Thermoforming Petg Sheet Roll China Manufacturer Supplier

PETG material is a kind of transparent plastic in brief, it is an amorphous copolyester. The commonly used comonomer of PETG is 1,4-cyclohexane dimethanol (CHDM), the full name is polyethylene terephthalate. Alcohol ester-1,4-cyclohexanedimethanol ester. It is a polycondensation product of terephthalic acid (TPA), ethylene glycol (EG) and 1,4-cyclohexanedimethanol (CHDM) by the transesterification method, which is 1,4 more than PET -Cyclohexane dimethanol comonomer has more ethylene glycol comonomer than PCT. Therefore, the performance of PETG is quite different from PET and PCT. With its uniqueness, there are only two companies in the world, Eastman of the United States and SK of South Korea, with relatively mature technologies.

An amorphous copolyester. With the increase of CHDM in the copolymer, the melting point decreases, the glass transition temperature increases, and the crystallinity decreases, and finally an amorphous polymer is formed. Generally, the content of CHDM in PETG is 30%-40%. It has good viscosity, transparency, color, chemical resistance, and resistance to stress whitening. It can be thermoformed or extrusion blow molded very quickly. The viscosity is better than acrylic (acrylic). Its products are highly transparent and excellent in impact resistance. It is especially suitable for forming thick-walled transparent products. Its processing and forming performance is excellent. It can be designed in any shape according to the designer’s intention. It can use traditional extrusion, injection molding, blow molding and suction. Molding methods such as plastics can be widely used in the market of sheet materials, high-performance shrink films, bottles and profiled materials. At the same time, it has excellent secondary processing performance and can be modified by conventional machining. PETG is an amorphous copolyester.
