I-ECO brand PU-coated sealing strip which contains a special sound-absorbing cotton, the effective absorption of the active window into the interior of some of the leakage noise, more noise performance than conventional sealing tape, can improve performance by 35% soundproof windows. The new seal is durable, not shrink, stability, strong elasticity, can maintain the original shape unchanged after many years, to ensure the sealing performance of the product, the service life of up to 20 years. ? I-ECO brand products as environmentally friendly products that do not contain CFC harmful substances. And does not react with any paint, cleaning agents, customers do not need to worry about the integrity and appearance of windows and doors were damaged. Sheathed seal parameters: 1, compression test: at 70 ℃, 50% compression rate continues to compress 22 hours, deformation rate ≤10% 2, the compression force test: at 25% compression rate, to impose 15N / 100mm of force, the compression ratio ≤10N. 3, the temperature range of the test: from -40 ℃ to 90 ℃, sealing performance with no significant change in test 4. The thermal conductivity K value: K value at 0 ℃ ≤0.035W / m2K. 4, thermal conductivity K value of the test: K values ??0 ℃ ≤0.035W / m2K. 5, resistance to fatigue testing: mimic the shape of the window switch 50 million times without significant change. 6, insulation resistance test: IV68 windows with only strip down the middle of noisy 43 db IV76 windows with intermediate strips and an additional strip of noisy down 45 points. 7, outdoor anti-aging test: currently has more than 20 years of performance remains intact product features advanced engineering with polyethylene outer envelope, good corrosion resistance and paint migration and glamorous look. 8, anti-UV (ultraviolet), resistant to sunlight and UV 5000Kj / m, no erosion. High elasticity foamed polyurethane material openings, long time to maintain the shape and high elastic temperature range -40 ℃ to 70 ℃.
