Embodiment 1 and 2
[0099] Embodiment 1 and 2 and comparative sample A * ：
[0100] For Examples 1 and 2 and Comparative Sample A, slab foam was prepared by hand mixing according to the procedure described above for "Method A" using the component amounts shown in Table 2, where the amounts are expressed in parts per 100 Parts total polyol (PHP or PPHP) are given, otherwise specified. (For example, isocyanates are in index units).

Embodiment 3-5
[0107] Examples 3-5 use castor oil and natural oil polyols
[0108] For Examples 3-5, molded foams were prepared according to the "Method B" procedure described above, using the component amounts shown in Table 3, where the amounts are expressed in parts per 100 parts of total polyol (PHP or PPHP) is given, otherwise specified otherwise. The demoulding time was 4 minutes. Air flow was measured after breaking down the foam (breakdown of closed cells).
Embodiment 3
[0111] Examples 3, 4 and 5 show that in Example 3, the combination of NOPO-1 and NOPO-3 resulted in a foam that was difficult to release and slightly less dense than the foams of Examples 4 and 5. The quality improved due to the addition of NOPO-2 in Examples 4 and 5, and even when the amount of NOPO-3 was increased in Example 5. Embodiment 3 obtains than following comparative sample C * Higher content of renewable resources (32.3wt% natural oil), where in comparative sample C * In , there is 27.5 wt% natural oil (which results in essentially the same performance).
[0112] When in embodiment 3', 4' and 5', use the prescription of embodiment 3, 4 and 5 respectively, replace NOPO-2 with NOPO-4, difference is the consumption of NOPO-4 replacement and embodiment Similar results were obtained when the amount of NOPO-2 was the same.
