NR 38 Natural Rubber Sheet — Premium High-Performance Rubber Solution for Industrial Use

Introduction

The NR 38 Natural Rubber Sheet is a premium-grade industrial material designed for heavy-duty environments where resilience, elasticity, and abrasion resistance are essential. Manufactured with 95% high-purity natural rubber imported from Thailand, NR 38 undergoes a unique wet rubber refining process that preserves the integrity of its natural molecular structure. This advanced process ensures excellent elasticity, superior wear resistance, and a longer service life than ordinary rubber sheets.

NR 38 is particularly effective in wet abrasion and impact-intensive conditions, making it the preferred choice in industries such as mining, mineral processing, dewatering, and slurry transportation. Its outstanding physical properties help maintain equipment efficiency and reliability even under the toughest working conditions.

Key Features and Advantages

1. High-Purity Natural Rubber Composition

NR 38 is formulated using 95% pure natural rubber with minimal synthetic fillers. This high natural content ensures exceptional elastic recovery, tensile strength, and flexibility. The wet refining process minimizes structural distortion and maintains the rubber’s natural polymer chains, resulting in a sheet that performs consistently across a wide range of temperatures and pressures.

2. Exceptional Physical Performance

• Tensile Strength: 23 MPa

• Elongation: 750 %

• Specific Gravity: 0.98 ± 0.03 g/cm³

• Hardness: 38 Shore A

• Operating Temperature Range: -40 °C to +70 °C

These physical characteristics make NR 38 both strong and flexible, allowing it to absorb shock, resist tearing, and maintain dimensional stability under dynamic stress.

3. Enhanced Wet Abrasion Resistance

NR 38 exhibits superior wear performance in wet grinding and slurry-handling systems. Its self-reinforcing molecular structure prevents cracking and surface degradation caused by water or friction. Compared to conventional rubber materials, NR 38 maintains its elasticity and surface integrity for a much longer time, reducing maintenance and replacement frequency.

4. Durability and Cost Efficiency

Due to its outstanding toughness and stability, NR 38 provides excellent long-term cost savings. It reduces downtime associated with material replacement and offers consistent protection for metal equipment, extending overall service life and lowering operational costs.

Applications

NR 38 Natural Rubber Sheet is widely used in multiple industrial sectors where resistance to impact, wear, and vibration is vital:

• Mining and Mineral Processing: Used as rubber lining for pipes, chutes, tanks, and hoses in areas exposed to severe wet abrasion such as dewatering and desliming systems.

• Industrial Protection: Applied as vibration dampers, sealing gaskets, and wear pads to safeguard metal components from impact and corrosion.

• Material Handling: Serves as an impact-absorbing lining for conveyor systems, transfer points, and hoppers to minimize product damage and noise.

• General Engineering: Suitable for machinery bases, anti-slip flooring, and protective pads in industrial and workshop environments.

By combining durability and flexibility, NR 38 is an excellent choice for industries seeking reliable material performance in both dry and wet operations.

Sizes and Specifications

• Standard Sheet Sizes: 1.0 m × 10 m / 1.2 m × 10 m / 1.5 m × 10 m

• Thickness Range: 1 mm – 25 mm
