Classification4.1 The flexible polymeric insulations
17、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 absorption properties and TypeII materials have greater acoustica
18、l 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, antioxidants, curatives, blowing agents and otheradditives
19、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 smooth skin surface or coating on one or both sides,and they
20、 are to be considered homogeneous for the purposes ofdetermining thermal performance.6.

24、ype 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 temperature approaches the stated hightemperature limit, t
25、he 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 temperature.7.4 Water Vapor SorptionShall be tested in acc
