Working with Bonded Leather Board HD-095
Is Bonded Leather Board easy to machine?
Die-cut, clicker-press, skive or laser/CNC-knife cut cleanly; carbide or hardened steel blades last longer because chrome-tanned fiber and mineral filler are abrasive, and laser cutting produces burnt-leather odor.
Can Bonded Leather Board be welded?
Not weldable — join by contact/latex/PU adhesive, stitching, riveting or heat-set edge binding.
Can Bonded Leather Board be formed, bent or molded?
Dampen or steam and press-form in a heated mold (roughly 60–90 °C) to hold three-dimensional shapes; dry fully before assembly to avoid springback and shrinkage.
What surface finishes work on Bonded Leather Board?
Accepts edge burnishing, embossing, water-based dye or pigment coating, PU top-coat and flocking; seal edges against moisture uptake, and never use solvent or acid strippers that attack the binder.
Bonded Leather Board chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| leather fiber (collagen, chrome/veg tannrecovered tannery splits, shavings and buffing dust | 60 – 90 | 78 |
| natural latex / SBR binderPU or acrylic resin in water-resistant grades | 8 – 25 | 15 |
| mineral filler (kaolin, CaCO3, talc)density/stiffness control | 0 – 12 | 4 |
| fatliquor, plasticizer, dye, biocide | 0.5 – 5 | 2 |
