ST-3263
Product Overview
ST-3263 is a sealing material composed of synthetic rubber and selected cork particles. This product features low density and high compressibility while maintaining excellent rebound performance and oil resistance, providing a reliable solution for industrial applications requiring effective sealing and shock absorption.
Product Features
High Compressibility: 35-50% compression ratio range effectively conforms to flange surfaces
Excellent Resilience: ≥80% rebound rate ensures long-term sealing stability
Reliable Oil Resistance: Demonstrates strong tolerance to various oil-based media
Superior Flexibility: Passes multiple flexibility tests without cracking
Lightweight Construction: Density range of 550-750 kg/m³ combines light weight with functionality
Typical Applications
Automotive engine and transmission sealing
General industrial equipment gaskets
Home appliance sealing and vibration damping
Mechanical equipment cushioning layers
Technical Parameters (Summary)
Density: 550–750 kg/m³
Hardness: 50–70 Shore A
Compression set: 35–50% (at 400 PSI)
Rebound rate: ≥80%
Tensile strength: ≥0.8 MPa
Cork particle size: 1/2 mm
