I-fiber ye-polyethylene enobunzima be-molecular ephezulu kakhulu (UHMWPE), eyaziwa ngokuba yi-fiber ye-PE enamandla aphezulu, yenye yeefayibha ezintathu zobugcisa obuphezulu kwihlabathi lanamhlanje (i-carbon fiber, i-aramid fiber, kunye ne-polyethylene enobunzima be-molecular ephezulu kakhulu), kwaye ikwayeyona fayibha inzima kakhulu ehlabathini. Ilula njengephepha kwaye iqine njengentsimbi, inamandla aphindwe ka-15 kunentsimbi, kwaye iphindwe kabini kune-carbon fiber kunye ne-aramid 1414 (Kevlar fiber). Okwangoku sesona sixhobo siphambili sokwenza iivesti ezikhusela iimbumbulu.
Ubunzima bayo beemolekyuli buqala kwi-1.5 yezigidi ukuya kwi-8 yezigidi, nto leyo ephindaphinda kaninzi kuneefayibha eziqhelekileyo, nto leyo ekwayimvelaphi yegama layo, kwaye isebenza kakuhle kakhulu.

1. Isakhiwo sixinene kwaye asinayo ikhemikhali enamandla, kwaye izisombululo ezinamandla ze-asidi kunye nezinyibilikisi ze-organic azinampembelelo kumandla aso.
2. Ubuninzi buyi-0.97 grams kuphela nge-cubic centimeter nganye, kwaye ingadada phezu kwamanzi.
3. Izinga lokufunxwa kwamanzi liphantsi kakhulu, kwaye ngokubanzi akufuneki ukuba kome ngaphambi kokuba kwenziwe kwaye kusetyenzwe.
4. Inokumelana okuhle kakhulu nokuguga kwemozulu kunye nokumelana ne-UV. Emva kweeyure ezili-1500 zokuchatshazelwa lilanga, izinga lokugcina amandla efayibha lisafikelela kwi-80%.
5. Inempembelelo entle yokukhusela kwimitha kwaye ingasetyenziswa njengepleyiti yokukhusela kwizityalo zamandla enyukliya.
6. Ukumelana nobushushu obuphantsi, isenamandla okubamba ubushushu kubushushu be-helium engamanzi (-269 ℃), ngelixa imicu ye-aramid ilahlekelwa kukusebenza kwayo okungenakuchaphazelwa ziimbumbulu kwi--30 ℃; Ingagcina amandla amahle kakhulu kwi-nitrogen engamanzi (-195 ℃), uphawu olungenalo ezinye iiplastiki, kwaye ngenxa yoko ingasetyenziswa njengezinto ezimelana nobushushu obuphantsi kushishino lwenyukliya.
7. Ukumelana nokuguguleka, ukumelana nokugoba, kunye nokusebenza kokudinwa okuxineneyo kweefayibha zepolyethylene ezinobunzima obuphezulu kakhulu nazo zinamandla phakathi kweefayibha ezisebenzayo kakhulu ezikhoyo, ezinokumelana okubalaseleyo kunye nokuqina kokusika. Ifayibha yepolyethylene enobunzima obuphezulu kakhulu obuyikota kuphela yobukhulu beenwele kunzima ukuyisika ngesikere. Ilaphu elicutshungulwayo kufuneka lisikwe kusetyenziswa umatshini okhethekileyo.
8. I-UHMWPE ikwasebenza kakuhle kakhulu ekugqumeni umbane.
9. Icocekile kwaye ayinabungozi, ingasetyenziselwa ukunxibelelana nokutya kunye namayeza. Xa kuthelekiswa nezinye iiplastiki zobunjineli, iifayibha ze-polyethylene ezinobunzima obuphezulu kakhulu zineziphene ezifana nokumelana nobushushu obuphantsi, ukuqina, kunye nobunzima, kodwa zinokuphuculwa ngeendlela ezifana nokuzalisa kunye nokudibanisa; Ngokwembono yokumelana nobushushu, iqondo lokunyibilika kwe-UHMWPE (136 ℃) ngokubanzi lifana nele-polyethylene eqhelekileyo, kodwa ngenxa yobunzima bayo obukhulu be-molecular kunye ne-viscosity ephezulu yokunyibilika, kunzima ukuyicubungula.
