PETG sheet has outstanding toughness and high impact strength. Its impact strength is 3-10 times that of changed polyacrylates, and it's a large process vary, high mechanical strength, and wonderful flexibility. Compared with PVC, PETG has a higher transparency, good gloss, easy printing, and environmental protection advantages. Do you know or understand PETG bottles? A PETG bottle is a cosmetic bottle or skincare bottle made of PETG material. PETG bottles are very common in our daily lives. Next, let's take a look at what the PETG bottle is. Here are some answers.
Here is the content list:
The concept of the PETG bottle.
PETG bottle is the main product of PETG.
PETG is a transparent, non-crystalline copolyester. The commonly used comonomer of PETG is 1,4-cyclohexane-di-methanol (CHDM, Cylclohexylenedimethylene), the full name is polyethylene terephthalate-1,4 -Cyclohexane di-methanol ester. It is a polycondensation product of terephthalic acid (PTA), ethylene glycol (EG), and 1,4-cyclohexane-di-methanol (CHDM) by the transesterification method, which is 1,4 more than PET -Cyclohexane di-methanol comonomer, which has more ethylene glycol comonomer than PCT. Therefore, the performance of PETG is very different from PET and PCT, and it has its uniqueness. Because the CHDM within the polymer will increase, the freezing point decreases, the glass transition temperature will increase, and therefore the crystallinity decreases, and eventually, an amorphous compound is created. Generally, the content of CHDM in PETG bottles is 30%-40%. PETG bottle has good viscosity, transparency, color, chemical resistance, and resistance to stress whitening.
PETG is highly transparent, not easily broken, and easy to surface modifier. PETG meets the US FDA's food contact standards and can be used in food and medical products and other fields. PETG improves the lack of low toughness of traditional polyester beverage bottles and is especially suitable for manufacturing large-volume thick-walled transparent containers, such as PETG bottles. PETG has glass-like transparency and density on the point of the glass, good gloss, chemical resistance, impact resistance, and is straightforward to method and might be injection wrought, injection stretch blow molding, and extrusion blow molding. It may manufacture distinctive shapes, appearances, and tricks, like bright colors, matte, marble texture, gold-bearing luster, etc. Moreover, another polyester, elastic-plastic, or ABS can also be used for overlapping injection molding. Products include PETG bottles, perfume bottles and caps, cosmetic bottles and caps, lipstick tubes, cosmetic boxes, deodorant packaging, talcum powder bottles, and eyeliner sets, etc.
