Our Story
In 1998, we began envisioning a new synthetic leather system through R&D in water-based PU (waterborne PU). This marked our first step to reimagine a PU leather solution completely different from our preexisting method, a method based on the organic solvent dimethylformamide (DMF or DMFA, CAS No. 68-12-2). Traditionally and at that time, most manufacturers delivered PU leather through a DMF solvent-based system. In that system, PU leather’s production method and raw material both used DMF; the PU leather produced was called wet PU or wet-process PU (though called “wet process,” it’s not to be confused with water-based PU which uses no DMF; see FAQ and PU Knowledge→Water-Based PU V.S. Solvent-Based PU).

In 2005, to widen our solution spectrum while maintaining a green approach, we initiated R&D in a solvent-free polyurethane system we named prepolymer PU, or PPU (see DMF-Free Eco PU Solutions→Solvent-Free Prepolymer Polyurethane). In the non-solvent PPU system, we have eliminated DMF and water altogether, giving PPU resin close to 100% PU solid content and higher molecular weight than water-based PU and traditional solvent-based PU, enabling our non-solvent PPU leather to achieve more extreme physical performances. In 2008, we succeeded in our first scaled-up production. With PPU in our repertoire, we can offer PU leather with higher rebound resilience, toughness, flexing resistance, coating adhesion, and firmness. PPU can meet demands for durable upholstery, automotive use, hockey skates, and patent PU leather with no creases. PPU has also significantly reduced the VOC, energy & water consumption, greenhouse gas & CO2 emission, and harmful substances used, with almost no industrial wastewater in PPU leather production.
