The Impact of Material Properties on Industrial Rubber Hose Performance


The industrial rubber hose is a highly versatile and critical component of many applications in various industries. It is a flexible conduit designed to transport fluids, such as water, air, and chemicals, from one point to another. The ability of rubber hoses to withstand high pressure, temperature, abrasions, and chemicals is determined by the material properties of the rubber compounds used. In this article, we will explore the impact of material properties on the performance of industrial rubber hoses.

Material Properties of Rubber Compounds

The properties of rubber compounds used in industrial rubber hose manufacturing determine their performance characteristics. The two primary properties of rubber compounds are hardness and elasticity, which are measured on the shore hardness A scale and the elongation at break scale, respectively. Other critical properties include tensile strength, tear resistance, compression set, and abrasion resistance.

The hardness of rubber is one of the most critical properties that impact its performance. The harder the rubber, the more resistant it is to abrasion and shear forces. However, it also makes it less flexible and more prone to cracking in extreme temperatures. The elasticity of rubber determines its ability to stretch and return to its original shape without deforming or breaking.

Tensile strength is another significant factor that affects rubber hose performance. It is a measure of the rubber's ability to resist deformation when subjected to external forces. Higher tensile strength rubber compounds are more durable and can withstand more significant stress without rupturing.

Impact of Material Properties on Rubber Hose Performance

The material properties of rubber compounds used in industrial hose manufacturing have a direct impact on their performance. Below are five ways in which material properties affect rubber hose performance.

1. Abrasion Resistance

Rubber hoses are susceptible to abrasion when used in industries such as mining, oil, and gas, where they come into contact with rough surfaces and sharp edges. The abrasion resistance of rubber compounds used in hose manufacturing is critical in determining the hose's lifespan and efficiency. High-performance rubber compounds with excellent abrasion resistance, such as chloroprene and neoprene, can withstand harsh environments and last longer.

2. Chemical Resistance

Chemical resistance is another critical property of rubber compounds that affect hose performance. Depending on the application, hoses may need to transport chemicals, such as acids and solvents, that can cause deterioration of the rubber. The chemical resistance of rubber compounds varies, and selecting the correct compound for the specific application is crucial for long-term hose durability.

3. Temperature Resistance

Rubber hoses are often exposed to extreme temperatures, both hot and cold, in industrial applications. The temperature resistance of rubber compounds affects the hose's ability to maintain its physical properties, such as elasticity and hardness, under varying temperature conditions. High-temperature compounds, such as silicone, can withstand temperatures up to 450°F, while low-temperature compounds, such as fluorocarbon, can handle temperatures as low as -20°F.

4. Pressure Rating

The pressure rating of a rubber hose is determined by its design, reinforcement, and the tensile strength of the rubber compound. Higher tensile strength rubber compounds can withstand more significant internal pressure, resulting in hoses that are suitable for high-pressure applications.

5. Flexibility

Flexibility is another critical property of rubber hoses that affects their performance. Flexible hoses can bend and flex without losing their shape or integrity, making them ideal for use in tight spaces. Rubber compounds with high elasticity, such as natural rubber and EPDM, make hoses more flexible and durable.


The performance of industrial rubber hoses is highly dependent on the material properties of the rubber compounds used in their manufacture. Selecting the correct rubber compound for the specific application is critical in determining hose performance, durability, and efficiency. By understanding the impact of material properties on rubber hose performance, industries can make informed decisions when selecting hoses that meet their specific application needs.
