Kedu ihe bụ PET Polyethylene Terephthalate na CAS 25038-59-9?

PET (polyethylene terephthalate) nwere ike ịnọgide na-enwe ezigbo ihe onwunwe anụ ahụ na nke mekanikal n'ọtụtụ okpomọkụ. PET nwere ezigbo ike ọgwụgwụ, iguzogide esemokwu, ezigbo ike ịka nká, na mkpuchi eletriki pụrụ iche. PET kwụsiri ike nye ọtụtụ ihe mgbaze organic na asịd inorganic, nwere obere ike mmepụta na ezigbo nhazi. Ya mere, ejirila PET mee ihe nke ukwuu na karama nkwakọ ngwaahịa plastik, ihe nkiri na eriri sịntetik.
