Ningbo Zhonggao Rubber & Plastic Manufacturing Co., Ltd. is one of the most reliable manufacturers and suppliers of facade rubber seals in China. The company has world-leading production equipment and strong manufacturing capabilities. Welcome to wholesale custom made facade rubber seals from our factory.
Material Properties
Super strong weather resistance and wide temperature adaptability
• The main material is EPDM (ethylene propylene diene monomer rubber);
• Withstands extreme temperature differences from -50°C to +150°C;
• UV resistance reaches ASTM G154 for 3000 hours without cracking;
• Suitable for buildings in polar to equatorial climate zones.
Anti-compression permanent deformation
• Compression permanent deformation rate (70℃×24h) ≤12%;
• Resilience rate is still ≥85% after 10 years of simulated aging test;
• Ensure the sealing reliability of building joints throughout the life cycle.
Multi-cavity mechanical design
• The honeycomb or dovetail cross-section structure disperses the wind pressure load to 6-8 independent air chambers;
• The wind pressure resistance level reaches ASTM E330 6000Pa;
• At the same time, it reduces the cold bridge effect by 50%.
Fireproof and environmental certification
• The optional flame retardant formula passes the EN 13501-1 B-s1,d0 standard, is halogen-free, has low VOC emissions, and meets LEED and WELL green building certification requirements.
Self-cleaning and anti-pollution
• Nano-hydrophobic coating added to the surface;
• Contact angle ≥ 110°;
• Stain adhesion rate reduced by 70%;
• Reduced curtain wall maintenance costs.
Lightweight and installation adaptability
• Density 1.2-1.5g/cm³, 60% lighter than metal sealing strips;
• Supports snap-on, adhesive or embedded installation, suitable for aluminum profiles, glass and concrete substrates.
Application Scenarios and Advantages
Glass curtain wall
The multi-cavity structure realizes triple protection of airtightness/watertightness/soundproofing, and dynamically compensates for ±12mm structural displacement.
01
Metal roof
Acid and alkali corrosion resistance and wind-resistant performance, suitable for coastal high-salt fog industrial plants.
02
BIPV photovoltaic building
EPDM material can withstand 200℃ photovoltaic panel back temperature, ensuring 30-year sealing life.
03
Prefabricated building
Pre-buried sealing strips and PC components are produced simultaneously, shortening the on-site construction period by 40%.
04
Transportation hub
Flame-retardant formula + earthquake-resistant design, meeting the fire protection and safety standards of airports and high-speed railway stations.
05
