    • The present invention relates to a reactive formulation used to make a heat and flame resistant flexible polyurethane foam which is particularly suited for use in under the hood vehicle applications which require sound deadening and vibration management and a process to make said foam. Said foam is particularly suitable for such applications because desirable heat and flame resistant properties are achieved after exposure to heat over an extended period of time. In particular, the heat and flame resistant flexible polyurethane foam is made from a reactive formulation comprising an A side comprising (i) one or more organic isocyanate and a B side comprising (ii) one or more isocyanate-reactive component, (iii) a flame retardant component comprising a combination of an alkyl substituted aryl phosphate and/or an alkyl phosphate ester, and/or mixtures thereof and expandable graphite, wherein the flame retardant component is halogen- free and does not contain ammonium polyphosphate and/or red phosphorus; and (iv) one or more additional component selected from a catalyst, a blowing agent, a cell opener, a surfactant, a crosslinker, a chain extender, a filler, a colorant, a pigment, an antistatic agent, reinforcing fibers, an antioxidant, a preservative, or an acid scavenger wherein said heat and flame resistant flexible polyurethane foam made from the reactive formulation is characterized by having less than a 15 percent weight loss when heated at 195°C for 48 hours and/or a flammability rating of V-1 or V-0 at 0.5 inch according to Underwriter's Laboratories Standard 94 Vertical Flammability Test (UL 94).
    • 本发明涉及一种用于制造耐热和阻燃的柔性聚氨酯泡沫的反应性制剂,其特别适用于需要隔音和振动管理的罩罩车辆应用以及制造所述泡沫的方法。 所述泡沫特别适用于这种应用,因为在长时间暴露于热量之后实现期望的耐热和阻燃性能。 特别地,耐热和阻燃柔性聚氨酯泡沫由包含(i)一种或多种有机异氰酸酯和B侧的反应性制剂制成,所述A侧包含(ii)一种或多种异氰酸酯反应性组分,(iii) 阻燃组分,其包含烷基取代的芳基磷酸酯和/或烷基磷酸酯,和/或其混合物和可膨胀石墨的组合,其中所述阻燃组分是无卤素且不含多磷酸铵和/或红磷; 和(iv)选自催化剂,发泡剂,开孔剂,表面活性剂,交联剂,扩链剂,填料,着色剂,颜料,抗静电剂,增强纤维,抗氧化剂中的一种或多种另外的组分 ,防腐剂或酸清除剂,其中由反应性制剂制成的所述耐热和阻燃柔性聚氨酯泡沫的特征在于在195℃下加热48小时和/或可燃性等级为V时具有小于15%的重量损失 -1或V-0,0.5英寸,根据Underwriter's Laboratories Standard 94 Vertical Flammability Test(UL 94)。
