What Is PU Leather?

PU leather (polyurethane leather) is a synthetic leather material produced by coating a fabric base—such as polyester or microfiber—with a polyurethane layer.

It is commonly referred to as:

PU leather material
Leather-like PU
Artificial leather
Synthetic leather
Faux leather or leatherette

PU leather is widely used in:

Furniture leather & upholstery leather
Interior fabrics and coated textiles
Automotive seating and trim
Bags, footwear, and accessories

Its popularity comes from design flexibility, cost efficiency, and consistent quality.

How PU Leather Is Manufactured

PU leather production typically involves:

Fabric substrate preparation
Application of polyurethane coating
Surface embossing or grain finishing
Curing, coloring, and performance treatments

Depending on technology, PU leather can be manufactured as:

Conventional solvent-based PU
Water-based PU
Solvent-Free PU
EPU leather (Eco-friendly PU)

Each method significantly affects environmental impact.

Why PU Leather Is Considered More Eco-Friendly Than Some Alternatives

PU leather is often viewed as a more sustainable option because:

✅ No Animal Farming

Unlike genuine leather, PU leather does not rely on livestock breeding, which contributes heavily to:

Greenhouse gas emissions
Water consumption
Land degradation

✅ Lower Environmental Impact Than PVC

Compared to PVC leather:

PU leather does not contain chlorine
It does not release dioxins during production or disposal
It is softer and requires fewer plasticizers

For this reason, PU leather is generally considered less harmful than vinyl-based materials.

✅ Lightweight & Resource Efficient

PU leather requires fewer natural resources and offers high production efficiency with minimal waste compared to animal hides.

Environmental Concerns of PU Leather

Despite these advantages, PU leather is not impact-free.

Key environmental concerns include:

Use of petroleum-based polymers
Chemical solvents in traditional PU production
Limited biodegradability
Microplastic concerns at end of life

Therefore, PU leather’s sustainability depends heavily on manufacturing technology and formulation.

Frequently Asked Questions (FAQ) – Upgraded Version

1) Is PU leather environmentally friendly?

PU leather can be a more environmentally considerate choice than PVC leather, and it avoids animal farming. But “eco-friendly” is not automatic — it depends on chemistry + manufacturing + end-of-life.

What makes PU leather more eco-friendly (in many cases):

No chlorine chemistry (compared with PVC), which can reduce certain environmental and disposal concerns.
Lower odor / lower VOC potential if the system uses water-based or low-solvent processes.
No animal-hide supply chain, which avoids impacts linked to livestock.

What can still make PU leather less sustainable:

Solvent-heavy production, poor VOC control, or non-compliant additives.
Very short product lifespan (the “most sustainable” material is often the one that lasts longer).
Limited recyclability because PU leather is typically a composite (PU layer + backing fabric).

How buyers should evaluate “eco” claims (practical checklist):

Ask for VOC / odor compliance (e.g., REACH / CA Prop 65 if relevant).
Confirm if it’s water-based PU or solvent-based PU.
Ask whether the supplier can provide material safety documentation (MSDS/TDS) and test reports.

2) Is PU leather biodegradable?

In most commercial applications today, traditional PU leather is not biodegradable in any meaningful timeframe, because it is designed for durability and contains stable polymer structures.

What’s changing:

Some manufacturers are developing bio-based PU (using renewable feedstocks) and modified PU systems that improve degradation pathways.
Important nuance: bio-based ≠ biodegradable. A product can contain bio-based content but still not biodegrade.

If your customer requires biodegradability:

Ask for recognized test standards and what condition it degrades under (industrial composting? landfill? marine?).
Watch out for “biodegradable” claims without third-party verification.

Best practice wording for projects:

If biodegradability is a must, treat it as a spec requirement and demand test-backed evidence, not marketing descriptions.

3) Is water-based PU better for the environment?

Generally, yes — water-based PU is widely considered a better option because it typically:

Reduces VOC emissions (less solvent use).
Improves indoor air quality during production and in finished products (odor control is often better).
Helps suppliers meet tighter compliance requirements more easily.

But it’s not always “better” in every spec:

Certain high-demand environments (heavy abrasion, hydrolysis resistance, extreme heat/humidity) require proper formulation; a poor water-based system can fail early.
Performance depends on the full structure: topcoat, basecoat, adhesion system, backing fabric, and curing.

What to ask suppliers (so you don’t get “green but weak”):

Abrasion test results (Martindale/Wyzenbeek).
Hydrolysis resistance / aging results (especially for hot & humid regions).
Odor / VOC test reports for hospitality or indoor projects.

4) What is EPU leather?

EPU usually stands for Eco/Environmental PU. In practice, it’s often used as a commercial term for PU leather made with:

Low-VOC / low-odor systems
Solvent-free or reduced-solvent production
Sometimes water-based PU
Sometimes restricted chemicals compliance (varies by supplier)

Key point:
“EPU” is not a globally fixed technical standard. Different suppliers can use the term differently.

How to make EPU meaningful in procurement:
Instead of accepting “EPU” as a label, specify what you actually need:

water-based PU (yes/no)
VOC/odor limit
restricted substances compliance
durability targets (abrasion, peeling strength, hydrolysis, color fastness)

5) Is PU leather suitable for hotel and commercial projects?

Yes — PU leather is widely used in hospitality and contract furniture, but only when the spec is engineered for project reality (traffic + cleaning + fire codes + climate).

Why PU works well in hotels/commercial spaces:

Good balance of appearance + cost + consistency (important for large batches).
Easier to control color/texture uniformity versus natural hide.
Can be engineered for functional needs like stain resistance and abrasion resistance.

What must be defined for hotel projects (avoid “sample ok, bulk fails”):

Fire retardancy requirement (which standard is needed depends on region/project).
Abrasion resistance target (high-traffic seating vs decorative panels differ).
Cleaning chemical resistance (alcohol wipes, disinfectants, stain removers).
Hydrolysis resistance (critical for Middle East humidity/heat, coastal projects, and long lifecycle).
Color fastness (light exposure in lobbies / near windows).

Common mistakes in contract projects:

Approving a small sample without confirming the final coating system and backing used in mass production.
Not specifying cleaning method; hotel housekeeping chemicals can destroy the topcoat.
Only asking “is it PU?” rather than setting measurable performance benchmarks.
