摘要: A method for making a rigid polyurethane foam by reacting a polyisocyanate and a polyol in the presence of a urethane catalyst, a blowing agent and a silicone surfactant characterized by employing a blowing agent comprising a C4 or C5 hydrocarbon, or mixtures thereof, with an average molecular weight of ≦72 g/mole and a boiling point in the range of 27.8 to 50° C., and a silicone surfactant comprising a polyether-polysiloxane copolymer represented by the following formula: (CH3)3—Si—O—(Si(CH3)2—O)x—(Si(CH3)(R)O)y—Si(CH3)3 where R=(CH2)3—O—(—CH2—CH2—O)a—(CH2—CH(CH3)—O)b—R″, and where R″ is H, (CH2)zCH3, or C(O)CH3; x+y+2 is 60–130; x/y is 5–14; z is 0–4; the total surfactant molecular weight, based on the formula, is 7000–30,000 g/mole, the wt % siloxane in the surfactant is 32–70 wt %, the blend average molecular weight (BAMW) of the polyether portion is 450–1000 g/mole, and the mole % of ethylene oxide in the polyether portion is 70–100 mole %.
