Why Is CR Rubber Tube More Expensive Than NBR? | Tuberry®

Why Is CR (Chloroprene Rubber / Neoprene) Tube More Expensive Than NBR Tube ?

When choosing rubber Tubes for industrial machinery or fluid systems, one of the most common questions from customers is:

“Why is CR rubber Tubes more expensive than NBR rubber Tubes?”
Both CR and NBR rubber Tubes are widely used in industrial applications and come with their own distinct advantages. Selecting the right one, however, should depend more on the application requirements than the material’s name or price alone.


 5 Reasons Why CR rubber Tubes Costs More Than NBR

Higher Raw Material and Production Costs
CR (Chloroprene Rubber) is made from chloroprene, a base material that is significantly more expensive and involves a more complex production process compared to NBR (Nitrile Rubber), which is synthesized from butadiene and acrylonitrile. The tight control required during CR formulation and mixing contributes to its higher production cost per unit.

2. Superior UV and Ozone Resistance
CR rubber is naturally resistant to sunlight, ozone, and harsh outdoor conditions without requiring any surface treatment. This makes it ideal for outdoor use. In contrast, NBR degrades more quickly when exposed to direct sunlight or ozone unless additional protection is applied.

3. Flame Retardant Properties
CR rubber offers built-in flame resistance, making it suitable for safety-critical environments like electrical systems, control panels, and areas prone to fire hazards. NBR, on the other hand, requires additional flame-retardant additives to meet similar safety standards.

4. Longer Service Life and Broader Chemical Resistance
CR rubber performs well in both hot and cold environments and resists a wide range of chemicals including acids, alkalis, and solvents. It also offers moderate oil resistance, comparable to NBR with around 18% acrylonitrile content. While NBR excels in oil resistance, CR’s broader resistance range makes it more cost-effective for demanding applications in the long run.

5. Specialty Production and Limited Supply
CR rubber is typically used for specialized industrial applications, such as outdoor engineering, high-durability systems, or safety-critical environments. These applications result in lower production volumes and higher per-unit costs due to supply-demand dynamics.

   

So, Which One Should You Choose?

Both CR (Neoprene) and NBR rubber Tubes have unique advantages. Choosing the right material depends on several key factors:

 The type of fluid being conveyed
 The operating temperature range
 Environmental exposure (indoor/outdoor)
 Safety requirements specific to your industry
