product details
Introduce our products
A solvent-free polyurethane (PU) synthetic leather with a matte smooth surface finish, engineered for footwear uppers, bag exteriors, automotive interiors, and furniture upholstery requiring low-light-reflection aesthetics. The material combines a 1.0mm base thickness with knitted backing, delivering peel strength ≥35 N/3cm, tensile strength ≥450 N/5cm (warp), and hydrolysis resistance validated through 36+ months jungle test exposure. Solamni maintains full customization (Pantone/RAL matching, 300+ stock texture patterns, 1.37m/1.4m width) with REACH and RoHS compliance documentation accompanying every shipment.

Solamni operates an ISO 9001:2015-certified in-house laboratory equipped with precision testing instrumentation to validate every production batch of PU synthetic leather against international performance standards. Each batch undergoes destructive and non-destructive physical testing, with automated Electronic Leather Measuring Machines for area yield optimization, high-precision Splitting Machines to maintain thickness tolerance at ±0.03mm, and calendering lines for uniform coating application.
Mechanical Property Testing
Tensile Strength & Elongation at Break: Validated per ISO 13934-2 using a Universal Testing Machine (UTM). Minimum acceptance: Warp ≥450 N/5cm, Weft ≥380 N/5cm, with elongation ≥18% (warp) and ≥22% (weft).
Tear Strength (Trouser Tear): Measured per ISO 13937-2, minimum acceptance ≥22 N (warp & weft), ensuring the material withstands puncture and seam tear-out during sewing and stitching operations.
Peel Strength: Adhesion between PU coating and knitted backing tested per GB/T8949 / CFFA-3, acceptance ≥35 N/3cm; delamination failure triggers batch rejection
Surface Durability & Flex Resistance
Abrasion Resistance (Martindale): Per ISO 12947-2, material must withstand ≥100,000 cycles without surface cracking or coating failure, simulating heavy-traffic commercial upholstery and footwear upper wear.
Flex Resistance (Bally Flex): Per ISO 5402-1, samples undergo 50,000 flexes at room temperature and 20,000 flexes at -10°C; acceptance requires no surface cracking or delamination, critical for footwear and automotive applications in cold climates.
Batch Traceability & Quality Documentation
Each production batch receives a unique lot number, linked to raw chemical supplier batch ID, coating line operator logs, and QC test records. Retained samples (3 rolls per batch) are archived for 24 months in climate-controlled storage (23°C ±2°C, 50% ±5% RH) for post-shipment verification-6. A Certificate of Compliance, including batch-specific test results and instrument calibration certificates, is issued with every shipment.
Industrial Application Scenarios
Footwear & Accessories: Engineered for sports shoe uppers (low-reflection surface for professional athletic footwear), fashion boot panels, bag exteriors, belts, wallets, and luggage. The knitted backing delivers high stitch-tear strength for secure sewing without needle blowout. Suitable for tongue lining and heel counter components requiring structural integrity and anti-slip surface.
Automotive & Marine: Applied in automotive aftermarket seat covers, dashboards, door panels, armrests, headliners, and boat interiors. The matte smooth surface reduces glare and light reflection, meeting automotive OEM interior requirements (SAE J1756). Material maintains flexibility and surface integrity under UV exposure (ISO 105-B02 Grade ≥4) and resists cracking across -20°C to +80°C temperature range.
Commercial Furniture & Contract Upholstery: Designed for heavy-traffic contract furniture in hospitality settings (hotels, restaurants, office lobbies, conference rooms). The low-gloss finish matches modern interior design aesthetics while the ≥100,000 Martindale abrasion cycles deliver durability against daily wear in sofa upholstery, restaurant booths, office chairs, and commercial seating.
Sporting Goods: Suitable for football panels, boxing gear, and gym equipment upholstery requiring robust surface friction and scuff resistance. Anti-mildew formulation (ASTM G21) ensures performance in humid environments.
FAQ
Q:What is the surface gloss rating of the matte smooth PU leather, and how is it controlled during production?
Q:Does the matte surface affect print adhesion or hot-stamping processes?
Q:What is the estimated cutting yield for the 1.0mm matte PU in automated die-cutting production?
Yield ≥95% with nested die layouts. Thickness tolerance ±0.03mm minimizes edge waste, reducing material consumption by 6-8% compared to natural leather hides. Contact Jason Lee for optimized pattern layout consultation.
