PET sheet (polyethylene terephthalate) is a common thermoplastic that provides high dimensional stability, excellent mechanical strength and good resistance to creep. It offers resistance to chemicals, provides very low moisture absorption and is a good electrical insulator. PET film sheet also performs well in wear applications and has a tough, hard surface that can be easily machined and polished.
Polyethylene terephthalate or PET belongs to the family of polyesters. It is widely used in everyday items and easily recyclable. It has a semi-crystalline form when stable. Most common application include rigid and flexible packaging as it is very light weight.
PET is among those plastics which are an important part of your everyday life. You find the polymer used in packaging, fabrics, films to molded parts for automotive, electronics and many more. For all the applications demanding lightweight and impact-resistant material, PET is of your choice. Also do not forget, PET is one of the most recycled thermoplastics as well.
PET sheet like transparent PET sheet and matt rigid plastic PET sheet are commonly manufactured into bearings, pump parts, components for frames, tank lids, insulators, friction strips and control discs. Primarily used in mechanical engineering, marine engineering, electrical and food and pharmaceutical applications. PET sheet is also manufactured into any kinds of packaging, commonly into food packaging, such as clamshell, egg tray, salad packaging, etc.
What is PETG?
Polyethylene terephthalate glycol, commonly known as PETG or PET-G, is a thermoplastic polyester that provides significant chemical resistance, durability, and excellent formability for manufacturing. PETG can be easily vacuumed and pressure-formed as well as heat-bent thanks to its low forming temperatures. This makes it exceptionally popular for consumer and commercial applications that involve 3D printing, or other heat-forming manufacturing techniques. Additionally, PETG is well-suited for fabrication techniques like die cutting, routing, and bending.
The Benefits of PETG Plastic
PETG is strong and cost-effective when compared to either acrylic or polycarbonate. Its unique characteristics make it preferable for impact-resistant glazing and high strength display units. Suitable for digital printing, PETG lends itself to product materials, displays, and signage. In general, PETG is a food-safe plastic that's commonly used for food containers and bottles for liquid beverages. Like acrylic and many other thermoplastics, PETG is fully recyclable.
PETG is both thermoformable and vacuum-formable, and can tolerate a tremendous amount of pressure without cracking. Although PETG is naturally clear, it takes color easily during processing. It can be injection molded into a variety of shapes, or extruded into sheets.
PETG's damage resistance is far higher than that of acrylic, to the point that it rivals the impact resistance of polycarbonate. However, PETG fabricates easily, making it an easy material for both practitioners and professional fabricators. Therefore it can be made into many products like PETG film roll, transparent rigid PETG sheet, matt rigid plastic PETG sheet, etc.
What's the Difference between PET and PETG?
Although these compounds look similar, they are fundamentally different materials on a molecular level. PET is the result of two monomers combining. PETG may involve these same monomers, but also includes glycol, giving it different chemical properties than PET. PETG is less brittle and more pliable than its PET counterpart, making it ideal for bottles. It also has better shock resistance and is better suited to higher temperatures.
