Types of Synthetic Leather: The Complete Classification Guide
Synthetic leather can be classified by resin type (PVC, PU, TPU, silicone, polyolefin), by backing structure (woven, non-woven, microfiber, split-leather), by production process (dry, wet, calendering, solvent-free), and by finish or eco-origin — with PU and PVC accounting for the vast majority of global trade volume.

Synthetic leather is not one material — it’s a family of products that differ by resin chemistry, backing construction, manufacturing process, surface finish, and raw-material origin. Buyers who understand these distinctions can specify the right material instead of relying on a supplier’s marketing name. This guide organizes the entire category into one reference so you don’t have to piece it together from a dozen inconsistent competitor pages.
The Short Answer
Every synthetic leather product can be described along five independent axes: (1) what resin coats the surface (PVC, PU, TPU, silicone, polyolefin), (2) what backing it’s built on (woven/knit fabric, non-woven fabric, microfiber non-woven, or genuine split-leather), (3) how it was manufactured (dry lamination, wet coagulation, direct coating, calendering), (4) how the surface was finished (embossed, suede, patent/mirror), and (5) what raw material the resin comes from (petroleum-based or bio-based). Most product names you see from suppliers (“PU leather,” “microfiber leather,” “vegan leather”) are really shorthand that combines two or three of these axes at once.
1. Classification by Resin Type (Face Coating)
This is the most commercially important axis — it determines cost, feel, and durability more than any other single factor.
| Resin | Core material | Feel & cost | Typical use |
|---|---|---|---|
| PVC leather | Polyvinyl chloride | Stiffer, less breathable, lowest cost | Budget bags, sports balls, industrial upholstery, marine/outdoor |
| PU leather | Polyurethane | Soft, breathable, mid-to-premium cost | Footwear, bags, garments, automotive, furniture — the global default |
| TPU leather | Thermoplastic polyurethane | Very high abrasion/cold resistance, premium cost | High-end sports balls (soccer), outdoor gear |
| Silicone leather | Silicone polymer (PDMS) | Rubbery hand-feel, near-zero VOC, very high heat/hydrolysis resistance, premium cost | Medical devices, high-end automotive, baby products |
| Polyolefin leather | PP / PE | Chemically inert, low density (can float) | Outdoor furniture, industrial protective covers |
See our detailed guides: What is PU Leather? and PU vs PVC Leather.
A trade-data caveat worth knowing
Our PU vs. PVC market share analysis is built on three official Chinese customs HS codes — 59032020 (PU), 59031020 (PVC), and 59039020 (all other plastic-coated). TPU, silicone, and polyolefin leathers do not have their own customs code — depending on formulation, customs classifies them under one of these three existing buckets (most often “other plastic-coated,” which is consistently under 2.5% of total export value). So while we can say with data-backed confidence that PU dominates ~70% of the market and PVC ~25–30%, we cannot claim a precise, independently-sourced trade share for TPU or silicone leather specifically — any number you see quoted for those niches elsewhere in the industry is an estimate, not an official statistic.
2. The Factor Most Guides Skip: Hydrolysis Resistance (Ester vs. Ether PU)
If you’ve ever seen PU leather turn sticky, crack, or “peel” after a couple of years, the cause is almost always hydrolysis — the polyurethane’s ester or ether bonds breaking down when exposed to moisture and heat over time. This is arguably the single most important spec for any buyer sourcing PU leather for long-life products, and it depends on which PU chemistry was used:
| PU type | Hydrolysis resistance | Cost | Typical lifespan in humid climates |
|---|---|---|---|
| Ester-based PU | Poor — breaks down faster in heat/humidity | Lower | 1–3 years before visible degradation |
| Ether-based PU | Good — much more stable in humid/tropical conditions | Higher | 5+ years, standard for export-grade product |
If you’re sourcing for markets with high humidity (Southeast Asia, coastal climates) or products with a multi-year warranty (automotive, furniture), always confirm with your supplier whether the PU resin is ester- or ether-based — not just “PU leather.” Read more in our guide on how to prevent PU leather from peeling.
3. Classification by Backing / Structure
| Backing type | Structure | Typical product |
|---|---|---|
| Woven/knit fabric backing | Standard textile base | General-purpose PU/PVC leather |
| Non-woven backing | Bonded synthetic fiber mat | Mid-range PU leather |
| Microfiber (superfine fiber) backing | 3D non-woven network of sub-micron fibers, impregnated with PU | Premium synthetic leather, closest to genuine leather structure — see Microfiber Leather |
| Split-leather backing (bicast) | Genuine leather split coated with a PU film | “Bonded leather” / “PU leather” that is part genuine hide |
| Bonded/reconstituted leather | Shredded genuine-leather fiber pressed with binder | Budget “genuine leather” alternative, distinct from PU/PVC |
Backing fiber composition also matters for compliance
Buyers requesting GRS (Global Recycled Standard) certification should specifically ask whether the backing uses rPET (recycled polyester) fiber — this is the standard route to GRS-certified synthetic leather. Backing fiber composition (polyester, cotton/poly blends, nylon for premium microfiber) also affects tear strength and hand-feel independent of the face coating.
4. Classification by Production Process
| Process | How it works | Typical result |
|---|---|---|
| Dry process (transfer coating) | Resin cast onto release paper, dried, then laminated to backing | Most PU/PVC leather — wide range of finishes |
| Wet process (coagulation) | Backing impregnated with PU solution, coagulated in a water bath to form a microporous structure | Breathable PU used in shoe linings, sports balls, sofa leather |
| Direct coating | Resin applied straight onto the backing surface | Simpler, lower-cost product |
| Calendering | PVC heated and rolled into a film, then laminated | Most PVC leather |
| Solvent-free / waterborne process | No DMF or other organic solvents | Lower-VOC PU leather, increasingly required by EU/US buyers |
5. Classification by Surface Finish
- Embossed — pattern pressed in by a textured roller or mold (lychee grain, pebble grain, croc/alligator emboss, Nappa-style grain)
- Suede / microsuede finish — sanded to create a soft napped surface
- Patent / mirror finish — high-gloss, smooth surface
- Color-shift / two-tone finish — appears to change color depending on light angle or rubbing direction
Grain and texture names are also how many buyers search — “crocodile leather,” “lychee pattern PU leather,” and similar terms describe finish, not material composition, and can apply to either PU or PVC bases.
6. Classification by Eco-Origin (and Avoiding Greenwashing)
Not all “eco” or “vegan” synthetic leather is the same, and the differences matter for compliance claims:
| Category | What it actually is | Still contains petroleum plastic? |
|---|---|---|
| Plant-residue composite leather (apple, pineapple/Piñatex, cactus) | Plant fiber/powder blended into a standard PU resin matrix | Yes — typically 30–50%+ PU by weight |
| Bio-based PU (Bio-PU) | Polyurethane where some or all polyol is derived from corn, castor oil, etc. | Partially reduced, not eliminated |
| Recycled/regenerated leather | Genuine leather scrap fiber reclaimed and rebonded | No new petroleum plastic, but not “vegan” in the strict sense |
| Mycelium (mushroom) leather | Lab-grown fungal mycelium, minimal/no synthetic resin | Closest to fully bio-based, currently high cost/limited scale |
We deliberately avoid blanket claims like “100% eco-friendly” for plant-residue composites, since most still contain a majority-PU resin matrix — the accurate claim is “reduced virgin-plastic content,” not “plastic-free.”
Other Specs Worth Asking Your Supplier About
Beyond material family, these cross-cutting specs affect real-world performance regardless of resin type:
- Colorfastness / rub fastness — rated on a gray-scale system (AATCC/ISO); important for garments and light-colored automotive interiors
- Fogging value — VOC off-gassing test required by automotive OEMs to prevent windshield haze
- Plasticizer type (PVC only) — phthalate-based (DOP) vs. non-phthalate (DINP/DOTP); relevant to REACH compliance for EU-bound shipments
- Flame retardancy rating — see our fire-safety certifications guide (CAL 117, BS5852, FMVSS 302)
Quick Reference: Which Type Should You Specify?
| If you need… | Consider |
