup (US) per lb.
Use a measured density for a specific batch, grade or supplier; the table value is a reference, not a product specification.
