Platinum-cured silicone sealing strips offer excellent resistance to high and low temperatures, UV radiation, and oxidative aging. These strips feature an attractive, decorative appearance with vibrant colors; they can be custom-colored—such as gold, silver, bronze, or green—to match door frames
Compared to traditional peroxide-cured silicone, platinum-cured silicone utilizes ultra-high-purity base rubber, significantly enhancing physical properties and maintaining superior sealing performance over extended periods. They are suitable for long-term use across a temperature range of -60°C to 240°C (with custom options available for -70°C to 350°C), greatly expanding application possibilities in construction and significantly extending service life
Odorless at ambient, high, and low temperatures and resistant to mold, these strips meet various domestic and international VOC standards and are fully compatible with the vast majority of global silicone sealant brands, making them the premier choice for high-end architectural sealing applications
Composite Sealing Strips: Material + Structure + Coating
Material Options: Platinum-cured silicone, EPDM, TPV, flexible PVC
Structural Options: Reinforced strips (with embedded cord), sponge/solid composite, multi-color composite, rigid/flexible composite, and fully encapsulated/injected strips (for sound insulation and high elasticity)
Special Surface Coatings: Wear-resistant coating; PTFE (ultra-low friction coefficient); UV-modified (enhanced scratch and wear resistance); Matte finish (excellent "skin-feel" texture, dust-repellent, and easy to clean)
Note: Options include quad-composite structures combined with advanced surface coating technologies
Lianheqiang’s exclusively developed platinum-cured silicone sealing strips—featuring a skin-friendly, dust-repellent finish—represent a breakthrough in domestic technology. Leading industry trends with superior performance and curtain-wall-grade quality, they are the ideal next-generation upgrade to replace traditional EPDM sealing strips in high-end window and door systems
