Automotive Sealing Foam Tape
OPALUS PACK manufactures automotive sealing foam tape as an automotive-grade sealing and NVH damping material designed for gap filling, anti-rattle control, and weather sealing applications. As a manufacturer and supplier, OPALUS PACK engineers foam structures that maintain compression stability and long-term sealing performance in door systems, dashboards, HVAC ducts, and interior assemblies. The material reduces vibration transmission, blocks dust and moisture ingress, and compensates for assembly tolerances in dynamic vehicle environments.

Key Features of Auto Double-Sided Tape
Product Overview
Automotive sealing foam tape is developed as an automotive foam sealing material used to solve structural sealing and vibration control challenges in vehicle assemblies. OPALUS PACK designs this material as a compressible interface for automotive gap filling foam material applications where irregular tolerances between plastic, metal, and composite parts must be stabilized.
In vehicle structures, micro gaps formed by manufacturing variation and thermal expansion can lead to air leakage, vibration transfer, and noise generation. This is where the NVH sealing foam tape solution becomes critical. The foam structure maintains controlled compression force, ensuring continuous sealing pressure without rigid bonding between components.
Benefits
– Helps reduce vibration noise generated from repeated micro-movements in vehicle interiors
– Works effectively in 0.5 mm to 6 mm gap conditions commonly found in automotive assemblies
– Maintains stable performance under automotive temperature range of -40C to 90C
– Keeps sealing function stable with compression set typically within 25% under standard test conditions
– Reduces squeak and rattle caused by plastic-to-plastic and plastic-to-metal contact points
– Supports long-term NVH stability in vibration-prone interior structures
– Helps reduce indirect airflow noise caused by small structural gaps
– Improves overall cabin comfort by stabilizing interface movement over time
Why Is Compression and Recovery Important in Real Automotive Use?
When installed, foam tape is compressed to match the available gap between components, typically in the 0.5 mm to 6 mm range. This compression creates the sealing force that keeps parts stabilized during operation.

FAQ
Q1: What is automotive sealing foam tape mainly used for?
It is used to fill irregular gaps in vehicle assemblies and provide sealing, vibration damping, and NVH noise reduction between structural and interior components.
Q2: Can it reduce squeak and rattling noise in vehicles?
Yes, it helps reduce squeak and rattle by absorbing micro-movements between plastic and metal parts, preventing direct rigid contact inside doors, dashboards, and HVAC systems.
Q3: What gap range can automotive sealing foam tape handle?
It typically compensates for gaps between 0.5 mm and 6 mm, depending on foam density and compression design.
Q4: How does temperature affect its performance?
High-quality foam tape maintains stable performance under automotive conditions from -40C to 90C, with controlled compression recovery to ensure long-term sealing stability.
