Custom Rubber Compounding

While most customers know Alliance Rubber Company for our reputation for producing the world’s finest rubber bands, we also provide quality rubber material to your specifications. Our years of creating and modifying formulas in-house have resulted in a library of hundreds of formulas to meet many different needs. If one of our formulas doesn’t fit your requirements, we can find one that does. We can also use your own specified formula.

Our rubber compounding division is specially equipped for natural rubber and polyisoprene synthetic rubbers, but can also assist you with thermoplastic elastomers, EPDM and Silicone compounds.

  • EPDM: Good resistance to heat, ozone, and sunlight, and retains flexibility at low temperatures (NO CARBON BLACK)
