A Long History of Serving Our Customers

For more than 50 years, DSI’s DORTITE Sponges have changed and improved the performance in a wide range of applications. In 1978, some of the company’s current owners purchased two divisions from their employer at the time – Diversified Specialties, Inc. (DSI). The primary owner was the lead chemist. Since then, DSI has developed a reputation for:

  • Unbeatable quality with no failures. A trusted resource that gets it right the first time.
  • Small runs.
  • Low minimums.
  • Short lead times and fast delivery.
  • Exceptional customer service.
  • Global distribution from knowledgeable distributors.

DSI’s DORTITE Sponges are custom-formulated and engineered to excel in specific applications – with maximum performance and longer product life. DSI is a dynamic solution-based organization devoted to developing the best possible products for a changing industrial environment.
