Polyether Polyols For Flexible Foams 1. Description Regular activity polyether polyols are suitable for manufacturing
flexible polyurethane foams such as furniture pads, mattresses,
sound-absorbing board, carpeting substrates, filters. When foams
are produced, the amount of the additives is variable and
adjustable in a wide range. They also have good stability during
foaming; High activity polyether polyols can react with an amount
of isocyanates to give reaction injection molding(RIM) polyurethane
products. The cold cured and high resilient products made of the high
activity polyether polyols, such as cushions of automobile and
transport means, steering wheels, dash-board and handles etc, and
furniture, have good resilience, compression subsidence and
comfortable feeling. 2.
