Silicone sealing strips come in various cross-sectional shapes to accommodate different sealing requirements, primarily categorized into two main types:
Solid Silicone Strip
Description: Features a solid cross-section in circular, square, D-shaped, or other configurations. Characteristics: Provides stable compression and support for reliable sealing.
Applications: Commonly used for static sealing in enclosures, appliance housings, and equipment mounting seals.
Hollow Silicone Strip (Bubble Tube)
Description: Features one or more hollow chambers (bubble tubes) within the cross-section.
Features: Exceptional elasticity achieves excellent sealing with minimal compression force, offering superior sound and thermal insulation. Applications: Primarily used for sealing doors, windows, and lids, such as refrigerator doors, oven doors, cabinet doors, etc.
