PU coated door and window seals have the advantages of anti-collision, sound insulation, insect prevention, windproof, light insulation, smoke insulation, waterproof, as well as long service life and excellent performance.
The characteristics and advantages of PU coated door and window seals are mainly reflected in the following aspects:
Versatility: PU coated door and window seals can effectively prevent collision, sound insulation, insect entry, wind, light insulation, smoke insulation, and have good waterproof performance.
Good sealing performance: It can effectively block the penetration of air, water, dust, etc., reduce indoor and outdoor heat exchange, play a good role in thermal insulation, and help reduce energy consumption. For example, it can reduce indoor heat loss in winter and prevent outdoor heat from entering in summer, thereby maintaining indoor temperature stability and saving energy consumption for air conditioning or heating.
Excellent sound insulation effect: It can absorb and block external noise, create a quiet environment for the room, and improve the comfort of life and work. Compared with ordinary sealing strips, the sound insulation performance is more prominent, which can effectively reduce the volume of noise entering the room.
Strong resilience: It can quickly return to its original shape after being compressed. Even when doors and windows are frequently opened and closed, it is not easy to deform and always maintains a good sealing effect.
Durability: This sealing strip can maintain stable performance and a long service life in different environments. It has anti-aging and wear-resistant characteristics, and its service life can reach 20 years.
Performance test: After rigorous performance tests, including compression deformation test, compression force test, temperature range test, thermal conductivity K value test, fatigue resistance test and sound insulation test, PU coated door and window sealing strips have performed well. For example, at 70ºC, the compression rate of 50% is continuously compressed for 22 hours, and the deformation rate is ≤10%; at a compression rate of 25%, a force of 15N/100mm is applied, and the compression rate is ≤10N; the sealing performance does not change significantly from -40ºC to 90ºC; the K value is ≤0.035W/m2K at 0ºC; the window opening and closing is simulated 500,000 times, and the shape does not change significantly; the window with the middle rubber strip and the additional rubber strip can reduce the noise by up to 45 decibels; the outdoor aging test has reached more than 20 years, and the performance remains intact.
Wide application field: PU coated door and window sealing strips are widely used in high-end doors and windows and other fields due to their excellent performance, providing efficient sealing and protection functions while maintaining good aesthetics and durability.
In summary, PU coated door and window sealing strips have become an ideal choice for high-end doors and windows with their versatility, durability and excellent performance test results.
