The three materials look similar on a swatch card and behave very differently after a year in use. Here’s how they’re built, how they fail, and which one fits your product.
Short answer: Choose PVC when cleanability, cost and resistance to heavy wipe-down matter most, as in marine, healthcare and contract seating. Choose PU for fashion, bags and footwear uppers where hand feel and drape sell the product, and specify hydrolysis resistance. Choose microfiber leather when you need the closest match to genuine leather’s strength and structure, as in automotive, premium footwear and gloves, and can absorb a higher price per metre.
Key Takeaways
- PU is the largest faux leather category: Grand View Research puts its share at 57.7% of the synthetic leather market in 2024.
- The main long-term failure is different for each material: PVC stiffens and cracks in the cold, PU can break down through hydrolysis, and microfiber mostly shows finish wear.
- The backing (knit, woven, nonwoven or microfiber) drives tear strength and stretch as much as the coating does. Specify both layers.
- Pick the material first, then write the test requirements that protect against its known weakness. Don’t copy one spec sheet across all three.
How Is Each Type of Faux Leather Built?
All three are layered composites: a textile base, a polymer layer, and a surface finish that carries the grain, colour and gloss. The difference is what goes into each layer.
PVC leather
PVC (vinyl) leather is polyvinyl chloride compounded with plasticizers, stabilizers and pigment, then calendered or coated onto a knitted or woven backing. Often there’s a foamed middle layer for softness. Plasticizer content controls how soft the material feels and how well it flexes at low temperature. That makes the plasticizer type a compliance question as well as a comfort one (see our faux leather compliance guide).
PU leather
PU leather puts a polyurethane layer on a fabric base, usually by a dry transfer process: the PU is cast onto embossed release paper, laminated to the fabric, then the paper is peeled away to leave the grain. Many constructions add a wet-coagulated, microporous PU layer underneath for fullness and some breathability. PU chemistry matters: polyester-based PU tends to be more vulnerable to hydrolysis than polyether- or polycarbonate-based PU, which is why your spec needs a hydrolysis test rather than just “PU”.
Microfiber leather
Microfiber leather (often sold as “microfiber PU” or “superfine fiber leather”) starts from a nonwoven made of islands-in-the-sea fibres. The nonwoven is impregnated with polyurethane, and then the “sea” polymer is dissolved out. This leaves bundles of ultra-fine nylon fibres inside a PU matrix, a structure that research published in ACS Omega describes as combining nylon fibres and polyurethane. That bundled-fibre core imitates the collagen fibre network of hide, which is why microfiber cuts, skives and stitches more like genuine leather.
PU vs PVC vs Microfiber: Side-by-Side Comparison
The table below compares the three on the properties that usually decide a sourcing brief. Treat the ratings as relative. Individual constructions vary widely within each type, so confirm with test reports.
| Property | PVC | PU | Microfiber |
|---|---|---|---|
| Hand feel / drape | Firmer, more “plastic” | Soft, supple | Full, leather-like |
| Breathability | Very low | Low to moderate | Moderate |
| Tear and seam strength | Depends on backing | Depends on backing | High (fibre core) |
| Cleaning / disinfectant wipe-down | Excellent | Good (check chemistry) | Good |
| Main ageing risk | Plasticizer loss, cold cracking | Hydrolysis (peeling, flaking) | Finish wear, colour transfer |
| Relative cost | Lowest | Low to mid | Highest |
| Typical uses | Marine, healthcare and contract seating, luggage trim | Bags, apparel, footwear uppers, residential upholstery | Automotive interiors, premium footwear, gloves, sports goods |
Grand View Research estimates the global synthetic leather market at USD 41.05 billion in 2024 and projects it to reach USD 115.39 billion by 2033, with PU holding 57.7% in 2024. Market share tells you what’s widely available, not what’s right for your product. The sections below cover fit by application.
When Should You Choose PVC Leather?
Specify PVC when the product will be cleaned hard and often, or when price per metre is the deciding factor. Its closed, non-porous surface tolerates repeated disinfectant wipe-down, which is why it dominates hospital seating, marine upholstery and restaurant booths.
- Protect against its weakness: add a low-temperature bend requirement (ASTM D2136) if the product ships to or is used in cold climates, and state the test temperature.
- Ask about plasticizers: request the plasticizer type and a phthalate test report. Non-phthalate plasticizers are widely available, but you have to ask for them.
- Outdoor or marine use: add UV resistance and mildew resistance to the spec. Plain PVC is not automatically “marine grade”.
When Should You Choose PU Leather?
Specify PU when hand feel, drape and appearance drive the sale, as in handbags, jackets, footwear uppers, and residential sofas and chairs. PU takes fine embossing and printing well and is lighter than PVC at a similar thickness.
- Protect against its weakness: require hydrolysis testing (ISO 1419 Method C, the “jungle test”) and state the minimum number of weeks. Industry guidance commonly cites 3 weeks for residential and 5 weeks for commercial upholstery. Our testing standards guide explains why those weeks don’t convert into years of use.
- Ask about the process solvent: conventional solvent-borne PU uses DMF, which is now restricted in the EU. Waterborne and solvent-free PU lines exist; ask which one your quote is based on.
- Mind the backing: a knit backing gives stretch for garments and curved furniture, and a woven backing gives stability for bags and belts.
When Is Microfiber Leather Worth the Premium?
Microfiber earns its higher price where mechanical strength and leather-like processing matter: automotive seats and steering wheels, sports shoes, gloves, and premium bags that need to be skived, folded and edge-painted like hide. The nonwoven fibre core resists tearing at stitch lines far better than a thin knit backing, and it holds its shape after moulding.
It’s often over-specified, though. For a fashion bag with a one-to-two-season life, a well-built PU on a woven backing may do the job at a fraction of the cost. Start from the failure you’re trying to prevent, not the most premium option.
What About Silicone and Bio-Based Faux Leather?
Two newer categories are worth knowing. Silicone leather is valued for stain resistance, low odour and heat stability in medical, marine and hospitality seating, at a higher price. Bio-based PU leather replaces part of the petroleum-based polyol with plant-derived content, and constructions like cactus- or corn-based materials are usually PU with a declared bio-based percentage. If you plan to market bio-content, get the percentage verified by a test such as ASTM D6866, and read the 2026 green-claims rules before it goes on a hangtag.
Quick Decision Guide by Application
| Application | Usual first choice | Must-have test in the spec |
|---|---|---|
| Handbags, small leather goods | PU (woven backing) | Hydrolysis, colourfastness to rubbing |
| Apparel (jackets, trousers) | PU (knit backing) | Hydrolysis, flex resistance, wash/dry-clean care |
| Footwear uppers | PU or microfiber | Flex resistance, tear strength |
| Residential upholstery | PU | Abrasion, hydrolysis (≥3 weeks) |
| Contract / healthcare seating | PVC or silicone | Abrasion, cleanability, flammability |
| Marine / outdoor | PVC (marine grade) | Cold crack, UV, mildew resistance |
| Automotive interiors | Microfiber or PU | OEM material specs (fogging, odour, light fastness) |
Turn your choice into a spec a supplier can quote
Once you’ve picked the material, the next step is a spec sheet covering thickness, backing, finish, tests and compliance, so every supplier quotes the same thing.
Build Your Faux Leather Spec SheetFrequently Asked Questions
Is PU leather better than PVC leather?
Neither is better in general. PU is softer and more breathable, so it suits fashion, bags and residential furniture. PVC is tougher under repeated cleaning and usually cheaper, so it suits healthcare, marine and contract seating. Choose by the product’s use and cleaning regime.
How can I tell PU from PVC leather on a sample?
Look at the cut edge and the hand feel first: PVC often feels firmer and slightly cooler, and many PVC constructions show a foam layer. The reliable answer comes from the supplier’s material declaration or a lab identification test (for example, FTIR). Ask for it in writing rather than relying on a burn test.
Does microfiber leather peel like cheap PU?
Peeling in cheap PU usually comes from hydrolysis of the PU film or weak adhesion to a thin backing. Microfiber’s PU is impregnated through a dense fibre core rather than sitting on top as a separate film, so delamination is less common. The top finish can still wear, so specify abrasion and rubbing fastness.
Is “vegan leather” the same as PU leather?
“Vegan leather” is a marketing term for any leather alternative without animal content. Most of what’s sold under that name is PU. Some markets restrict using the word “leather” for non-animal materials at all; see the compliance guide.
Bottom Line
- PVC: for cleanability and cost. Add cold-crack and phthalate requirements.
- PU: for hand feel and appearance. Add hydrolysis requirements and ask about DMF.
- Microfiber: for strength and leather-like processing. Make sure the application justifies the premium.
