Material Overview
WINIW manufactures specialized fire-retardant (FR) synthetic leather engineered to slow down flame propagation, reduce smoke density, and prevent toxic gas emissions in critical public and industrial environments. Instead of applying temporary, easily washed-off topical coatings, we chemically integrate raw materials-such as halogen-free flame retardants-directly into the polymer matrices during the wet-coagulation or dry-coating extrusion phases.
Our fire-retardant roll goods are custom-formulated to satisfy strict B2B flammability standards across the automotive, commercial aviation, and hospitality furniture sectors, maintaining high elasticity and mechanical strength without compromising safety.
Verified Flammability Standards and Testing Metrics
Industrial procurement officers must design products that comply with regional life-safety regulations. WINIW's fire-retardant substrates undergo rigorous destructive testing in certified laboratories under specific sample orientations and ignition conditions:

Types of WINIW flame retardant synthetic leather
Material Structure Selection: Preventing Fire Hazards
Achieving high-grade flame retardancy requires selecting the right base polymers and backings. Below is how our different material structures are calibrated for flame performance:
1. Silicone Leather (Inherent Flame Resistance)
Silicone leather features an inorganic silicon-oxygen (Si-O) backbone. This unique chemical structure remains inherently flame resistant, naturally withstands extreme temperatures, and passes FAR 25.853 vertical burn codes without any added chemical retardants. It exhibits Grade 0 cytotoxicity, making it the premium selection for medical upholstery, infant care, and luxury electric vehicle (EV) seating.
2. Polyurethane (PU) Leather (Highly Customizable)
Standard PU is highly flammable. However, WINIW's FR polyether-grade PU is modified with nitrogen-phosphorus based halogen-free flame retardants. This formulation easily passes CAL TB 117-2013 and horizontal burn codes while maintaining the soft, drape-like texture required for safety footwear linings, residential sofa upholstery, and garments.
3. Polyvinyl Chloride (PVC) Vinyl (Heavy-Duty Performance)
PVC naturally contains chlorine, giving it moderate inherent flame retardancy. By adding non-volatile polymeric plasticizers and antimony trioxide synergists, we engineer PVC leather that meets the strict BS 5852 Crib 5 standard. This heavy-duty material is optimized for high-traffic contract hospitality seating, commercial theater benches, and public transport.

Custom FR Formulations for Global Markets
To comply with the chemical restrictions of global markets, WINIW avoids cheap, hazardous organohalogen fire retardants. We operate an eco-friendly production line utilizing:
- Phosphorus-Nitrogen Synergistic Systems: Expands into an insulating char layer upon heat exposure, cutting off oxygen and heat transfer to the base fibers.
- Halogen-Free & DMF-Free Compliance: Fully compliant with EU REACH Annex XVII, California Proposition 65, and RoHS directives.
- Low Smoke & Low VOC Output: Meets German VDA 278 standards, guaranteeing zero volatile outgassing, zero toxic smell inside vehicle cabins, and zero windshield fogging (DIN 75201).
Our Closed-Loop Custom Engineering Process
To satisfy strict public tenders, brand R&D compliance filings, and OEM specifications, WINIW operates a closed-loop custom development line to tailor-make the exact physical properties you need:
- Standard Analysis: You provide your target regulatory or industry codes (e.g., IATF 16949, EN ISO 20345, BS 5852 Crib 5).
- Formulation Matching: Our laboratory adjusts polymer cross-linking density, UV stabilizers (HALS), plasticizer molecular weights, and backing fibers.
- Pilot Lab-Dip Production: We manufacture physical swatches matching your custom Pantone color and gloss levels within 7 to 10 days.
- On-Site Destructive Testing: Swatches undergo Wyzenbeek double rubs, tropical chamber hydrolysis, and vertical flammability tests to verify compliance.
- Traceable Mass Production: Once approved, volume production is completed within 15 to 20 days with strict batch-code traceability.
Sourcing Policy: MOQ, Lead Time, and Packaging
- Minimum Order Quantity (MOQ): Our standard custom manufacturing MOQ for fire-retardant microfiber substrates is 300 linear meters per color and thickness. For standard PU or PVC formulations, the MOQ is 1,000 linear meters per color and thickness. For standard program stocks in black or white, we can dispatch trials starting from 100 linear meters to support your prototyping.
- Color Matching Consistency: Lot-to-lot color shading (ΔE) is a critical quality concern for automated assembly lines. Our laboratory utilizes automated gravimetric pigment dispensers and Datacolor spectrophotometers to maintain the overall color difference strictly under ΔE≤0.82 under standard D65 illuminants.
- Packaging and Transport: All bulk rolls are packed in dual-layer PE moisture-barrier roll wrapping with heavy-duty woven outer PP bags and labeled with unique traceable batch-code roll IDs.
Buyer Sourcing FAQs
Q: Can any WINIW material be made BS 5852 Crib 5 compliant?
A: BS 5852 Crib 5 is a severe vertical wood-crib flammability test. Standard lightweight PU (0.6mm) cannot pass this natively. Passing Crib 5 requires a thick substrate (typically ≥ 1.0mm) combined with high-density flame-retardant backing fabrics (woven polyester or non-woven matrix) and highly cross-linked surface polymers. Please specify your target standard when requesting swatches.
Q: Does adding fire-retardant chemicals degrade the physical strength of the leather?
A: Traditional flame retardants can weaken the tensile strength of polyurethane. At WINIW, we use micro-encapsulated synergistic additives and thermal cross-linking systems. This process maintains a high stitch tear strength (≥ 40 N under EN ISO 3377-2) and ensures the material survives over 100,000 Bally flex cycles without micro-cracking at the crease.
