ETFE (ma ọ bụ Ethylene tetraflurorethylene) bụ rọba nke dabeere na fluorine, nke nwere ebe mgbaze dị elu yana ezigbo kemịkalụ, eletriki na ike dị elu na-eguzogide ọgwụ.PTFE (ma ọ bụ polytetrafluroethylene) bụ fluorocarbon siri ike.Na-arụ ọrụ dị ka hydrophobic, ọ bụghị mmiri ma ọ bụ ihe ndị dabeere na mmiri na-eme mmiri PTFE.PTFE ebelata esemokwu, eyi ya mere ike oriri nke nfuli dị ka o nwere otu n'ime ndị kasị ala ọnụọgụ nke esemokwu megide ihe ọ bụla siri ike.
Ihe ndị a na-ejikarị eme ihe iji megharịa mgbapụta bụ PTFE na ETFE polymers.
A na-ewu PTFE site na carbon na fluorine atom ebe ETFE sitere na carbon, fluorine na hydrogen.Inye uru na iji ma.
Ike ike nke ETFE nwere ike ịdị ihe dị ka 38% karịa PTFE, nke pụtara na ihe ETFE nwere ike idowe ọnọdụ ọrụ siri ike karịa onye ibe ya.
Nke a bụ ya mere a na-enye ọtụtụ nfuli kemịkal na ETFE ka ọ bụ ihe siri ike maka usoro ịkpụzi injection nke ha na-agafe.
Otú ọ dị PTFE nwere ọnụọgụ nke esemokwu na otu ụzọ n'ụzọ atọ nke ETFE na-eme ka ọ dịkwuo mma mgbe ọ dị mkpa ka ọ dị mkpa ka ọ na-enyere aka belata esemokwu ọkpọkọ Losses. Thermal Njirimara nke ma ihe bụkwa isi ihe dị iche iche ... PTFE nwere ike iru oke okpomọkụ nke 327c. ebe ETFE nwere ike iru oke okpomọkụ nke 267c.

Ọzọkwa, PTFE nwere njedebe Oxygen Index (opekempe pasent oxygen nke polymer ga-ere ọkụ) karịa 95% ebe ETFE dị n'etiti 30-36%, nke pụtara na PTFE kwesịrị ịtụle na gburugburu ikuku oxygen.
