Door And Window Sealing Strips - China
price: contact company for price
The core function of door and window sealing strips is to fill the gaps between the door and window frame and sash, and between the glass and the profile.
They also need to be adaptable to conditions such as frequent opening and closing of doors and windows, changes in outdoor temperature and humidity, and exposure to sun and rain.
Tolerance to extreme temperature fluctuations: Resistant to -40℃~60℃ in frigid northern regions and -20℃~80℃ in hot southern regions.
No brittleness at low temperatures (embrittlement temperature ≤ -50℃) and no softening or deformation at high temperatures (heat distortion temperature ≥ 70℃).
Elastic recovery rate ≥ 80% after long-term use (over 10 years).
Excellent anti-aging performance: Resistant to ultraviolet (UV) radiation, ozone (vehicle exhaust/atmospheric ozone), and rainwater erosion.
After 5000 hours of outdoor exposure, standard EPDM strips retain ≥70% of their tensile strength, with no significant cracking or discoloration (as required by national standard GB/T 12002-2016).
