The T-type sealing strip-also referred to as a profiled silicone strip or a silicone extrusion strip for mechanical and electrical equipment-is a sealing material custom-engineered to suit specific equipment structures. Its primary function is to fill gaps, prevent fluid leakage, or provide dust isolation. Its core mechanism relies on the elastic deformation of flexible silicone to fill irregular voids, thereby establishing a reliable sealing barrier. These products are commonly utilized in applications involving electrical appliances, equipment cabinets, and machinery where dust and water resistance are required; they may also serve as decorative trim or protective cushioning.
Given the significant variations in equipment interface dimensions, T-type sealing strips are typically manufactured on a custom-order basis. Users must provide specific parameters-such as the cross-sectional profile of the interface, the required length, and the intended compression allowance-enabling the manufacturer to achieve a precise fit through specialized mold development. For sealing electrical cabinet doors, it is essential to account for the compression ratio upon closure (typically 20% to 30%) to ensure the seal remains secure and does not loosen over prolonged use; conversely, seals for mechanical transmission components must balance abrasion resistance with elasticity to effectively prevent oil leakage. Regarding color options, in addition to standard black and white, the strips can be custom-matched to align with the specific color scheme requirements of the equipment.
