- Resistance to Moisture Vapor Flow
The expanded closed cell structure and unique formulation inherently resists moisture vapor intrusion. For most indoor applications, K-FLEX® ECO® needs no additional protection. Additional vapor barrier protection may be necessary when installed on cold surfaces that are exposed to continuous high humidity

- Applications
K-FLEX® ECO® is recommended for applications with service temperatures ranging from -297°F (-182°C) to +250°F (+120°C). For applications below -40°F (-40°C), contact K-FLEX® technical support. When using factory-applied PSA, the low temperature limit is -40°F (-40°C). When the product is installed fully adhered to the insulated surface (via contact adhesive or PSA), the high temperature limit is +200°F (+93°C).The product is used to retard heat gain and prevent condensation or frost formation on below ambient applications, including refrigerant, cold water plumbing, chilled water, and industrial process lines, among others. It can be used with heat tracing tapes. It also retards heat loss from medium hot systems, including hot water plumbing, liquid heating, dual temperature, and solar thermal piping, among others. K-FLEX® ECO® is designed for applications where corrosive smoke and environmental issues (toxicity) are critical, including US Naval Ship and other general maritime applications. It is well-suited for stainless steel applications, notably those with service temperatures above 90°F, as it does not contain halogens that are known to contribute to corrosion. Under high operating temperature conditions (i.e. 250°F), a thin layer of discolored hardened material in the inner wall will form. This constitutes a normal reaction and does not in any way adversely affect the insulation properties of the foam.
Outdoor Applications: K-FLEX® ECO® is made from a UV-resistant elastomeric blend. For severe UV exposure (topside applications) or for optimum performance, K-FLEX® 374 Protective Coating, approved jacketing or K-FLEX® CLAD® is recommended.
- Installation
K-FLEX® ECO® is flexible (even at low temperatures), durable (non-fracturing and skin is resistant to tearing from handling and environment), safe to handle (non-dusting and non-abrasive), and lightweight for an efficient installation. K-FLEX® recommends that insulation is installed on non-operational systems with clean, dry surfaces in ambient conditions between 40°F and 100°F. Properly sized insulation tubing can be slid over piping (tubing should be pushed, not pulled) or, when applied to existing lines, can be slit lengthwise (using a sharp, nonserrated knife) and fitted into place. All seams, butt joints, termination points and open ends should be sealed with an approved contact adhesive, making sure both surfaces to be joined are coated. Longitudinal seams should face downward and vapor stops should be installed as needed. Properly sized insulation sheets can be installed onto large OD round surfaces or flat surfaces. For round surfaces (piping or ductwork), the sheet should be wrapped (without stretching the insulation) around the pipe and sealed at the longitudinal seam with an approved contact adhesive. For ductwork and equipment, 100% coverage of an approved contact adhesive should be used, making sure to coat both surfaces. Compression joints should be used on all butt edges. Fittings (elbows, tees) and special parts (flanges, valves, etc.) can be field-fabricated from insulation tubes and sheets or K-Fit® factory-fabricated fittings can be used.

Technical Details & Test Data
- Flame and Smoke Rating
K-FLEX® ECO® in wall thicknesses of 3/4” and below has a flame spread rating of 25 or less and a smoke development rating of 50 or less as tested to ASTM E84, “Surface Burning Characteristics of Building Materials”. 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.
