Mpempe karama ihe ọṅụṅụ Carbonated PET resin
Okwu Mmalite ngwaahịa
Mpempe akwụkwọ polyester na-aṅụ ihe ọṅụṅụ carbonated bụ polyetylene terephthalic copolymer dabere na TPA.Ọ bụ polymer arọ molekụla dị elu maka ojiji n'ozuzu n'ichepụta arịa.Enwere ike iji ya na-emepụta karama mkpọ maka ihe ọṅụṅụ dị nro nke carbonated dị ka kola na 3-galọn, nnukwu karama 5-galọn.
