Click:70 Time:2019-07-10 06:00:00

PETG has the same transparency as glass and close to the density of glass, good gloss, chemical corrosion resistance, impact resistance, and easy processing. It can be injection moulding, injection-pull-blow moulding and extrusion-blow moulding. It can also produce unique shape, appearance and special effects, such as bright color, grinding, marble texture, metal luster, etc. Other polyesters, elastic plastics or ABS can also be used for overlapping injection moulding.

Chinese Name: PETG Plastics

English Name: Poly (ethylene terephthalateco-1,4-cylclohexylenedimethylene terephthalate)

Chemical name: polyethylene terephthalate-1,4-cyclohexanedimethyl alcohol ester

PETG is a transparent plastic and amorphous copolyester. The common copolymer unit of PETG is 1,4-cyclohexane dimethyl alcohol ester (CHDM). It is a product of transesterification polycondensation of terephthalic acid (TPA), ethylene glycol (EG) and 1,4-cyclohexanedimethyl alcohol ester (CHDM). Compared with PET, it has more 4-cyclohexanedimethyl alcohol copolymer units. Compared with PCT, it has more polyethylene glycol copolymer units. Therefore, the properties of PETG are quite different from those of PET and PCT. Characteristic.

Good thermoforming performance

Toughness

Weatherability

Simple processing

Good chemical resistance

environmental protection

economical efficiency

There are fewer suppliers of PETG materials in the world.

There are only SK Chemistry and Eastman (USA) in Korea.

Market prices range from 13500 to 22000 yuan/ton (average price)

According to market, brand and brand

There will be increases and decreases.

PETG has good viscosity, transparency, color and chemical resistance.

Resistance to stress whitening. It can be quickly hot-formed or extrusion blow-moulded.

Viscosity is better than acrylic acid. PETG products are highly transparent and tough.

It is suitable for forming thick-walled transparent products. PETG has excellent processing and moulding properties.

Ability to design arbitrary shapes according to the designer's intentions.

There are many kinds of PETG moulding methods, such as extrusion, injection, blow moulding and suction moulding.

PETG material is widely used in cosmetic packaging.

For example, perfume cover, lipstick tube, cream cream container, cosmetic box.

Deodorant packaging, talcum bottles and eyeliner covers.

PETG is an environmental protection material, which meets the requirements of food contact management.
