product details
Introduce our products
PVC leather with sponge backing is a multi-layer synthetic composite material constructed by laminating a heavy-duty polyvinyl chloride surface skin onto a high-resilience polyurethane or PVC foam core. Engineered to simulate the plush volume and structural memory of natural leather padding, this composite delivers exceptional seam tear resistance ($\ge 40\text{ N}$), controlled elongation, and compliance with flame retardancy codes (FMVSS 302, CAL 117) for automotive interiors, marine seating, and high-traffic commercial contract furniture. Solamni provides continuous roll goods with strict thickness control ($\pm 0.05\text{ mm}$) to ensure seamless multi-ply automated CNC cutting.

Quality Control & Testing Standards
To eliminate inter-batch variation and structural delamination in high-volume shipments, Solamni implements destructive mechanical testing protocols across every production lot. Raw PVC resins and plasticizer blends undergo thermal stability screening before passing through multi-stage calendering machines, ensuring uniform melt homogeneity across $1.37\text{ m}$ ($54\text{ inch}$) usable widths.
| [Calendering Line Thickness Control] ---> [Flame Lamination & PUR Bonding] ---> [In-Line Electronic Thickness Gauging] | [SGS & REACH Certificate Release] <--- [Bally Cold Flex & Taber Abrasion QC] |
Lamination of the sponge layer is executed via precision flame bonding, where the PU foam surface is flash-melted to form an un-cleavable polymer bond with the textile substrate without requiring brittle solvent glues. Finished rolls pass through automated electronic measuring and optical defect scanners to guarantee zero gauge variations. In our internal laboratory, batch samples are subjected to:
- Taber Abrasion Testing (ASTM D3884): Minimum 50,000 cycles with CS-10 grit wheels under 1,000g load with zero surface foam exposure.
- Bally Flex Fatigue Testing (ISO 5402-1): Exceeding 100,000 continuous flex cycles at $-20^\circ\text{C}$ to guarantee zero cold-cracking at stress points.
Industrial Application Scenarios
Solamni sponge-backed PVC leather is engineered for heavy-duty manufacturing operations where structural volume, thermal insulation, and surface wear resistance are mandatory:
Automotive Aftermarket & OEM Interior Trims
Designed for automotive seat covers, door panel inserts, headliners, center armrests, and motorcycle saddlebags requiring deep grain embossing and seam strength.
Commercial Contract & Hospitality Furniture
Applied in high-traffic booth benches, KTV wall paneling, hotel headboards, and executive office seating subject to continuous compression and friction.
Marine & Outdoor Equipment
Formulated with UV-stabilized aliphatic topcoats and anti-fungal additives for boat lounge seating, jet-ski padding, and heavy-duty gym equipment pads.
