PETG & PCTG
PETG is a thermoplastic polyester that delivers significant chemical resistance, durability, and moldability for manufacturing. PETG is an adaptation of PET where the ‘G’ stands for glycol, such as CHDM or NPG, which is added at a molecular level to offer different chemical and optical properties.
Compared to PET, PETG has greater strength and durability, as well as being more impact resistant and better suited to higher temperatures. By adding more CHDM into the molecular chain, typically more than 40%, we can get PCTG, which has much higher impact performance, better chemical properties, and higher heat deformation temperature (HDT) than PETG.
Advantages
- Strong and Cost-Effective
PETG’s strength and impact resistance mean it is ideal for glazing and high-strength display units. It is also ideal for 3D printing products, displays, and signage.
PETG/PCTG don’t contain any BPA, so they are safe for use in food containers and bottles for drinks. They are also fully recyclable, which reduces waste and the potential negative environmental impact.
PETG/PCTG can be injection molded into a variety of shapes or extruded into sheets. PETG is both vacuum and thermoformable and can withstand high pressures without cracking.
PETG/PCTG are naturally transparent, which allows for unique optical effects, but both can also easily be colored and blended to create different appearances.
Applications
- PETG has applications in a range of industries due to being resistant to heat, impact, and solvents. It is widely used for food/drink containers, cosmetic packaging, film/sheet applications such as ID cards, advertising display, and shrinkable films.
- PCTG has better physical and chemical properties than PETG. It’s an ideal candidate for water/milk bottles, small home appliances, e-cigarettes, medical devices, etc.
