Polyethylene mai nauyin ƙwayoyin halitta mai matuƙar girma (UHMW-PE) yana nufin polyethylene mai layi tare da matsakaicin nauyin ƙwayoyin halitta sama da miliyan 1.5. Saboda girman nauyin ƙwayoyin halitta mai yawa (polyethylene na yau da kullun yana tsakanin 20,000 zuwa 300,000, UHMW-PE yana da cikakken aiki mara misaltuwa idan aka kwatanta da polyethylene na yau da kullun da sauran robobi na injiniya:

1) Juriyar lalacewa mai matuƙar ƙarfi, sau 4 ya fi nailan 66 da PTFE, sau 6 ya fi ƙarfen carbon, mafi kyau a cikin dukkan resins na roba a halin yanzu.

2) Ƙarfin tasirin yana da girma sosai, wanda ya ninka na polycarbonate sau biyu da kuma na ABS sau biyar, kuma yana iya kiyaye ƙarfi mai yawa a zafin jiki na ruwa na nitrogen (-196 ℃).

3) Kyakkyawan kayan shafawa mai laushi, kayan shafawa mai laushi daidai yake da na PTFE, kuma ma'aunin gogayya shine 0.07-0.11 kawai; 1/4-1/3 ne kawai na ma'aunin gogayya na ƙarfe.

4) Darajar shan kuzarin girgiza ita ce mafi girma a cikin dukkan robobi, kuma tasirin rage hayaniya yana da kyau sosai.

5) Yana da ƙarfin sinadarai mai yawa kuma yana iya jure wa cututtuka daban-daban da kuma ƙwayoyin halitta a cikin wani yanayi na zafin jiki da yawan aiki.

6) Ƙarfin hana mannewa, wanda ya fi "Plastic King" PTFE.

7) Cikakken tsafta ne kuma ba shi da guba, ana iya amfani da shi wajen hulɗa da abinci da magunguna.

8) Yawan shine mafi ƙanƙanta a cikin dukkan robobi na injiniya, kashi 56% ya fi PTFE sauƙi da kashi 22% ya fi polycarbonate sauƙi; yawan shine kashi 1/8 na ƙarfe, da sauransu.

Saboda kyakkyawan aikin da aka ambata a sama, ana kiran UHMW-PE da "roba mai ban mamaki" a ƙasashen Turai da Amurka kuma an yi amfani da shi sosai a masana'antu da yawa.
