Function Purpose:

NR/SBR Rubber Sheet (General purpose rubber sheet) which can be used in
cutting seals but not recommended for using in high temp.

NR/SBR Rubber Sheet Introduction

NR/SBR rubber sheet is a blended elastomer material that combines the high elasticity of natural rubber (NR) with the improved wear resistance of styrene-butadiene rubber (SBR). This combination provides a balanced performance profile, making it widely used in general industrial applications where flexibility, durability, and cost efficiency are required.

Advantages

NR/SBR rubber sheet offers good elasticity and flexibility, maintaining stable performance even in low-temperature environments. The addition of SBR improves wear resistance, helping the material perform reliably under long-term mechanical contact conditions.

In addition, it provides a cost-effective solution compared with many specialty rubber materials, making it suitable for large-scale industrial usage where economic efficiency is important.

Suitable Applications

NR/SBR rubber sheet is commonly used in general industrial environments, including:

• Sealing gaskets for water pipes and valves

• Low-pressure hydraulic systems

• Mechanical protection pads to reduce friction and impact

• Non-oil medium equipment such as water pumps and air compressors

These applications typically require moderate sealing performance and stable physical properties under standard operating conditions.

Unsuitable Environments

NR/SBR rubber sheet is not recommended for demanding or extreme operating conditions, including:

• High-temperature environments above 80°C, where the material may lose elasticity and become brittle

• Contact with oils (such as engine oil) or organic solvents (such as gasoline), which can cause swelling and material degradation

• High-pressure systems above 10MPa, where sealing performance may not be sufficient

Conclusion

NR/SBR rubber sheet is a practical and cost-effective material designed for general industrial sealing and protective applications. While it does not offer resistance to extreme temperature, oil, or high-pressure environments, it performs reliably in standard working conditions where flexibility, wear resistance, and economic efficiency are the primary requirements.
