How to slow down the aging of Rubber Rail Pads?
To slow the aging of rubber rail pads, store them away from heat, UV light, and moisture, and protect them from physical damage and chemical exposure. During installation and use, regular maintenance, including ensuring proper fastening and replacing worn-out pads promptly, is also crucial for extending their life.
| Rubber Rail Pad | ||
| Technical Parameter | Unit | Value |
| Stiffness | KN | 90-130 |
| Hardness Shore A | ℃ | 72-80 degree |
| Electronic Resistance | Ω | ≥ 106 |
| Tensile Strength before Aging | Mpa | ≥12.5 |
| Elongation before Aging | % | ≥250 |
Storage and handling Control temperature:
- Store rubber products below 38℃ and away from heat sources like electrical motors.
- Limit light exposure: Keep them out of direct sunlight and intense artificial light, which produce UV rays that degrade rubber.
- Protect from moisture: Store in a cool, dry place, ideally with humidity below 75%, or in sealed, moisture-proof bags.
- Prevent physical stress: Avoid hanging, folding, or rolling the pads, as this can cause tension and bending.
- Avoid chemicals: Do not expose the pads to any liquids or vapors that can cause degradation.
Installation and use
- Ensure secure fastening: Regularly inspect that the pads are securely fastened to prevent them from becoming loose and damaged.
- Protect from harsh conditions: Shield the pads from harsh environmental factors to enhance their durability.
- Replace worn pads: Replace any worn-out pads promptly to prevent more significant issues from developing and to maintain the overall integrity of the track.
Rail pad functions
A rail rubber pad is essential in reducing shock and vibration in a rail system. The pad laid under the rail to ensure:
- Load distribution over a larger surface
- Elimination of load concentration and the resultant fatigue stresses
- Centering of loads on the supporting element
- Absorption of uneven contact surfaces between rail and support
- Reduction of noise and vibration
- Sealing between the bottom of the rail and the top of the support
- Reduction of wear of the rail and its support
As a professional rail fastener manufacturer, GNEE RAIL can produce various types of rubber rail pads with different materials, such as natural rubber, EVA, HDPE and so on. Our EVA/HDPE/rubber rail pads are with high elasticity, applying to types for rails such as rail UIC54, UIC60, BS80lbs,BS100lbs, and sizes as ordered. The pads can be customized with or without grooves, in various possible designs, depending on customers' requirements.
