How to distinguish the genuine from the counterfeit TPU PPF-Folie?
It’s actually not difficult to determine the authenticity of TPU PPF film. We can start by focusing on these key points:
First, let’s look at the color and texture
True TPU: Transparent or translucent, with good quality even showing a hint of fluorescent blue, and it feels soft and elastic to the touch.
Fake TPU: It is bluish or milky white, sticky to the touch, and prone to fading.
II. Hands-on testing is more reliable
Tensile test:
Genuine TPU can be stretched 5-7 times without breaking and rebounds quickly.
The fake material turns white after being stretched, and it breaks if stretched beyond 30%.
Combustion test:
True TPU burns with an ethanol odor, and the residue is a viscous liquid.
The fake one emits black smoke, has a pungent smell, and produces hard and brittle ash.
Puncture test:
The real TPU cannot be squeezed through with a screwdriver and will return to its original state.
A fake item will break easily with just a slight wear.
III. Don’t overlook the details
Glue smell: Genuine TPU glue is odorless or has a slight odor, while fake ones often have an alcohol smell.
Self-healing ability: True TPU scratches can be repaired within 2 hours under warm water.
IV. Professional Identification
Stretching test: The true TPU coating appears filamentous and uniform after stretching.
Flame retardant test: After burning, real TPU leaves no trace when wiped with a wet towel.
Tips: Choose a reliable brand. Be wary of products with too low a price. If in doubt, seek professional inspection.
