Bonded as mentioned earlier, is the lowest grade of leather. This means, goods made from this type of material don’t last for long.
And often the surface starts peeling within two to three years of continuous use.
What is PU/Faux Leather?
PU leather, also known as pleather or
leatherette, literally means
manmade. A type of
faux leather made to look and feel like an authentic rawhide leather without having to use any animal hide.
It is an imitation of the real thing; and often, if you’re not experienced with handling leather, you can mistake it for a real one.
There are many ways to make PU leather; however, the most common method used by manufacturers is to combine
polyurethane with split grain then paste it on a surface – this process ensures that PU goods are
cheaper.
The only thing going for this type of leather is that it is inexpensive. But,
it is not particularly durable. Hence, goods made of PU are likely to suffer some damages within a couple of years.
What is Bonded Leather?
Bonded leather, also called blended leather or reconstituted is a type of leather made from bonding together scrapes from the hide splitting process.
Remember, the hide splitting process we talked about earlier? Well, as you can imagine, during the process, scraps of leather are created. These tiny bits instead of being thrown away are gathered together then blended to form a new piece of material.
To make bonded leather, manufacturers often ground together with the scrapes of hides with plastics before sticking them unto a hard fiber surface. Then finish it off by adding coats of colors and paints which make the material resemble the real thing.
Depending on a manufacturer’s standard, the bonded material could contain as little as 20 percent real Leather and still be classified as a leather product. Though, in most countries, anything less than 20 percent are classified as faux.
