White Elastomeric Insulation
K-FLEX™ LS WHITE PIPE INSULATION is designed for exposed piping areas. K-FLEX™ LS WHITE PIPE INSULATION is suitable for supermarket, hospital and school applications where a more hygienic appearance is preferred. K-FLEX™ LS WHITE PIPE INSULATION meets all K-FLEX™ LS TUBE specifications and thermal properties.
Description
K-FLEX™ LS WHITE PIPE 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. K-FLEX™ LS WHITE PIPE INSULATION key physical properties are approved through supervision by Factory Mutual Research Corporation. K-FLEX™ LS WHITE PIPE INSULATION is non-porous, non-fibrous and resists mold growth. The Bio-Guard™ antimicrobial system provides added protection against mold, fungal and bacterial growth. The active ingredient in Bio-Guard™ is registered with the EPA.
Applications
K-FLEX™ LS WHITE PIPE INSULATION is used to retard heat gain and prevent condensation or frost formation on refrigerant lines, cold water plumbing and chilled water systems. It also retards heat flow for hot water plumbing, liquid heating, dual temperature piping and many solar systems. K-FLEX™ LS WHITE PIPE INSULATION is designed for the professional contractor.
K-FLEX™ LS WHITE PIPE INSULATION is recommended for applications ranging from -70°F to 220°F (-57°C to 104°C). The expanded closed cell structure makes K-FLEX™ LS WHITE PIPE INSULATION an efficient insulator and provides effective moisture vapor resistance.
K-FLEX™ LS WHITE PIPE INSULATION 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.
Installation
With a factory-applied coating of talc on the smooth inner surface, K-FLEX™ LS WHITE PIPE INSULATION 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.
K-FLEX LS WHITE PIPE INSULATION is intented for indoor use. If used outdoors, appropriate protective coating or jacketing is required to protect it from UV and mechanical abuse.
Resistance to Moisture Vapor Flow
The closed-cell structure of K-FLEX™ LS WHITE PIPE INSULATION effectively retards the flow of moisture vapor, and is considered a low transmittance vapor retarder. For most indoor applications, K-FLEX™ LS WHITE PIPE INSULATION needs no additional protection.
Additional vapor barrier protection may be necessary for K-FLEX™ LS WHITE PIPE INSULATION when installed on low temperature surfaces that are exposed to continuous high humidity.
Flame and Smoke Rating
K-FLEX™ LS WHITE PIPE 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.” KFLEX™ LS WHITE PIPE INSULATION is acceptable for use in duct/plenum applications, 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.
