Rubber Seal Strip for Automotive Steel Plate

Rubber Seal Strip for Automotive Steel Plate

A rubber seal strip for automotive steel plates is a durable, high-performance sealing component designed to provide vibration damping, corrosion prevention, and noise reduction between metal panels in vehicles. It is commonly used in doors, hoods, trunks, and chassis assemblies to ensure airtight and watertight protection.
Key Features & Benefits
✔ Anti-Corrosion Barrier – Prevents galvanic corrosion between dissimilar metals (e.g., steel-aluminum contact).
✔ Vibration & Noise Control – Absorbs road/engine vibrations, reducing cabin noise (NVH reduction).
✔ Weather & Chemical Resistant – EPDM or Nitrile rubber withstands oils, road salts, and extreme temps (-40°C to 120°C / -40°F to 248°F).
✔ Compression-Resistant – Maintains seal integrity under constant pressure.
✔ Easy Installation – Self-adhesive backing or clip-on design for quick assembly.
Common Applications
Door & Hood Seals – Between steel frames and outer panels.
Chassis & Underbody – Protects joints from water/salt splash.
Battery Trays – Insulates steel brackets in EVs/hybrids.
Fender Liners – Reduces road debris rattling.
Material Options
Material Best For Limitations
EPDM Weather resistance (UV/ozone) Weak against oils
Nitrile (NBR) Oil/fuel exposure Less flexible in cold temps
Silicone High-temp areas (exhaust shields) Higher cost
Installation & Maintenance
Surface Prep – Clean steel with alcohol to ensure adhesion.
Alignment – Press firmly along the entire contact surface.
Inspection – Check for peeling or hardening during servicing.
