Locally Made. Globally Admired.

One area that truly sets FSI apart from our competitors is the level of services we provide to our customers. We are proud to have helped many companies start foaming their products for the very first time… to have developed special foam systems to solve tough problems for many others… and to have always been happy to visit our customers to provide routine service and support.

We are committed to “Service What We Sell.”

Routine “On-Site” Services

No company can match our ability to meet the specific needs of the customers we serve. In fact, for more than 40 years, FSI has been distinguished by our technical superiority, as well as by an approach to customer services that’s always been thorough, comprehensive, and yet completely flexible.

We won’t just visit your facility when you have a problem – we’ll be there for routine maintenance to make sure unplanned downtime is kept to a minimum. Plus, our technical support specialists are always available to provide you with the answers, assistance and critical resources you need, day after day, year after year.

Production Demo, Trial & Implementation

At FSI your success is always our goal. So whether you’ve been foaming products for years or you’re just getting started, we make certain that your polyurethane solutions work the way they’re supposed to before you even take your first delivery.

After consulting with you to develop a product that meets your objectives and needs, our engineers and experts conduct extensive trials to assure that performance and quality meet strict FSI standards. We also demonstrate these trials and other how-to’s with every customer, plus develop standards and guidelines for them to help make sure product implementation and use is successful, every time. At FSI we take out the guesswork and deliver results.

Process Consultation

Finding effective solutions to our clients’ challenges is all part of a day’s work here. While we offer many standard urethane solutions, every customer’s needs are different, and we make sure that the solutions we develop for them work exactly how they expect them to work, no matter the application.

FSI also specializes in developing custom solutions for our customers when standard options won’t meet their exact needs. We welcome any problem, any challenge, at any time – and will find the solution to get the job done efficiently and effectively.


Whether we’re producing a custom or toll-blended PU solution for you, or working with products you ship to us, FSI offers a full range of flexible repackaging options for our customers.

We have the experience and know how to guide you through the repackaging process – from the idea stage to container selection to packaging options and labeling, all the way through global logistics and delivery. So you’ll gain all the benefits and advantages of our 40+ years product development, manufacturing, packaging and distribution, and put that knowledge to work for your products on day one.
