Hehehe...salah ek...tp aku google jumpa ni..
"The resulting chemical, a monomer (single, non-repeating molecule) alcohol, is combined with terephthalic acid and raised to a temperature of 472癋 (280癈). Newly-formed polyester, which is clear and molten, is extruded through a slot to form long ribbons. " Originally posted by musang_pulut at 26-2-2007 09:53 PM
