Regular polyurethane (PU) leather undergoes chemical chain scission in high-humidity environments, leading to surface peeling and structural degradation within 1-2 years. Microfiber synthetic leather solves this chemical instability by integrating polyether-based resins within a three-dimensional sea-island non-woven matrix, achieving an engineered lifespan of 3-5 years and passing >Izu 5 n'ime ule oke ọhịa ahaziri (ogo 70, 95% RH).
