The pros and cons of PETG plastic

Advantages:

It is first of all a transparent material, so the following many times will choose transparent material to contrast.

1) PETG is first and foremost a kind of highly transparent plastic.

It has excellent optical properties, high gloss surface and low turbidity. Its light transmittance is close to 90%, close to that of acrylic (PMMA) and better than that of polycarbonate (PC).

2) PETG has a wider range of chemical resistance (such as coffee, chocolate, grease, acid, etc.).

It has excellent chemical resistance to the following chemicals: automotive oil, soap, detergent, detergent, carpet cleaner, toothpaste and peppermint oil, perfume, cooking oil, 2-propanol, hydrocarbon solvents, etc.

3) It is one of the few environment-friendly plastic materials so far.

The reason why it is an environmentally friendly material, because it through

Only CO2 and water after burning, it can well protect the nature, since 2006, many developed countries such as Europe and the United States, is vigorously promotes the use of similar PETG environmental protection material (PETG have SGS, FDA, MSDN certification), PETG has become the environmental protection such as PVC transparent material is one of the preferred alternative, once your customers to use environmental plastic, PETG should be preferred.

4) PETG is especially suitable for forming transparent products with thick wall.

The transmittance of PETG with thick wall can also be protected

Besides, PETG product has a transparent ice-blue background that caters to the world trend. Its surface is extremely delicate and has a strong visual effect.

In addition, their thick wall or solid product interior, during the processing is not easy to produce bubbles.

(We have many transparent samples for guests to see, and these samples belong to the major brands).

5) PETG has extremely high toughness, excellent tensile resistance and good impact resistance.

Among transparent plastics, PC has the best toughness and impact resistance, but not good tensile strength.

The tensile properties, toughness and impact resistance of acrylic are not good;

While PETG has extremely high toughness and excellent tensile properties, its maximum tensile ratio can reach more than 180%, and its impact strength is several times that of acrylic. Another outstanding advantage of PETG is its physical and mechanical properties at low temperature

Hardly any change.

6) They have fun secondary processing properties.

Excellent ductility enables PETG to be processed in a variety of secondary ways

The formula becomes possible.

You can about their products for laser cutting, milling, die cutting, drilling, welding, punching, bending, cold bending (below 2.5 mm) limited, or fixed screw/bolt/rivet connection. The PC secondary processing performance is poorer, the reason is that the PC is relatively easy to produce stress concentration during molding, more than once in a manner of secondary processing, will thus breaking stress balance of PC products, or result in the crack of the product.

7) They have excellent printing and coating properties.

That is PETG plastic products surface do not need any special corona treatment, can do all kinds of printing, spraying, screen printing, pad printing, hot printing, etc.) or spraying, and good and bonding performance of the object surface Shanghai juji (note: although PETG chemical resistance is widely, but cannot guarantee that can spray all the content in the solvent resistance, please customers custom of PETG suitable for spraying) in advance.

.

8) They have excellent adhesion properties.

There can be a variety of voluntary bonding methods: such as general solvent, general adhesive, rub

Rub bonding, high frequency bonding, ultrasonic bonding, mechanical bonding (such as screws, rivets).

9)PETG has excellent low temperature resistance.

They can be used normally at -30℃, with minimum temperature resistance even up to

As a result, its products are very suitable for some cold regions (such as Russia, Canada, etc.), and its other characteristics also remain outstanding at low temperatures.

10)) They have good injection molding performance.

The injection molding process of PETG is relatively stable and does not require a specially designed injection molding machine. Its injection temperature is only about 215℃~235℃.

PETG is not susceptible to internal stress during injection molding due to their molecular structure and excellent ductility.

Disadvantages:

1) Too low thermal deformation temperature, only 75 degrees, will bring a lot of invariance

2) It is troublesome to dry, and difficult to dry.
