Classification4.1 The
20、 flexible polymeric insulations of this specification are classified into Types I and II. Type I is a closed cell flexible foam.Type II is an open cell flexible foam. Type II is further divided into Grades A and B differentiated by the flame spread/smokedeveloped indices.NOTE 1The primary difference
21、 between Type I and Type II materials are: Type I materials exhibit lower water absorption properties and Type IImaterials have greater acoustical properties as noted in Tables 1 and 2.5. Materials5.1 These products shall be made of a homogeneous blend of natural or synthetic polymeric materials. Mo
22、difications withvarious thermoplastic or thermosetting resins, plasticizers, modifiers, antioxidants, curatives, blowing agents and other additivesare allowed. These products do not melt when exposed to heat and are considered to be thermoset materials.5.2 Flexible, polymeric cellular thermal insula
