Natural 70 HG is a premium grade wear resistant 70 Duro natural rubber sheet with heavy nylon reinforcement.
FEATURES
Natural 70 HG Reinforced Rubber is a premium, heavy-duty natural rubber compound designed for high-load bearing and isolation applications where rigidity, dimensional stability, and long-term strength are essential. With a hardness of 70 Duro, it provides a firm, durable bearing surface capable of supporting large compressive loads while maintaining shape and performance under sustained pressure.
The material is reinforced with a high-strength nylon fabric layer that significantly improves tear resistance and dimensional stability. This reinforcement ensures the sheet retains its form and integrity even under heavy static or dynamic loads. It makes the compound ideal for use in rigid bearing pads, load transfer interfaces, and base isolators where minimal compression is required.
Natural 70 HG Rubber exhibits excellent fatigue and wear resistance, giving it a long service life in demanding structural environments. Its natural elasticity allows it to absorb minor vibration and impact while maintaining consistent load distribution between steel and concrete interfaces.
The compound also demonstrates good weathering, ozone, and UV resistance, making it suitable for external and exposed installations. It performs reliably in both indoor and outdoor environments, retaining its mechanical properties despite sunlight, temperature variation, and moisture exposure.
APPLICATIONS
Natural 70 HG Reinforced Rubber is used in construction, civil infrastructure, and precast engineering applications where a stiff, dimensionally stable, and non-compressible rubber bearing material is required.
It performs exceptionally well in applications subject to high static loads or where maintaining alignment and level under heavy bearing pressure is critical.
Its reinforcement and high hardness make it ideal for rigid bearing and isolation systems, providing reliable load transfer between concrete, steel, and precast elements while limiting movement and deflection. It helps protect structures from fatigue, vibration, and stress concentration while maintaining tight tolerances.
Natural 70 HG Rubber is commonly used in:
- Rigid structural bearing pads and bridge bearings carrying heavy compressive loads
- Load transfer plates and interface pads between concrete and steel elements
- Precast construction supports and machinery bases requiring dimensional stability
- Isolation and vibration-control applications where reduced deflection is essential
- Exposed outdoor bearings and expansion joints in civil works
With its combination of strength, rigidity, and reinforcement, Natural 70 HG Rubber provides a dependable long-term solution for engineers seeking a high-duro, fabric-reinforced bearing material for critical structural applications.
