A flap seal is a rubber or plastic seal that provides protection and closes gaps without the use of adhesives. Commonly referred to as "trim seals" or "edge seals," flap seals are versatile components in various applications.
Flap seals find extensive use in construction machinery, agricultural machinery, special vehicles, and nursing and welfare equipment. In construction, they protect the periphery of fittings and prevent dust and dirt intrusion. In the industrial sector, flap seals serve as cushioning for machine doors and safety measures to protect edges of sheet metal and steel plates, reducing injury risks. Additionally, they are employed in rubber packing for dustproofing in train window frames and switchboard doors, as well as in wiring protection.
Diverse flap seal types exist, each suitable for different product uses and environments. TPE (thermoplastic elastomer), an eco-friendly material, merges resin and rubber properties, offering ease of processing and recyclability. The oil-resistant type is ideal for machining environments due to its superior oil resistance. PVC (polyvinyl chloride) and EPDM (ethylene propylene rubber) are also used, known respectively for their flame/weather resistance and cushioning properties. Furthermore, flap seals with an aluminum core are notable for easy and adhesive-free attachment.
