Semi PU leather · Application performance
ROYI develops Semi PU constructions around the finished component, required hand feel, backing movement and buyer-defined test plan. Development directions include seating, conductive ski-glove fingertips and four-way-stretch backing for shaped motorcycle seats.
Application performance
The material name alone does not define the right construction. Start with panel geometry, contact conditions, backing movement and the buyer’s validation method.
ROYI matches the surface layer and backing as one construction, then confirms the direction through application sampling.
Specify grain, hand feel and finish together with the intended abrasion or cleaning method. Approval should reference the finished seating construction, not a flat swatch alone.
Match the conductive surface to fingertip geometry, backing flexibility and bonding method. Conductivity and flex performance are confirmed on the buyer’s finished glove.
Stretch direction and recovery come from the backing and complete construction. The surface layer must be matched to forming, seam and appearance requirements through sampling.
Construction logic
The application routes above explain where Semi PU may fit. The next decision is how the surface system, material body and textile backing should work together—and how that complete construction will be approved.
Hydrolysis, UV, cleaning, seam, peel and flex performance require a defined test method, parameters and acceptance criteria. No result is assumed from the material name alone.
Abrasion test example
Selected sample result
Selected Semi PU sample constructions tested with a Taber abrasion tester using H-18 wheels and a 500 g load on each of two arms have reached 5,000–7,000 cycles without breakthrough.
Results depend on surface finish, thickness, backing and the complete test method. Use the approved sample and written specification as the production reference.
