CR 60 B 3 F1 [C5985]

1 of 2 products in this brand

CR 60 B 3 F1 [C5985] general-purpose rubber has an excellent balance of physical and chemical properties that make it suitable in a range of applications. Whilst it may only have a moderate resistance to petroleum-based oil and fuels, CR has a much better chemical, oil, ozone and heat resistance than natural rubber, despite the lower level of physical properties. One major benefit of Neoprene® rubber is that by nature, CR rubber is one of the few self-extinguishing rubbers, which means it is flame resistance. Additionally, its gas permeability is relatively low. For industrial applications, Neoprene® gives excellent rubber-metal bonding and has good levels of rebound resilience. This compound lends itself to being fabricated into many different products with fabric reinforcement.


  • Outstanding physical toughness
  • Wider short- and long-term operating temperature range than general-purpose hydrocarbon elastomers
  • Resistance to hydrocarbon oils and heat (ASTM D2000/SAE J200 categories BC/BE)
  • Resistance to ozone, sun and weather
  • Better flame retardant/self-extinguishing characteristics than exclusively hydrocarbon-based elastomers
  • As with all elastomers, properties inherent in the base polymer can be enhanced or degraded by compounding with additional ingredients

Features & Benefits

Product Background
  • Advantages Of CR Rubber

    • CR Rubber was one of the world’s first oil-resistant synthetic rubbers. This general-purpose rubber has an excellent balance of physical and chemical properties that make it suitable in a range of applications.
  • Disadvantages Of CR Rubber

    • As you may expect from its widespread use for underwater wear, including wetsuits and diving costumes, Neoprene® is water-resistant. However, whilst this is suitable for underwater clothing, Neoprene® also exhibits poor electrical properties.

Applications & Uses

Typical Applications

It is widely used in various applications due to its useful properties and reasonable price point. This is why Neoprene suits belting, coated fabrics, cable jackets, seals and gaiters.
