PET material, English name Polyethylene terephthalate, commonly known as polyester resin, is the most important variety of thermoplastic polyester.
Features of PET material:
1. The thermal deformation temperature and long-term use temperature of PET are the highest among thermoplastic general engineering plastics;
2. Due to the high heat resistance of PET, the reinforced PET material is immersed in a solder bath at 250 ° C for 10S, and it is hardly deformed or discolored;
3. The bending strength of PET material is 200MPa, the elastic modulus is 4000MPa, the creep resistance and fatigue resistance of PET are also very good, the surface hardness is high, and the mechanical properties of PET are similar to those of thermosetting plastics;
4. Since the ethylene glycol used in the production of PET is almost half the price of butanediol used in the production of PBT, PET is the lowest price among engineering plastics and has a high cost performance.
PET materials are mainly used in various blister packaging products, such as PET blister trays, PET blister boxes, etc.
PETG material is briefly a kind of transparent plastic, which is an amorphous copolyester. The commonly used comonomer for PETG is 1,4-cyclohexanedimethanol (CHDM), which is 1,4- Cyclohexanedimethanol comonomer.
Features of PETG material:
1. It has excellent transparency and smoothness, and has a good display effect.
2. Excellent surface decoration performance, can be printed without surface treatment, easy to emboss patterns, easy to metal treatment (vacuum metal plating layer)
3. Has good mechanical strength.
4. Good barrier properties to oxygen and water vapor.
5. Good chemical resistance, can withstand the erosion of various chemical substances.
6. Non-toxic, reliable hygienic performance, good adaptability to environmental protection, and can be recycled economically and conveniently; no environmentally harmful substances are produced when the waste is incinerated.
PETG materials are mainly used in household utensils such as PETG cups, PETG salad bowls, PETG salt shakers, PETG pepper shakers and other injection-molded products.
