Natural Rubber

Natural rubber (NR) is found in the juices of many plants, but the principal source is Hevea Brasiliensis, a tropical tree. Natural rubber is the product that all synthetic rubber materials have tried to duplicate. At REDCO, we have the knowledge and experience to manufacture the custom natural rubber products you need to complete your job. From precision rubber-covered rollers to custom die-cut gaskets and beyond, we’ll deliver high-quality USA-made components made from natural rubber compounds on time and within budget.

Properties of Natural Rubber Material

Natural rubber and natural rubber compounds are composed of polymer polyisoprene. Other materials such as proteins, fatty acids, and more, are often present within natural rubber material. Natural rubber must be vulcanized to be used in industrial applications.

Features of Natural Rubber Compounds

Once processed and vulcanized, natural rubber materials have an impressive stretch ratio, feature a high level of resilience to various factors, and are extremely waterproof. Characteristics of natural rubber compounds include:

  • Specific Gravity: .93
  • Tensile Strength, PSI—Reinforced: 4000
  • Practical Shore A Hardness Range: 30-95

Benefits & Advantages of Natural Rubber Products

Products made from natural rubber are generally resistant to most moderate chemicals wet or dry, organic acids, alcohols, keytones, and aldehydes. They also feature:

  • Excellent room temperature, heat, tear, and abrasion resistance
  • Excellent low-temperature flexibility
  • Good to excellent moisture resistance
  • Good to excellent dielectric properties
  • Good oxidation resistance
  • Good diluted acid resistance
  • Fair to good compression set
  • Fair concentrated acid resistance
  • And many others!

The Limitations of Natural Rubber

While natural rubber material is suitable for many applications and functions well in various conditions, it has a few limitations. Natural rubber is typically attacked by ozone, strong acids, fats, oils, greases, and most hydrocarbons. If these substances are present in your planned use, then a different rubber material will be required in your production.

If you are unsure if natural rubber or a different rubber composite is best for your job, call 775-882-3100 today. The REDCO experts will work closely with your team to find the best solution.

Uses of Natural Rubber Compounds in Industrial Applications

Natural rubber is useful in a variety of applications, including in the manufacturing of tires, shock mounts, energy absorbers, seals, isolators, couplings, bearings, springs, and other dynamic applications. Natural rubber material’s durability, versatility, and flexibility make it a good fit for most manufacturing services and custom rubber molding applications, including:
