OCTOBER 2016 Page 2 of 6 4.2 Rigid Foam This specification includes two (2) types of rigid foam with two different grades available for each based on density and material properties. Type I is an unreinforced, two (2) component
11、urethane, reaction injection molded structural foam. Type II is similar except it is glass reinforced and includes two (2) grades with different glass content and density. The selection of the Type and Grade shall be made by Materials Engineering. 4.2.1 The rigid foam shall be a two component uretha

21、all requirements of FMVSS-302, Flammability of Interior Materials and all requirements of MPAPS P-9544. Components of the composite which are not 100% bonded together shall be tested separately and each component must demonstrate required flammability resistance. Components of the composite which ar
22、e 100% bonded together are not specifically required to demonstrate flammability resistance when tested as individual parts, however, the bonded (finished) composite must demonstrate required flammability resistance.
