Brief introduction of Polymer PETG sheet

First, the introduction

PETG is a non-crystalline copolyester. In the production process, since a certain amount of ethylene glycol is replaced by 1,4-cyclohexane dimethanol (CHDM), crystallization can be prevented, thereby improving processing and transparency.

Second, the characteristics

1, outstanding thermoforming performance

PETG sheets are easy to produce products with complex shapes and relatively large stretches, and unlike PC boards and impact-modified acrylics, such sheets do not need to be pre-dried prior to thermoforming. Compared with PC board or acrylic, the molding cycle is short, the temperature is low, and the yield is high.

2, toughness

Extrusion sheets of PETG sheets are typically 15 to 20 times tougher than general-purpose acrylics and 5 to 10 times tougher than impact-modified acrylics. PETG sheets are sufficiently tolerant during processing, transportation and trial use. Help prevent rupture.

3, weather resistance

PETG sheets offer excellent weatherability. It can guarantee the toughness of the product and prevent yellowing. It contains a UV absorber that can be coextruded into a protective layer that protects the board from the harmful effects of UV light.

4, simple processing

PETG sheets can be sawed, die cut, drilled, punched, sheared, riveted, milled and cold-bent without breaking. Slight scratches on the surface can be eliminated with a heat gun. Flux bonding is also a common operation. It is easier to process than general-purpose acrylic, impact-modified acrylic or PC sheet, and can be processed by flocking, electroplating, and static electricity.

5, environmental protection

PETG sheet substrates are environmentally friendly materials that meet food contact management requirements.

6. Economical

It is cheaper than a PC board and more durable than acrylic.

7, excellent chemical resistance

PETG sheet can withstand a variety of chemicals as well as commonly used cleaners
