Silicone sealing strips are elastic sealing elements manufactured from silicone rubber via extrusion, moulding and other processes. Thanks to their excellent overall performance, they are widely used in households, machinery, automobiles, doors, windows and other fields.
Core Performance Features
Extremely wide temperature resistance range The standard operating temperature ranges from -50℃ to 200℃. Special formulations can achieve a range of -70℃ to 300℃. It will not soften at high temperatures nor become hard and brittle at low temperatures, maintaining stable performance during long-term service. Weather resistance and anti-aging property It features excellent resistance to ozone, ultraviolet rays, wind and rain. It will not crack, fade or pulverize after long-term outdoor use, with a far longer service life than ordinary rubber products. High elasticity and resilience
It has low compression set. It can rebound rapidly after repeated compression and bending, retaining stable sealing force for a long time, and is ideal for frequently opened and closed applications.
Common Structural Types
Solid sealing strip: High density and great strength, suitable for mechanical sealing, buffering and pressure-bearing scenarios. Foamed sealing strip: Lightweight and soft, with superior heat and sound insulation, applied to doors, windows, home appliances and lightweight sealing. Special-shaped / Composite sealing strip: Customized into various profiles (U-type, E-type, P-type, double-square shape, hollow-square shape, etc.) to fit complex gaps. Self-adhesive sealing strip: Equipped with high-temperature resistant adhesive backing for direct installation, easy and convenient to use.
Main Application Fields
Architectural doors and windows, home appliances, automotive transportation, industrial machinery, bathroom and home decoration.
Product Advantages
Comprehensive performance: Integrates temperature resistance, weather resistance, elasticity, environmental friendliness and waterproof performance. Long service life: Runs stably for a long time in harsh environments, reducing replacement frequency and maintenance costs. High adaptability: Customizable in color, hardness, density, cross-section and length to meet diverse equipment requirements.
