Fully Synthetic PU Leather
A polyurethane surface is applied to polyester, cotton, nonwoven, knit or microfiber backing. This construction can be animal-free when all layers and additives are confirmed accordingly.

Clear material answer for buyers
Is PU Material Fake Leather?
In a leather-look product, PU usually means polyurethane synthetic leather—not natural animal leather. But “PU material” is a broader term, and some PU-coated products may still contain a split-leather backing.
The accurate question is not simply “real or fake?” It is: what is the surface chemistry, what is the backing, and does the construction contain animal-derived material? This guide explains the difference and shows how to specify PU leather for commercial production.
Material categoryEngineered leather-like coated material
Typical surfacePolyurethane finish with embossed grain
Buyer verificationConfirm backing and composition in writing
Commercial valueControlled color, texture and roll consistency
The wording matters
PU Material Does Not Always Mean PU Leather
PU is the abbreviation for polyurethane, a broad family of polymers used in many products. It can appear in flexible foam, rigid foam, coatings, adhesives, films, sealants and elastomeric parts. Therefore, a label that says only “PU material” does not automatically describe leather or a leather substitute.
When the material has a leather-like grain and is used for upholstery, bags, shoes, automotive trim or decorative panels, “PU” usually refers to polyurethane synthetic leather. The surface provides the color, grain and hand feel, while the backing influences stretch, sewing behavior, tear strength and dimensional stability.
Practical labeling rule: use “PU synthetic leather” or “polyurethane-coated textile” for a fully synthetic construction. Avoid describing it as genuine, natural or full-grain leather.
A more accurate answer
“Fake Leather” Is Informal; Construction Is What Buyers Should Verify
Two products can both be marketed as PU leather while using different backings, coating systems and animal-content profiles. Clear specification language prevents sourcing mistakes.
PU-Coated Split Leather
A polyurethane film or finish is bonded to split animal hide. It contains real leather in the backing, so it should not be represented as fully synthetic or animal-free.
Bonded Leather Composite
Leather fibers may be combined with binders and finished with a synthetic surface. The percentage and structure vary, making a supplier composition declaration important.
Material anatomy
What Is PU Synthetic Leather Made Of?
PU leather is best understood as a layered engineered textile rather than a single solid sheet of polyurethane.
Layer 1
Protective top finishControls gloss, touch, stain resistance, scratch direction and cleaning behavior.
Layer 2
Embossed polyurethane surfaceCreates the leather-like grain, color and visual character.
Layer 3
Optional foam or bonding layerCan influence cushioning, body, adhesion and surface recovery.
Layer 4
Textile, nonwoven or microfiber backingProvides strength, stretch control, sewing support and processing stability.
Material comparison
PU Leather vs Bicast, Bonded and Genuine Leather
The table below is a sourcing guide. Final performance varies with formulation, backing, thickness, finishing, product design and use conditions.
| Material | Typical construction | Animal content | Commercial strengths | Buyer watchpoints |
|---|---|---|---|---|
| 100% synthetic PU leather | PU surface over textile, nonwoven or microfiber backing | Can be animal-free | Consistent color, custom grain, roll production, easy-clean options and predictable cutting yield | Confirm hydrolysis, abrasion, flexing, odor, backing and application suitability |
| PU-coated split / bicast leather | PU film or coating over split animal hide | Contains animal hide | Leather-containing base with controlled surface appearance | Must not be described as fully synthetic or animal-free |
| Bonded leather | Leather fibers combined with binders and a finished surface | Variable content | Uses leather-fiber composite with standardized sheets | Request the composition percentage and test standard |
| Genuine / natural leather | Tanned animal hide with natural fiber structure | Animal hide | Natural grain, patina potential and premium material identity | Hide variation, care requirements, cutting yield and cost control |
Where PU leather makes sense
Choose the Material by Application, Not by the Name Alone
PU leather can be commercially effective when its surface, backing and performance targets are matched to the finished product.
F
Furniture & Contract Seating
Review hand feel, abrasion direction, cleanability, color consistency, seam behavior and the expected intensity of use.
A
Automotive Interior Trim
Evaluate heat exposure, odor requirements, flexing, abrasion, color stability and compatibility with seat or panel construction.
B
Bags, Cases & Accessories
Check fold resistance, edge finishing, backing strength, surface recovery, embossing detail and cutting efficiency.
M
Medical & Easy-Clean Covers
Define the cleaning method, chemical-contact conditions, seam design, fluid resistance and any market-specific compliance pathway.
Professional sourcing checklist
How to Verify Whether a PU Material Is Fully Synthetic
A clear purchase specification is more reliable than a marketing label or product photo.
Ask the supplier these questions
- What is the exact surface chemistry: PU, PVC, silicone or a hybrid system?
- What is the backing: polyester knit, woven fabric, nonwoven, microfiber or split hide?
- Does any layer contain animal-derived leather fiber or hide?
- Can the supplier provide a written composition declaration?
- Which tests are available for abrasion, flexing, hydrolysis, color fastness or cleaning?
- Is the sample representative of the intended bulk-production construction?
Include these details in the RFQ
- Final application and expected service environment
- Target color, grain, gloss and hand-feel sample
- Backing type, thickness direction and roll width
- Cleaning frequency and chemical-contact conditions
- Abrasion, flexing, UV, hydrolysis or flame-retardant pathway
- Order quantity, packaging, labeling and destination market

Balanced buying advice
Advantages, Limitations and Care Expectations
PU leather is useful for many commercial products, but responsible material selection requires clear expectations.
Common Advantages
Controlled color and grain, broad design flexibility, roll-form processing, easy-wipe surfaces, repeatable product collections and a potentially animal-free construction when verified.
Common Limitations
Lower breathability than natural leather, no natural patina, and possible peeling, cracking or hydrolysis when the coating system is unsuitable for the application or service environment.
Care Direction
Use a soft cloth and mild cleaner suitable for the tested surface. Avoid harsh solvents, abrasive scrubbing, prolonged heat and cleaning agents that have not been verified on a hidden area.

Frequently asked questions
PU Material and Fake Leather FAQ
Is PU material fake leather?
When PU material is made and finished to imitate leather, it is usually a type of synthetic or faux leather rather than natural animal leather. “PU material” by itself is broader and can also refer to polyurethane foam, film, coating, adhesive or other products.
Is all PU leather animal-free?
No. Fully synthetic PU leather can use a textile, nonwoven or microfiber backing with no animal hide. PU-coated split leather or bicast leather contains an animal-hide backing. Buyers should confirm the construction and request a composition declaration.
Is PU leather the same as faux leather?
PU leather is one type of faux leather. Faux leather is a wider category that can include PU leather, PVC leather, silicone leather, microfiber synthetic leather and other coated leather-like materials.
How can I tell whether PU leather contains real leather?
Check the backing description and ask whether the construction includes split hide or leather fiber. Product photographs are not sufficient. A written bill of materials, composition declaration or supplier specification is more reliable.
Does PU leather peel or crack?
Some PU leather can peel, crack or hydrolyze over time, especially when coating quality, backing, cleaning method, temperature, humidity or usage intensity do not match the application. Performance should be evaluated using the intended specification and test pathway.
What information should I send DERFLEX for a PU leather quotation?
Provide the final application, color or sample, grain, gloss, hand feel, backing, thickness direction, roll width, quantity, cleaning conditions, performance requirements, packaging and destination market.
Need a Clearly Specified PU Synthetic Leather?
Send your target application, sample, color, grain, backing and performance requirements. DERFLEX can review the material structure and support a custom sample or bulk-roll quotation.
