With over 20 years of industry experience and a modern facility in Xiong County, Hebei Province, China, we combine advanced production technology with rigorous quality control to deliver consistent excellence.

Advanced Material Technology

Butyl tape for windows is formulated with high-purity butyl rubber (content ≥98%), combined with specialized tackifying resins and stabilizers. It is solvent-free and ultra-low VOC (<0.5 g/L), fully compliant with EU REACH and US ASTM environmental standards.

The tape provides extremely strong adhesion to glass, aluminum, PVC, wood, and composite substrates: initial peel strength tested per ASTM D3330 reaches ≥18 N/cm and stabilizes above 25 N/cm after 24 hours. With elongation exceeding 400%, it easily accommodates ±15 mm of thermal expansion and contraction.

The product operates in a wide temperature range of -40°C to +120°C and demonstrates outstanding weather resistance—passing 5000 hours of QUV accelerated aging with zero cracking or chalking. Its water vapor transmission rate is <0.05 g/m²/24h, along with excellent resistance to acids, alkalis, and chemicals, ensuring reliable sealing performance for over 30 years.
