K-FLEX TITAN
K-FLEX TITAN is a flexible, co-extruded jacketed composite insulation designed to provide high durability and weather resistance for outdoor piping systems. It combines a closed-cell elastomeric foam core with a factory-applied polymeric jacket, eliminating the need for additional protective coatings or field-applied jacketing.
Key Features and Benefits:
- Superior Weather Resistance: Provides excellent UV protection and resists damage from rain and extreme temperatures without the need for field-applied paint or cladding.
- Mechanical Durability: The proprietary copolymer jacket protects against mechanical abuse, including incidental impacts from lawn equipment like weed whackers.
- One-Step Installation: Designed for quick application, the material is highly flexible and can be “pushed, pulled, or yanked through walls” without tearing.
- Thermal Efficiency: Features a low thermal conductivity and an expanded closed-cell structure that inherently resists moisture vapor intrusion, preventing condensation and energy loss.
- Code Compliance: Meets 2012–2021 IECC residential and commercial code requirements for outdoor exposure and carries an ASTM E84 25/50 fire rating (up to 1″ thickness).
Common Applications:
- HVAC Linesets: Ideal for protecting outdoor refrigerant lines in residential and commercial systems.
- VRF Systems: Rated for continuous service temperatures up to 220°F (104°C) with spikes up to 250°F (121°C), meeting the requirements of Variable Refrigerant Flow (VRF) specifications.
- Direct Burial: Can be used in direct burial applications if the lines are above the water table and installed within a PVC conduit to prevent compaction.
- Flexible Hose Protection: Used to enhance the weather and abuse resistance of various flexible hose applications.
Technical Specifications:
According to official product data from kflex.com:
- Temperature Range: Standard K-FLEX TITAN is rated from -70°F (-57°C) up to +220°F (+104°C).
- Vapor Permeability: The jacket material has a vapor permeance of ≤0.05 perms, acting as a Class I vapor retarder.
- UV Resistance: Successfully tested to 5,000 hours under ASTM G154 artificial aging with no deterioration to the surface condition.
