Testimonials

  • My company has been a customer of Rainbow's for over 10 years. We're constantly calling in rush jobs and Rainbow is constantly rising to the challenge.

    Alison McBrian
  • We've tried other rubber compound mixing companies and they're just not as committed to quality as Rainbow is. I don't have to double-check incoming product when it comes from Rainbow; I know it's right every time.
