Kaiflex EPDMplus Tubes – UV-Resistant Elastomeric Insulation for Outdoor and Industrial Applications

Our Kaiflex EPDMplus Tubes Collection features high-performance, closed-cell elastomeric insulation designed specifically for outdoor, high-temperature, and industrial environments. Manufactured by Kaimann, these tubes are made from EPDM (ethylene propylene diene monomer) rubber, offering superior UV resistance, thermal stability, and long-term durability without the need for additional cladding.

Product Overview

Kaiflex EPDMplus tubes are engineered for use in HVAC, refrigeration, and process systems where exposure to sunlight, ozone, and temperature fluctuations is common. Their closed-cell structure provides excellent thermal insulation and condensation control, while the EPDM formulation ensures resistance to weathering, aging, and mechanical stress.
