Som enTop 5 global manufacturer of synthetic leather, WINIW equips B2B clients with the knowledge to identify materials that align with their product goals. While PVC och PU-läder 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
- â € <PU läder: 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.
- â € <PVC läder: Slightly rigid with a plastic-like feel. WINIW’s heavy-duty PVC prioritizes structural durability for industrial gear and outdoor furniture.
Proffstips: Fold a corner of the material. PU leather bends smoothly, while PVC may show slight resistance or a “memory” effect.
2. Breathability Test
- â € <PU läder: 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.
- â € <PVC läder: Non-porous and waterproof, blocking all air and moisture. This makes WINIW’s PVC a top choice for rainwear and medical covers.
Proffstips: Place a small section over steam. PU leather will allow slight vapor penetration; PVC will not.
**3. Burn Test (For Scrap Material)**
- â € <PU läder: Burns slowly with a blue flame, emitting a faint, sweetish odor. Leaves soft, crumbly ash.
- â € <PVC läder: Resists ignition initially, then burns with a greenish flame and strong chlorine-like smell (due to its vinyl content). Leaves hard, dark residue.
Anmärkningar: WINIW’s fire-retardant PVC and PU leather meet ASTM/UL standards, but always test scraps in controlled environments.
4. Water Absorption
- â € <PU läder: Absorbs small amounts of water, causing temporary darkening. WINIW’s water-resistant PU uses hydrophobic coatings to delay absorption.
- â € <PVC läder: Fully waterproof. Drops bead up and wipe off effortlessly, a key reason WINIW’s PVC dominates marine upholstery and outdoor gear.
Proffstips: Dab a wet cloth on the surface. PVC remains unaffected; PU may show slight dampness.
5. Backing Material Inspection
- â € <PU läder: Typically bonded to a fibrous fabric (e.g., polyester knit) visible on the underside. WINIW’s eco-PU uses recycled backings for sustainability.
- â € <PVC läder: Backed with thick woven fabric or mesh for rigidity. WINIW’s industrial-grade PVC features cross-stitched polyester for tear resistance.
Proffstips: Scrape the back layer gently. PU reveals fabric fibers; PVC shows a smoother, plastic-coated texture.
