As a Top 5 global manufacturer of synthetic leather, WINIW equips B2B clients with the knowledge to identify materials that align with their product goals. While PVC and PU leather share similarities, understanding their differences ensures optimal performance, compliance, and cost-efficiency. Here are the best 5 ways to distinguish them—and why partnering with WINIW guarantees quality for your projects.
1. Texture and Flexibility
- PU Leather: Feels softer and more pliable, closely mimicking genuine leather’s natural suppleness. WINIW’s high-grade PU leather flexes without creasing, ideal for luxury handbags and apparel.
- PVC Leather: Slightly rigid with a plastic-like feel. WINIW’s heavy-duty PVC prioritizes structural durability for industrial gear and outdoor furniture.
Pro Tip: Fold a corner of the material. PU leather bends smoothly, while PVC may show slight resistance or a “memory” effect.
2. Breathability Test
- PU Leather: Microporous structure allows minimal air and moisture passage, making it breathable for footwear and car seats. WINIW’s perforated PU leather enhances airflow for automotive interiors.
- PVC Leather: Non-porous and waterproof, blocking all air and moisture. This makes WINIW’s PVC a top choice for rainwear and medical covers.
Pro Tip: Place a small section over steam. PU leather will allow slight vapor penetration; PVC will not.
**3. Burn Test (For Scrap Material)**
- PU Leather: Burns slowly with a blue flame, emitting a faint, sweetish odor. Leaves soft, crumbly ash.
- PVC Leather: Resists ignition initially, then burns with a greenish flame and strong chlorine-like smell (due to its vinyl content). Leaves hard, dark residue.
Note: WINIW’s fire-retardant PVC and PU leather meet ASTM/UL standards, but always test scraps in controlled environments.
4. Water Absorption
- PU Leather: Absorbs small amounts of water, causing temporary darkening. WINIW’s water-resistant PU uses hydrophobic coatings to delay absorption.
- PVC Leather: Fully waterproof. Drops bead up and wipe off effortlessly, a key reason WINIW’s PVC dominates marine upholstery and outdoor gear.
Pro Tip: Dab a wet cloth on the surface. PVC remains unaffected; PU may show slight dampness.
5. Backing Material Inspection
- PU Leather: Typically bonded to a fibrous fabric (e.g., polyester knit) visible on the underside. WINIW’s eco-PU uses recycled backings for sustainability.
- PVC Leather: Backed with thick woven fabric or mesh for rigidity. WINIW’s industrial-grade PVC features cross-stitched polyester for tear resistance.
Pro Tip: Scrape the back layer gently. PU reveals fabric fibers; PVC shows a smoother, plastic-coated texture.
