🪡 Oropal 120-40 TI — Leather Molding & Footwear Reinforcing Interlining (Oxford Gray)
Oropal 120-40 TI is a low-temperature, non-woven polyester interlining made for shaping and molding leather. Unlike a general fabric interfacing, it is formulated to bond directly to a leather cut piece and hold a shaped, molded form — the reinforcement shoemakers and leather workers use to build clean structure into uppers and shaped components. It fuses at a gentle 105–120 °C, low enough to protect heat-sensitive leather.
It is a go-to in footwear — especially boot uppers and vamps, reinforcing the instep area of full-cut uppers — and for leather goods that need moldable structure. Because it works at a low temperature and applies straight to the cut, it is fast and forgiving on the bench.
Please note: Oropal 120-40 TI is designed for leather and footwear components, not woven fabrics. It will not reliably bond to heavy woven cottons such as duck canvas — for garment or fabric interfacing, choose one of our woven or non-woven fusible interfacings instead.
To apply: place the interlining adhesive-side down on the leather cut piece and press at 105–120 °C (221–248 °F) for 7–10 seconds at 4–6 kg/cm² (50–60 psi). Let it cool to set.
