Custom Extruded Solid Silicone Rubber Strip High Temperature Waterproof Sealing Strip Gasket for Door Window

Welcome to Rubrisil, where we specialize in manufacturing high-performance extruded silicone rubber strips. This product is not a simple filler material but a precisely engineered solution designed to provide lasting and reliable sealing, insulation, cushioning, and protection across various industries. Thanks to its exceptional physical and chemical stability, our silicone strip maintains superior performance under extreme temperatures, chemical exposure, and long-term mechanical stress, making it a key component for enhancing your product's quality and durability.

Key Features & Core Advantages

• 1. Extreme Weather & Temperature Resistance:
  Our silicone strips maintain stable flexibility and elasticity over a wide temperature range of -60°C to 250°C (-76°F to 482°F). Whether in scorching desert heat or freezing polar climates, they will not harden, crack, or degrade, ensuring all-weather sealing performance. Their excellent resistance to UV and ozone makes them the ideal choice for outdoor applications.

• 2. Superior Sealing & Waterproof Performance:
  The inherent hydrophobic nature of silicone makes it a perfect waterproof barrier. Our sealing strips effectively block the ingress of moisture, dust, and air, providing IP-rated protection for your equipment enclosures, window and door systems, and precision instruments.

• 3. Excellent Compression Set Resistance:
  Even after long-term compression, our silicone strips return to their original shape, which is crucial for ensuring a lasting and effective seal. This "low compression set" property means they won't "flatten" and fail like other materials, guaranteeing continuous sealing pressure.

• 4. Outstanding Electrical Insulation:
  As an excellent dielectric material, silicone strips effectively isolate electrical currents, preventing leakage and short circuits. They are widely used for insulating seals in electrical cabinets, battery packs, and electronic devices, serving as a critical line of defense for electrical safety.

• 5. Broad Chemical Compatibility:
  It withstands exposure to a wide range of chemicals, including weak acids, alkalis, detergents, and various industrial oils, allowing it to maintain its structural and functional integrity in complex chemical environments.

Core Application Areas

• Architecture & Fenestration: Used as seals for doors, windows, curtain walls, and partitions, providing excellent soundproofing, waterproofing, and energy efficiency.

• Industrial Equipment & Electrical Cabinets: Serves as door seals for enclosures and electrical cabinets, protecting sensitive internal components from dust and moisture.

• Automotive & Rail Transit: Employed for sealing doors, windows, sunroofs, and engine compartments, effectively dampening vibration and noise while providing reliable protection.

• Food Processing & Medical Devices: Food-grade silicone strips compliant with FDA standards are available for use in oven door seals, medical equipment, and cleanroom applications.

• Lighting & Outdoor Equipment: Used for waterproof sealing of LED fixtures, outdoor billboards, and communication equipment to ensure their long-term, stable operation.
