PU leather peeling is not a single failure with a single cause. A cracked surface film, a finish separating from the skin layer, a PU coating detaching from its backing, and a weak backing tearing apart can all look like…
Flame-retardant synthetic leather must balance properties that often conflict: flexibility, adhesion, low smoke, colour stability, ageing resistance and compliance with a finished-product fire test. A 2026 polyurethane-elastomer study is notable because it combines high elongation, reactive flame-retardant chemistry and strong…
Digital printing can shorten development cycles and reduce screen-making requirements, but synthetic leather presents a difficult surface. Unlike absorbent fabric, PU and PVC skins are relatively closed, flexible and often treated with low-surface-energy finishes. The ink must wet the surface,…
A thin waterborne polyurethane clear coat is often expected to improve abrasion, touch, gloss and resistance to plasticizer migration in PVC synthetic leather. Recent long-term ageing research shows why this assumption must be tested against the exact PVC formulation. What…
Waterborne polyurethane adhesives can reduce solvent use, but wet peel strength and hydrolysis durability remain critical barriers in footwear, microfiber leather and laminated synthetic leather structures. Catechol chemistry—best known from mussel-inspired adhesion—offers one route to improve performance at wet interfaces.…
Buyers often ask for a “breathable PU resin,” but breathability in synthetic leather is not controlled by resin chemistry alone. The backing structure, impregnation level, coagulation conditions, pore connectivity, skin-layer thickness and finishing process form a single transport system. If…
Fluorine-free water repellency is becoming a practical development requirement for footwear, bags, furniture and automotive trim. The difficult part is not producing a high water-contact angle in a laboratory. It is preserving flex resistance, intercoat adhesion, printability, cleanability and consistent…
Plasticizer selection determines much of the flexibility, low-temperature behaviour, odour, fogging, migration and ageing performance of PVC synthetic leather. A material described as “phthalate-free” can still fail if the replacement plasticizer migrates, extracts, blocks or raises processing viscosity. Two 2026…
A deep technical analysis of the development paths for sustainable synthetic leather, from solvent-based to waterborne, solvent-free, and bio-based systems.
For B2B material buyers: REACH, California Proposition 65 and OEKO-TEX STANDARD 100 address different questions. They are not interchangeable badges, and no statement should be applied to every faux leather product without checking the exact material, color, backing, finish, production…
