17、ls.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 Type II materialsare: Type I materials exhibit lower water absorp
18、tion 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 thermoplastic or thermosetting resins, plasticizers,modifiers,
19、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 core density. These insulation materials are avail-able with a s
20、mooth skin surface or coating on one or both sides,and they are to be considered homogeneous for the purposes ofdetermining thermal performance.6. Ordering Information6.1 Specific installation, insulation type, thickness, length,and width suited for the intended use shall be agreed upon bythe purcha
21、ser and supplier.7. Physical PropertiesSee Tables 1 and 2 for Summaryof Requirements7.1 Apparent Thermal ConductivityThe material shall betested for apparent thermal conductivity at 75F (24C) meantemperature in accordance with 12.1. The thermal conductivityfor the average of any four randomly select
22、ed samples, shallnot be more than 0.30 Btu-in./h-sq ftF (0.043 W/m-K) whentested in accordance with 12.1. See Table 1.NOTE 2Consult the local or state building codes for the minimuminstalled thermal resistance, R-value, required to be installed.7.2 Surface Burning CharacteristicsShall be in accor-da

24、Table 1.NOTE 3Hot Surface Performance Characteristics for Type 1MaterialWhen this type of material is used on hot applications, thematerials characteristics will change and should be considered whenselecting the material for an application. Heat will cause the elastomericinsulation to harden. As the
25、 temperature approaches the stated hightemperature limit, the process occurs faster. This hardening will notnegatively effect the thermal performance or water vapor transmissionproperties of the product. The hardening will be most noticeable closer tothe heat source. This effect is based on time and
