English English العربية العربية Português Português

YISHAN Chemicals has been researching, manufacturing, and selling PU resins since 1995. As the first ISO9001 certified PU resin manufacturer in domestic China, we are able to offer you a full range of PU resins, including wet-process PU resins, dry-process PU resins, PU resins for fabric coating, resins for surfaces, resins for bonding layers, resins for surface treatments, etc. Our PU resins come in a great variety. They vary in terms of their flexibility, drying speed, heat and cold resistance, bonding strength, peeling strength, tensile strength, rigidity, etc., and are widely used for high quality applications in the manufacturing of clothing leather, bag leather, sofa leather, shoe leather, ball leather and other industries. In addition, chemicals, like cross-linking agents and accelerants, are also available.

  • Wet Process PU Resin
  • Wet Process PU ResinWet process PU resin is produced by adding DMF solvents and other additives to the raw resin. The obtained mixture is then deaerated by a vacuum machine and dipped or coated to the base fabric. It is then immersed into water, which has affinity to solvent (DMF) and does not have affinity to PU resins. After the solvent (DMF) is replaced by water, the PU resin congeals gradually and a porous involucra is formed. ...
  • Dry Process PU Resin
  • Dry Process PU ResinDry process PU resin is made by smearing PU resin on release papers with different patterns. It is then dried and adhered with base fabrics (knitted fabric, non-woven fabric). After drying, the patterns on the PU resin are almost the same as those on the release paper. It is then printed to be similar with dermis in terms of its hand feel, flexibility, and appearance. ...

  • Dry Process PU Resin for Fabric Coating
  • Dry Process PU Resin for Fabric CoatingFabric coating is a process of adding coating material to the surface of the fabric. In a broad sense, fabric coating also includes lamination, which means adding bonding agent to the base fabric and have it coated with a film or other materials to form a composite textile after it is heated and pressed. Various kinds of coating agents are now available. Among these coating agents, the most common ones are latex, PU resin, polyacrylic ester, polyethylene and more ...
  • Agent and Accelerant
  • Agent and AccelerantAccelerant, abbreviation of vulcanizing accelerant, is used to accelerate vulcanization. It shortens the time of vulcanization, reduces the vulcanizing agent required, and improves the physical and mechanical performance of the rubber. Accelerant falls into two categories: organic accelerator and inorganic accelerator. Currently, organic accelerator is the most used. ...
