PET Sheet & Rod

Basic characteristics of PET

● Chemical structure: PET is a condensation product of terephthalic acid and ethylene glycol. Its molecular structure is highly symmetrical and has a certain crystal orientation ability.
● Physical form: PET is a milky white or light yellow highly crystalline polymer with a smooth and glossy surface.
● Mechanical properties: PET has good mechanical properties, and its impact strength is 3 to 5 times that of other films, and it has good folding resistance. At the same time, it also has excellent creep resistance, fatigue resistance, abrasion resistance and dimensional stability, with low wear and high hardness.
● Thermal properties: PET can be used for a long time within a temperature range of 120°C, and can withstand high temperatures of 150°C for short-term use, and can also withstand low temperatures of -70°C, and its mechanical properties are little affected by high and low temperatures. Through improvements, the heat deformation temperature and long-term use temperature of PET have become the highest among thermoplastic general engineering plastics.
● Barrier properties: PET has low gas and water vapor permeability and has excellent gas, water, oil and odor barrier properties.
● Optical properties: Amorphous PET has good optical transparency, high transparency, can block ultraviolet rays, and has good gloss.
● Electrical properties: PET has good electrical insulation properties and is less affected by temperature, but has poor corona resistance.
● Chemical stability: PET is resistant to oil, fat, olefinic acid, dilute alkali, most solvents, weak acids and organic solvents, but not hot water immersion and alkali. At the same time, PET is non-toxic, odorless, hygienic and safe, and can be directly used for food packaging.

What are the application scenarios of PET plastic materials?

PET (polyethylene terephthalate) plastics are widely used in many fields due to their excellent performance. Here are some of the main application scenarios:

Packaging materials:

● Beverage bottles: PET bottles are the most common packaging form in the beverage industry, including mineral water, juice, carbonated beverages, etc. PET bottles have the characteristics of light weight, high strength, good transparency, strong barrier properties, easy molding and recycling.

● Food packaging: PET is also used to make food packaging materials, such as edible oil bottles, condiment bottles, jam bottles, etc. These packaging materials have good air tightness and flavor retention, which can effectively extend the shelf life of food.

● Medical packaging: PET materials are also widely used in the field of medical packaging, such as making medicine bottles, medicine boxes, medical device packaging, etc. Its non-toxic, odorless and corrosion-resistant properties make it an ideal choice for medical packaging.

Electronics and electrical:

● Insulation materials: PET is widely used in the field of electrical insulation due to its good electrical insulation properties, such as the insulation layer of wires and cables, the insulation sheet inside electrical appliances, etc.
● Capacitor film: PET film is one of the key materials for manufacturing capacitors, with good dielectric properties and mechanical strength.

Construction and transportation:

● Sound insulation and heat insulation materials: PET materials can be made into sound insulation and heat insulation boards for sound insulation and heat insulation of buildings and vehicles.

● Automotive parts: PET is also used in the automotive industry, such as making automotive interior and exterior parts, lighting systems, etc.

Textiles and clothing:

● Fiber: PET fiber (polyester) is one of the most important synthetic fibers in the textile industry and is widely used in clothing, home decoration, industrial fabrics and other fields. Polyester fiber has the characteristics of high strength, good wear resistance, strong wrinkle resistance, easy washing and drying.

Optics and optical electronics:

● Optical film: PET film has important applications in the optical field, such as making polarizers, filters, reflective films, etc.

● Display materials: PET materials are also used to make backlight panels, light guide panels and other components of liquid crystal displays (LCDs).

Other applications:

● Magnetic recording materials: PET film is one of the basic materials for making magnetic recording materials (such as magnetic tapes).
● Protective materials: PET materials can also be made into protective clothing, protective gloves, etc., to prevent chemicals, radiation, etc. from causing harm to the human body.

In short, PET plastics play an important role in daily life, industrial production, scientific and technological research and development, etc. due to their unique properties and wide application fields.
