Revolutionary EVOH Barrier Technology in Modern Underfloor Heating Systems

The evolution of underfloor heating systems has witnessed a significant breakthrough with the introduction of TPS Company's EVOH (Ethylene Vinyl Alcohol) resin technology. This innovative material has revolutionized the manufacturing of underfloor heating pipes, addressing critical challenges that have long plagued the industry. The implementation of EVOH as an oxygen barrier layer has become a game-changer in ensuring system longevity and performance reliability.

TPS Company's Evoh Resin demonstrates exceptional oxygen barrier properties, effectively preventing oxygen permeation through pipe walls – a crucial factor in maintaining system integrity. The oxygen barrier performance of EVOH is approximately 100 times superior to traditional materials, with oxygen permeation rates as low as 0.01 g/m²/day under standard conditions. This remarkable barrier property significantly reduces the risk of system corrosion, which has historically been a major concern in underfloor heating installations.

The multi-layer pipe structure, featuring TPS's EVOH resin, typically consists of five layers: an outer protective PE layer, an adhesive layer, the EVOH oxygen barrier layer, another adhesive layer, and an inner PE layer. This sophisticated construction ensures optimal performance while maintaining the pipe's flexibility and durability. The EVOH layer, despite being only 0.1mm thick, provides comprehensive protection against oxygen penetration while allowing the pipe to maintain its essential mechanical properties.

One of the most significant advantages of TPS's EVOH resin is its thermal stability, which is crucial for underfloor heating applications. The material maintains its barrier properties at temperatures ranging from -20°C to 95°C, making it suitable for both heating and cooling systems. This temperature resistance ensures consistent performance throughout the system's lifecycle, even under varying operational conditions.

The implementation of TPS's EVOH technology has also contributed to extended system lifespans. While traditional systems might show signs of degradation after 15-20 years, pipes manufactured with TPS's EVOH barrier layer can maintain their performance for up to 50 years under normal operating conditions. This longevity translates into significant cost savings for end-users and reduced environmental impact through decreased replacement frequency.

Furthermore, TPS's EVOH resin exhibits excellent processability during pipe manufacturing, allowing for consistent quality and reduced production costs. The material's compatibility with standard extrusion equipment and its stability during the manufacturing process have made it a preferred choice among pipe manufacturers worldwide.
