The Difference Between PVC, PP, PET and PETG

PVC (polyvinyl chloride), PP (polypropylene), PET (polyethylene terephthalate), and PETG (polytrimethylene terephthalate) are four different types of plastic materials.
They have some obvious differences in chemical structure, properties and uses.

Chemical structure:

PVC: Contains chlorine and is a polymer of vinyl chloride.
PP: Contains propylene element and is a polymer of propylene.
PET: is polyester made from the polymerization of terephthalic acid and ethylene glycol.
PETG: A modified version of PET with added propylene glycol (glycol) to improve its toughness.

Physical properties:

PVC: Good electrical insulation, chemical stability, corrosion resistance, but may not be resistant to high temperatures.
PP: It has high heat resistance and chemical stability and is a relatively hard plastic.
PET: Has good mechanical properties, transparency, and heat resistance, but can be brittle.
PETG: Compared with PET, it has more toughness and impact resistance.


PVC: widely used in construction, wires and cables, medical equipment and other fields.
PP: Used in food packaging, medical devices, auto parts, etc.
PET: Commonly found in beverage bottles, food packaging, fibers and films.
PETG: Due to its modifying properties, it is suitable for applications requiring higher toughness, such as display boxes, advertising signage, etc.

What is the Difference When Used as a Covering for Furniture or Doors?

When used as a covering for furniture or doors, the choice of different plastic materials (e.g. PVC, PP, PET, PETG) may depend on the specific performance and appearance requirements required. Here are some differences that may be involved in these applications:

Appearance and texture:

PVC: Available in a wide range of color options, the surface can have different textures to imitate wood grain, marble or metal effects.

PP: Usually uniform and glossy, suitable for some modern and simple designs.

PET: It has good transparency and is usually used for transparent or glossy surface decoration. It can also be used to produce imitation stone or wood grain.

PETG: While maintaining transparency, it is more tough than PET and can be used in situations requiring higher impact resistance.

Durability and abrasion resistance:

PVC: Has good wear resistance, is durable and relatively easy to clean.
PP: It has good wear resistance and is not easily damaged. It is suitable for decorative surfaces that will be used for a long time.
PET: Has good abrasion resistance and has a certain degree of resistance to scratches and abrasions.
PETG: It has impact resistance to a certain extent and is suitable for occasions with relatively high surface requirements.

Environmental protection:

PVC: Some unscrupulous merchants who only pursue low prices may contain harmful substances, LCL FILM‘s PVC films comply with EU environmental standards and are environmentally friendly, making them your absolutely trustworthy partner.
PP: Generally considered one of the relatively environmentally friendly plastic materials.
PET: Can be a recyclable material and relatively environmentally friendly.
PETG: Similar to PET and may be considered an environmentally friendly option.

Processing performance:

PVC: It can be processed in various ways such as thermoforming and is suitable for various complex surface shapes. It has rich color choices, surface textures and good wear resistance. The cost is relatively low and easy to process.
PP: It has good processing performance and is suitable for injection molding, extrusion and other processing processes. It may be simpler in appearance and relatively hard, so it depends on the design requirements.
PET: Usually processed through extrusion, calendering, etc., it has certain requirements for temperature and processing conditions, and may not be as good as other materials in terms of special design requirements.
PETG: PETG is more tough and impact-resistant than PET, while retaining transparency and gloss. May be advantageous in decorations requiring higher toughness. It has good processing performance and can be processed by extrusion, injection molding, etc. But the cost may be slightly higher than some other plastics.

In Conclusion

If you are pursuing relatively environmental protection, easier styling, more colors and designs, that is, suitable for all doorsfurniturewall panels, etc., you should choose PVC decorative film from a conscientious merchant, who will provide you with the most suitable solution (Choosing LCL FILM means choosing the RELIABLE partner). Of course, PVC is also by far the most cost-effective coating material in door and furniture manufacturing.

PET and PETG are more suitable for flat shapes when applied to furniture or doors.
In terms of environmental protection, PETG≈PET>PP>PVC. Of course, no matter which one you choose, as long as you choose a brand with an environmental protection mark, you are responsible for your customers.
