Products > FlexTherm White Elastomeric Insulation FlexTherm® White is designed for exposed piping areas. FlexTherm® White is suitable for supermarket, hospital and school applications where a more hygienic appearance is preferred. FlexTherm® White meets all FlexTherm® Pipe Insulation specifications and thermal properties. DescriptionFlexTherm® White tubular insulation is an environmentally friendly, CFC-free, flexible elastomeric thermal insulation. It is white in color, and is available in unslit tubular form in wall thicknesses of 1/2", 3/4" and 1" in sizes ranging from 3/8" I.D. to 4 1/8" I.D. FlexTherm® White is non-porous, non-fibrous and resists mold growth. Applications
FlexTherm® White is recommended for applications ranging from -70°F to 220°F (-57°C to 104°C). The expanded closed cell structure makes FlexTherm® White an efficient insulator and provides effective moisture vapor resistance. FlexTherm® White has a very tough skin which withstands tearing, rough handling, and severe environmental conditions, and yet is quite flexible for easy installation. Its white color allows it to be covered easily with a white coating. InstallationWith a factory-applied coating of talc on the smooth inner surface, FlexTherm® White slides easily over pipe or tubing for quick installation. When applied to existing lines, tubing is slit lengthwise and fitted into place. All seams and butt joints should be sealed with an approved contact adhesive, making sure both surfaces to be joined are coated with adhesive. FlexTherm White is intended for indoor use. If used outdoors, protective coating or jacketing is required to protect is from UV and mechanical abuse Resistance to Moisture Vapor FlowThe closed-cell structure of FlexTherm® White effectively retards the flow of moisture vapor, and is considered a low transmittance vapor retarder. For most indoor applications, FlexTherm® White needs no additional protection. Additional vapor barrier protection may be necessary for FlexTherm® White when installed on low temperature surfaces that are exposed to continuous high humidity. Flame and Smoke RatingFlexTherm® White Tubular Insulation in wall thicknesses of 1" (25 mm) and below has a flame spread rating of 25 or less and a smoke development rating of 50 or less as tested by ASTM E 84 Method of Testing entitled: “Surface Burning Characteristics of Building Materials.” FlexTherm® White is acceptable for use in duct/plenum application, meeting the requirements of NFPA 90A/B. Numerical flammability ratings alone may not define the performance of products under actual fire conditions. They are provided only for use in the selection of products to meet limits specified, when compared to a known standard. Specification ComplianceASTM C 534 Type 1 (Tubing), Grade 1 ASTM E 84 1-1/2" 25/50-tested according to UL 723 and NFPA 255 NFPA No. 101 Class A Rating NFPA 90A Sect. 2.3.3 for Supplementary Materials for Air Distribution System.
