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 195C for 48 hours and/or a flammability rating of V-1 or V-0 at 0.5 inch according to Underwriters Laboratories Standard 94 Vertical Flammability Test (UL 94).

A first oriented film comprising a first polyethylene composition which comprises: from20 to 50wt% of a first linear low density polyethylene polymer having a density greater than 0.925g/cc and an I2 lower than 2g/10 min; and from 80 to 50wt% of a second linear low density polyethylene polymer having a density lower than or equal to 0.925g/cc and an I2 greater than or equal to 2g/10min; wherein the first polyethylene composition has an I2 from 0.5 to 10g/10min and a density from 0.910 to 0.940g/cc is provided.


A storage stable isocyanate-reactive composition has ethylene oxide content from 1 wt% to 50 wt%, based on the total weight of an isocyanate-reactive component that includes a polyol component, a catalyst component, and a blowing agent component. The polyol component includes at least one polyol, the catalyst component includes at least one amine catalyst, and the blowing agent component includes at least one hydrohaloolefin based blowing agent. The isocyanate-reactive component is storable at least at one of room temperature and a higher temperature for a period of at least 1 day with a less than 10 second change in gel time when reacted with an isocyanate component at an isocyanate index from 100 to 150, compared to when the same isocyanate-reactive component is stored for a period of less than 1 day at room temperature and reacted with the same isocyanate component at the same isocyanate index from 100 to 150.
