Crypton Inc., a West Bloomfield maker of stain-resistant fabrics, has made a name for itself in restaurant circles by covering the booths at McDonald's franchises across the country.

Now, Randy Rubin, who started Crypton with her husband, Craig Rubin, in the basement of their Bloomfield Hills home 15 years ago, wants the company to be known in households.

The firm -- with about 120 employees including 22 at its sales operations in Michigan -- has applied its expertise in stain- and bacteria-resistant treatments to mattress fabrics, pet beds, leather treatments, wall-coverings for cubicles, cleaning products and carpeting.

"We are making enormous strides to getting into the consumer market," Randy Rubin said.

The new products have helped increase sales 10% from 2007 to 2008 for Crypton, loosely named after Krypton, the fictional planet where Superman was born.

As Crypton added new products to its lineup, the company said sales increased more than 50% from 2004 through 2008. The company declined to give specific revenue figures.

Crypton treats fabrics at a plant in Kings Mountain, N.C., west of Charlotte, and outsources the manufacturing of some of its other products.

Crypton's carpeting, which Rubin says offers stain- and bleach-resistant fibers in more colors than what's available on the market, stands to expand the firm's opportunities at hotels, nursing homes and hospitals. But it is Crypton's products for children's furniture, mattresses and pet beds that could help the company make a name for itself in homes.

Two years ago, the firm also started selling its stain-resistant fabrics at Jo-Ann Fabric and Craft Stores.

But the company owes much of its success to McDonald's.

Craig and Randy Rubin married three months after they met in 1993 and also started the business that year. McDonald's was their first customer after the couple met the fast-food chain's head of design at a hospitality trade show.

The Rubins' stood by in McDonald's test kitchen as their products were smeared with condiments, to see if the fabric could be cleaned as easily as vinyl.

"That was the beginning of a lot of good things," Randy Rubin said, recalling that back then they had used their home kitchen as a test lab.

Rubin said sales of the company's core products, including fabric, have declined. But adding products such as mattress fabric, pet beds and wall coverings has helped the company grow.

"Employment is staying steady," Rubin said. "We did downsize in Carolina and in Detroit. But we're slowly trying to rebuild."
