product details
Introduce our products
An oil-wax infused polyurethane synthetic leather engineered with a pull-up effect-surface color lightens temporarily under tension, returning to base tone upon release-replicating the patina behavior of full-grain oil-tanned leather. The 1.2-1.4mm material features a wax-impregnated topcoat with a matte, greasy hand-feel, delivering tensile strength ≥320 N/5cm, peel adhesion ≥25 N/3cm, and hydrolysis resistance through 36-month jungle test protocols. Solamni provides customized oil-wax loading levels, vintage effect intensity, and color development with REACH/RoHS documentation per shipment.

Solamni operates an ISO 9001:2015-certified laboratory. Validation protocols for vintage oil wax leather focus on pull-up effect consistency, wax migration control, and surface hand-feel uniformity.
Pull-Up Effect & Visual Validation:
Pull-up intensity measured via spectrophotometer: ΔE ≥3.0 between stretched (20% elongation) and relaxed states at 10 points per roll. Deviation beyond ±0.5 ΔE indicates inconsistent oil-wax distribution.
Wax bloom validation: samples placed at 60°C for 24 hours. Acceptable surface wax migration ≤0.5mg/cm². Excessive bloom indicates free wax content above specification, causing tackiness and surface discoloration.
Vintage effect intensity graded on a 1-5 scale against master standards; visual matching performed under D65 illuminant with 45° viewing angle.
Mechanical & Durability Testing:
Tensile and tear strength measured using UTM. The microfiber nonwoven substrate provides balanced warp/weft properties with minimal anisotropy.
Peel strength tested after 24-hour immersion at 23°C; acceptance ≥20 N/3cm wet-validating emulsion stability of the oil-wax impregnation.
Martindale abrasion at 50,000 cycles; post-test inspection for wax depletion at wear tracks and surface fiber raising.
Bally flex at 23°C (50,000 cycles) and -5°C (8,000 cycles). Oil-wax plasticization affects low-temperature flexibility; acceptance requires no cracking at scale intersections.
Oil-Wax Formulation & Stability:
Wax loading validated via Soxhlet extraction: target 8-12% wax by weight relative to PU topcoat. Higher loading increases pull-up intensity but reduces abrasion resistance.
DSC analysis confirms wax melting point within 50-65°C range, ensuring gradual wax migration during use rather than rapid surface sweating.
Industrial Application Scenarios
Heritage Footwear: Designed for work boots, desert boots, vintage sneakers, casual derby shoes, and heritage-style footwear where pull-up color variation and greasy hand-feel replicate aged leather character.
Vintage Furniture Upholstery: Used in Chesterfield sofas, wingback chairs, mid-century modern seating, and contract furniture for boutique hotels requiring a worn-in appearance with oiled leather texture.
Accessories: Applied in messenger bags, rucksacks, belts, journal covers, and leather goods where patina development is a design feature.
Automotive Restoration: Suitable for classic car seat covers, steering wheel wraps, and interior panels in vehicle restoration projects requiring period-correct oiled leather appearance.
FAQ
Q:Does the pull-up effect diminish with surface abrasion or cleaning?
Q:How does oil-wax loading affect cold flexibility?
Q:The material surface feels greasy-will this stain adjacent materials during shipping or storage?
Residual surface wax is minimal (<0.05mm). Solamni wraps each roll in kraft paper and places interleaving between layers. For stacked shipments, use polyethylene film separation. Surface bloom wipes clean with a dry cloth.
