    Legendary Quality

    Introducing a selective product line should show you how focused and serious we are surrounding the operations of this business. We have worked hard over the past two years building long-term mutually beneficial relationships to ensure the finished products, material availability and customer service far exceed what industry standards demand. It is our commitment to our partners and customers which will give Rubatex® the strength to prosper for many years to come.

  • Rubatex® Founding

    Rubatex® - The First 75

    Rubatex International, LLC was originally founded in 1935 with a mission to set the standard in quality for which all closed cell rubber products were to be judged. They were determined that no possible fineness in craftsmanship or input material be overlooked in the achievement of that purpose. As such, generations of respect and recognition have contributed to the brand becoming almost synonymous with the industry.

  • Rubatex® Today

    We are not an investment or a venture capitalist firm. We are a rubber company focused on delivering quality products our customers can rely on.  We understand the future of our business relies heavily on the quality and consistency of our product offering. As such, we have invested in the equipment, tooling, formulations and technical knowledge to rebuild a product line that leverages the significant successes of Rubatex's heritage.

Rubatex® Materials Under Development

R451 Neoprene 

The Rubatex® R 425 N thru R 451 N represent a range of firmness and density in a good to excellent performing 100% Neoprene elastomer content. These serve as excellent performers in mechanical seals, automotive, aerospace, commercial, architectural, transportation, and many other medium to rugged service conditions. Due to the inherent weather and petroleum resistance, they are very good performers and would be considered as somewhat superior to elastomer blends.

R421 Neoprene/EPDM/SBR Blend 

Most all cellular rubber manufacturers offer various grades of blended materials. The elastomeric blends are offered in low density higher compression set and generally provide simple properties for simple applications, as in the R 42 series of Neoprene/EPDM/SBR blends. Such blends are carefully designed to make the best combination of economies and performance. These provide good and adequate performance applications such as low pressure moisture and air seal, anti-vibration, compression seals such as lamp gaskets and other static applications.

NEOPRENE LAMINATE - PRESS MOLDED BUNS

Rubatex®​ Neoprene Laminate is a high quality closed cell rubber product formulated from a mixture of rubbers as the base substance as well as a combination of other components. Offered in a variety of neoprene qualities (LS, S, HS, HHS, NF, W, CR103) allows this product to be suitable for a variety of diverse applications and needs. Its excellent insulation, high dynamic, weather and ozone resistance, tear proof and non-abrasive, anti-aging, high tensile strength and impact resilience, and good adhesive values make it a long lasting durable material. Additionally, it is environmentally friendly, tolerated well by human skin, water impermeable, resistant to fungi and bacteria, and stable against sea water and diverse chemicals allowing it to be a quality performing product. This cellular rubber works best for outdoor, sporting, industrial, technical and protection applications.

Rubatex®​ Neoprene Laminate types differ in cell structure, degree of hardness, extensibility, load-bearing capacity and compression behaviour.
