PET (Polyethylene terephthalate)

What is PET (Polyethylene Terephthalate)?

The material is known for its good mechanical strength, dimensional stability and recyclability, making it one of the most widely used plastic materials in the world.

Important properties of PET (Polyethylene Terephthalate)

• High mechanical strength – PET has good stiffness and impact resistance, which makes it durable even under load.
• Excellent chemical resistance – Resistant to oils, fats, acids and alcohol, making it useful in food and industrial environments.
• Good heat resistance – Can withstand temperatures up to approximately 70–80°C in standard versions, while some modified PET variants can handle higher temperatures.
• Low friction and high wear resistance – Perfect for moving parts and technical components.
• Dimensionally stable and moisture resistant – Retains its shape even in humid conditions, unlike some other plastics.
• Transparent or tinted – PET can be completely transparent, making it ideal for packaging and optical applications.
• Easy to injection mold and extrude – Good machining ability when producing high-precision parts.
• 100 % recyclable – PET is one of the most recycled plastic materials in the world and is often used in circular production processes.

Different types of PET (Polyethylene Terephthalate) and their uses

• Amorphous PET (A-PET) – High transparency and good impact resistance. Used in food packaging, blister packaging and protective films.
• Crystallized PET (C-PET) – Withstands higher temperatures and has better dimensional stability. Used in microwave-safe food packaging and technical components.
• Fiber-reinforced PET – Has higher stiffness and wear resistance. Used in technical plastic parts, machine components and vehicle parts.
• PET-G (Modified PET) – Has improved impact resistance and can be thermoformed more easily. Used in displays, sign materials and medical devices.
• Recycled PET (rPET) – Made from recycled bottles and other PET products. Used in textiles, new bottles, packaging and technical components.

How do we use PET (Polyethylene Terephthalate) in our production?

We use PET in a variety of applications where strength, chemical resistance and recyclability are crucial.

Some of the most common uses are:

• Food packaging – PET is used in bottles, cans and food trays due to its transparency and food safety.
• Technical plastic parts – Fiber-reinforced PET is used in moving parts, gears, bearings and other industrial components where wear resistance and low friction are important.
• Automotive industry – PET is used in interior details, fans and electrical components where low weight and high mechanical strength are needed.
• Packaging and protective plastic – PET is used in blister packaging and protective wrapping where transparency and durability are important factors.
• Textiles and composite materials – Recycled PET is used to manufacture polyester fibers for clothing, bags and technical textiles.

Why do we choose PET (Polyethylene Terephthalate)?

PET is a versatile material with many advantages, including high strength, good chemical resistance and recyclability. Its combination of light weight, transparency and mechanical performance makes it one of the most widely used plastic materials in the world.

To optimize PET for specific needs, we can modify it with:

• UV stabilizers – For longer life when used outdoors.
• Flame retardant – For safety requirements in the electronics and automotive industries.
• Antibacterial additives – For hygienic products in medicine and food.

In summary, PET is a sustainable and high-performance material used in everything from technical components to packaging and textiles.
