PETG
PETG plastic is a kind of transparent plastic in short, it is an amorphous copolyester. The common comonomer of PETG is
1,4-cyclohexanedimethanol (CHDM), the full name is polyethylene terephthalate. Alcohol ester-1,4-
cyclohexanedimethanol ester. PETG is an amorphous copolyester. With the increase of CHDM in the copolymer, the
melting point decreases, the glass transition temperature increases, the crystallinity decreases, and finally an amorphous
polymer is formed. Generally, the content of CHDM in PETG is 30%-40%. Has good viscosity, transparency, color,
chemical resistance, and resistance to stress whitening. Quickly thermoformed or extrusion blow molded. Viscosity is
better than acrylic (acrylic). Its products are highly transparent and have excellent impact resistance. It is especially
suitable for forming thick-walled transparent products. Its processing and forming performance is excellent, and it can
be designed in any shape according to the designer's intention. Traditional extrusion, injection molding, blow molding
and suction can be used. Plastic and other molding methods，t can be widely used in the market of sheet material,
high-performance shrink film, bottle and profile material, etc. At the same time, its secondary processing performance is
excellent, and conventional machining can be carried out. PETG is an amorphous copolyester. Its products are highly
transparent and have excellent impact resistance. It is especially suitable for forming thick-walled transparent products.
Traditional molding methods such as extrusion, injection molding, blow molding and blister molding can be widely used
in the market of sheet materials, high-performance shrink films, bottles and profiles, and cosmetic packaging. Regular
machining finishes. The main domestic agents of Eastman PETG and other products currently have Shanghai Lianmo
Chemical Co., Ltd.
