簡単な説明：

WynPUF® is our brand for polyurethane foam additives. XH-2900 and XH-2908 are used in MDI based viscoelastic PU system as dual surfactant. XH-2900 provides foam with closed tight cell structure, increasing the foam’s crosslinking density, on the other hand, XH-2908 provides foam with opened and fine cell structure, adjusting the amount of these two surfactants, we can easily get the foam with very fine cell structure and very low compression set.
