Dustproof Bellows Seal

Door & Window Sealing

Installed along the edges between door/window frames and panels to create dust and sound barriers, minimizing the entry of external dust, rain, and environmental noise (e.g., sliding doors, casement windows, curtain wall joints).

Wall & Floor Joint Sealing

Filling structural joints (e.g., expansion joints, settlement joints) to prevent dust diffusion through gaps while absorbing vibrations and reducing impact noise (e.g., concrete walls, steel structure connections).

Pipe & Penetration Sealing

Wrapping interfaces where pipes or cables pass through walls/floors to block dust, insects, and reduce noise transmission from pipe vibrations (e.g., air conditioning ducts, ventilation pipes).

Industrial Equipment Sealing

Used for equipment interfaces in industrial plants (e.g., machine tools, production lines), warehouse rolling doors, or loading docks to isolate external dust and noise, protecting equipment and improving working environments.

Elevator Shaft & Stairwell Soundproofing

Installed on elevator door frames or stair handrail connections to reduce vibration noise from elevator operation and airborne sound in stairwells, enhancing the quietness of living or office spaces.

Soundproof Walls & Enclosures

Serving as core components in soundproof structures (e.g., highway noise barriers, equipment enclosures), their elastic compression seals gaps to enhance sound insulation and prevent dust accumulation.

Material Properties

Common materials include EPDM rubber, neoprene, and silicone, known for aging resistance, low-temperature tolerance, and high elasticity, suitable for diverse environments (e.g., wet, high-temperature, or high-dust scenarios).
