Synthetic leather has two main themes of "decomposability" and "emissions" in response to being environmentally-friendly.
  • [Decomposability]
    1. PU leather fabric is recognized as an environmentally-friendly material because it is not resistant to hydrolysis, but specially-synthesized PU leather has a hydrolysis resistance of up to 10 years, and has a relatively high price.
    2. PVC leather fabric itself is not hydrolyzed, but it can be recycled and reused.
  • [Manufacturing Emissions]
    1. General PU products emit volatile organic compounds (VOCs) as they contain solvents, but water-based and solvent-free PU products have no VOC emission issues.
    2. PVC itself does not emit VOCs, solvent-based primers contain minimal amounts of VOCs. Currently, water-based primers can overcome this issue.
