17、3.2.3 open cell foama foam made porous by interconnect-ing cells.4. Classification4.1 The flexible polymeric insulations of this specificationare classified into Types I and II. Type I is a closed flexiblefoam. Type II is an open cell flexible foam.NOTE 1The primary difference between Type I and Typ
18、e II materialsare: Type I materials exhibit lower water absorption properties and TypeII materials have greater acoustical properties as noted in Tables 1 and 2.5. Materials5.1 These products shall be made of a homogeneous blendof natural or synthetic polymeric materials. Modifications withvarious t
19、hermoplastic or thermosetting resins, plasticizers,modifiers, antioxidants, curatives, blowing agents and otheradditives are allowed. These products do not melt whenexposed to heat and are considered to be thermoset materials.5.2 Flexible, polymeric cellular thermal insulations shall beof uniform co
20、re density. These insulation materials are avail-able with a smooth skin surface or coating on one or both sides,and they are to be considered homogeneous for the purposes ofdetermining thermal performance.6.
