TABLE 1.36 POLYETHYLENE TEREPHTHALATE-BASED COPOLYESTER-EASTMAN CHEMICAL PRODUCTS 

The results of these tests showed that KODAR PETG Copolyester 6763 is resistant to a variety of chemicals, high-molecular-weight esters, aliphatic hydrocarbons, and dilute solutions of acids and salts. PETG 6763 was significantly affected by concentrated acetic acid, acetone, benzene, toluene, carbon tetrachloride, dimethyl formamide, and phenol and was completely deteriorated by concentrated nitric and sulfuric acids and by ethylene dichloride.
