So PP ye sen PET sɛ akwanside a ɛma nsu ntumi nkɔ mu? Data si so dua: yiw, PP ma nsu akwanside adwumayɛ a ɛkorɔn.

Nanso, akwanside mfonini no yɛ nea ɛyɛ nuanced kɛse: PET di mu sɛ oxygen akwanside, na ne dwumadi ye sen PP bɛyɛ mpɛn 23.

Wɔ strapping dwumadie mu no, mpɛn pii no ɛnyɛ nsuo akwansideɛ nyɛ ade titire a wɔpaw, nanso PP awosu mu nsuo a ɛko tia —a ɛfiri ne hydrocarbon nhyehyɛeɛ a ɛnyɛ polar mu —ma ɛfata ma abɔnten so nneɛma a wɔkora so, kuayɛ, ne nsuo a atwa yɛn ho ahyia a wɔde di dwuma.
