Butyl rubber sealing tape plays an indispensable role as a sealing material in insulating glass manufacturing. Its technical characteristics and application value can be systematically outlined as follows:
Core Material Properties & Sealing Mechanism
This product utilizes polyisobutylene rubber as its base material, forming a thermoplastic sealing system with permanent plasticity. It maintains flexibility within the temperature range of -20°C to 80°C, preventing surface cracking or hardening. With an ultra-low water vapor transmission rate of 0.5-0.6g/(m²·year), it creates a dual moisture barrier when combined with secondary sealants like polysulfide sealants, ensuring a dry environment within the insulating layer to sustain excellent thermal insulation performance.
Functional Advantages Analysis
Interface Compatibility: Demonstrates superior adhesion to glass, aluminum spacers, and various substrates. Its high shear strength effectively buffers thermal expansion/contraction effects (e.g., summer expansion/winter contraction) of glass, eliminating seal failure risks
Process Adaptability: Cure-free and solvent-free formulation enables immediate application, perfect compatibility with automated production lines, and significant reduction in workspace requirements
Environmental Resistance: Exhibits excellent resistance to UV radiation, ozone, and chemical corrosion, maintaining performance stability under extreme conditions (e.g., freezing temperatures/coastal humidity) with a design life exceeding 25 years, far surpassing industry benchmarks
Industrial Applications
As the core sealing component for insulating glass units, it is widely applied in building curtain walls, energy-efficient windows/doors, and automotive windshields. Its reliability directly determines product airtightness, water tightness, and thermal/acoustic insulation performance, enabling over 30% reduction in building energy consumption while perfectly aligning with green building certification requirements.
Through material science innovation and manufacturing process optimization, butyl rubber sealing tape provides a durable sealing solution for insulating glass systems, serving as a critical foundation for enhancing building energy efficiency performance.
