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). Glass sealing strip: Embedded in the glass groove to prevent glass movement and rainwater seepage.

The core function of tunnel sealing strips is to solve the waterproofing and seepage prevention problems of tunnel structures (such as shield tunnel segments and lining joints). They must also adapt to complex tunnel conditions (such as structural settlement, vibration, and corrosive environments). Their performance characteristics revolve around "sealing reliability, environmental adaptability, and structural compatibility." High seepage resistance and waterproofing: They must withstand the pressure of groundwater in the tunnel (typically 0.3- 1.0 MPa, reaching over 1.5 MPa in special geological conditions). After the strip adheres to the segment/lining joints, it forms a "continuous sealing barrier," preventing groundwater and sediment from seeping into the tunnel interior. Most use either "water-swellable" or "elastic compression" designs: water- swellable strips can absorb water and expand (expansion ratio 150%-300%) to fill tiny gaps, while elastic strips achieve long-term sealing through structural compression. In some scenarios, both types are used in combination. In tunnel environments that are chronically humid and lack sunlight (or have weak lighting), the strips must be resistant to... "Damp heat aging" and "ozone aging" (vehicle exhaust contains ozone) are required, with a standard service life of ≥20 years (matching the tunnel structure's design life). After aging, tensile strength retention should be ≥70%, and elastic recovery rate ≥80%. UV resistance does not need to be excessively high (UV radiation is weak inside tunnels), but it must withstand temperature fluctuations (-30℃~60℃, down to -40℃ in frigid northern regions), without becoming brittle at low temperatures or softening and deforming at high temperatures.

The sealing gasket in plate heat exchangers primarily serves to seal between hot and cold media. 1. Possesses excellent elasticity and compression recovery, tightly conforming to the sealing groove of the plate after compression to block medium leakage and accommodate pressure demands under various operating conditions. 2. Withstands temperatures ranging from -50°C to 200°C or broader depending on material composition, adapting to thermal fluctuations during hot/cold medium exchange without brittleness or softening. 3. Resists swelling and aging from common heat transfer media like water, oil, and acid/alkali solutions. Does not react chemically with media, maintaining stable performance. 4. Resists tearing, abrasion, and compression set. Maintains original shape and sealing performance after prolonged exposure to plate compression and media erosion, extending service life. 5. Manufactured with high precision and low thermal expansion coefficient. Minimizes deformation post-installation, ensuring accurate fit with plate sealing grooves and simplifying installation.
