1. Low iguzogide ọnwụ
2.Highly akwa na-eguzogide
3.Anti-clogging, mgbochi backflow
4.Ageing-eguzogide, mgbochi corrosion
5.High arụmọrụ, ike-azọpụta
6.Long ọrụ ndụ, ala maintance
7.Compact Ọdịdị, nkwado siri ike

Na-adịghị ike n'ime mmiri na ihe mgbaze ọ bụla, nke na-adịghị egbu egbu na nke na-enweghị ụtọ, ihe ndị na-emepụta kemịkal kwụsiri ike, ma e wezụga alkali siri ike, hydrofluoric acid anaghị emeghachi omume na ihe ọ bụla.
3.PTFE
①Elu na ala okpomọkụ na-eguzogide, na-arụ ọrụ okpomọkụ nwere ike ịbụ 250ºC, ezi n'ibu siri ike; ọbụlagodi na okpomọkụ dara na -196ºC nwekwara ike idobe 5% elongation.
② Corrosion - iguzogide ọtụtụ kemịkalụ na ihe mgbaze, na-egosi inertia, nguzogide acid siri ike, mmiri na ihe mgbaze organic dị iche iche.
③ High lubrication - ọnụ ọgụgụ esemokwu kacha ala na ihe siri ike.
④ Non-adhesion - bụ obere esemokwu elu na ihe siri ike ma ọ dịghị agbaso ihe ọ bụla.
