Description
Made in the USA, K-FLEX™ ECO is a halogen free, closed cell, elastomeric insulation. It is green in color, marked in gold ink, and is available in tube and sheet form. Tube sizes range from 3/8" inside diameter to 8" iron pipe size, in 1/2", 3/4" and 1" wall thickness. Sheets and rolls are available in 1/2", 3/4" and 1" thickness. K-FLEX™ ECO does not contain carbon black in accordance with United States Navy Environmental Department standards. Additionally, K-FLEX™ ECO does not contain fibers, PVC, or CFCs.
Applications
K-FLEX™ ECO was developed for applications where corrosive smoke and environmental issues (toxicity) are critical. It is suitable for piping, vessels, and ductwork, on United States Naval Ships, the general maritime industry, and other industrial applications. K-FLEX™ ECO is certified to Electric Boat Corporation Specification EB 4013 and meets the requirements specified by the International Maritime Organization, meeting IMO specifications per the SOLAS Agreement.
K-FLEX™ ECO is used to insulate hot piping up to 300°F (1" thickness minimum). It can be used as an alternative to low-temperature fiberglass, calcium silicate and polyimide insulation. K-FLEX™ ECO can be used on 50 lb. steam lines with design temperatures up to 300°F (1" thickness minimum). Used under these conditions a comparable thin layer of discolored hardened material in the inner wall will form. This does not in any way adversely affect the insulation properties of the foam.
K-FLEX™ ECO is also used on cruise ships and other commercial vessels. It is suitable for use in industrial and commercial areas like clean rooms, food and beverage manufacturing facilities where a fiber-free environment is specified.
K-FLEX™ ECO is well suited for stainless steel applications since it contains no halogens which are known to contribute to corrosion problems.
Installation
K-FLEX™ ECO is applied following the guidelines used for all Nomaco K-FLEX elastomeric insulation products. Tubing slides easily over piping, or for existing lines, tubing is slit lengthwise and snapped into place. All seams and joints should be sealed with an approved contact adhesive.
When K-FLEX™ ECO is applied to vessels and ductwork, use a 100% coverage of an approved contact adhesive. Both surfaces to be joined should be coated and then joined after the adhesive is dry to the touch. Compression joints with adhesive applied should be used on all butt edges. For detailed installation procedures, reference the Nomaco K-FLEX Insulation Installation Guide.
Resistance to Water Vapor Diffusion
The closed-cell structure and unique formulation of K-FLEX™ ECO effectively retards the flow of moisture vapor, and is considered a diffusion resistant insulation. For most applications, K-FLEX™ ECO requires no additional protection.
Additional vapor barrier protection may be necessary for K-FLEX™ ECO when installed on low temperature surfaces in combination with continuous high humidity conditions.
