Polytetrafluoroethylene (PTFE)
●Tsarin: Ya ƙunshi sarkar zarra ta carbon da zarra mai fulorine wanda ya cika (-CF)₂- CF₂-), kuma shi ne fluoropolymer.
●Fasaloli: Ƙarfin ƙarfe mai ƙarfi na carbon-fluorine yana ba shi babban rashin ƙarfi na sinadarai da juriya na yanayi.
Polyester
●Tsarin: Babban sarkar ya ƙunshi ƙungiyar ester (-COO-), kamar PET (polyethylene terephthalate) da PBT (polybutylene terephthalate).
●Features: Haɗin ester yana ba shi ƙarfin injina mai kyau da aiki, amma kwanciyar hankalin sinadarai ya yi ƙasa da na PTFE.
