Over 50 Years of Innovation

The KYDEX® Thermoplastics story began more than 50 years ago, in 1965, when KYDEX® 100 was invented near Philadelphia at the Rohm & Haas Co. At its outset, this high-impact, fire-rated and acrylic-modified PVC thermoplastic sheet proved ideal for hard-to-form parts for a wide range of applications, including aircraft components and mass transit interiors. It quickly gained a reputation as an extremely durable, chemical resistant, and fire-retardant polymer innovation. 

In 1987, KYDEX® Thermoplastic production assets and the brand name were purchased by a small team of ex-Rohm & Haas employees, who started the Kleerdex Company in Bloomsburg, Pennsylvania. In 1990, the company was acquired by SEKISUI Chemical. 

The team that purchased KYDEX® Thermoplastics recognized the profound potential in the product. Their entrepreneurial spirit and unfailing resolve to expand the product line and deliver more than our customers could imagine drove its early success and continues to influence today’s product lines.

Roots in transportation 

After the production assets were installed in Bloomsburg, the team worked diligently to quickly expand the portfolio beyond the workhorse KYDEX® 100, which was already widely used by domestic airlines for aviation interior components. In 1990, the team invented KYDEX® 6200 for mass transit interior components to meet newly established low-smoke regulations set forth by the Federal Transit Administration. 

Soon after, the aviation portfolio grew with KYDEX® 657 and KYDEX® 6565 to meet and exceed the Federal Aviation Administration’s (FAA) more stringent regulations for heat release and smoke density. 

Innovation through process 

Excellence in manufacturing, customer service, and design are just a few foundations that have made KYDEX® Thermoplastics a success. Through its early adoption of Kaizen methodology and continuous improvement, the company has always provided best-in-industry lead times and low minimum order quantities. In 1993, KYDEX, LLC was one of the first plastic manufacturers in North America to achieve ISO 9001 certification. 

Innovation through design 

Since its early days, KYDEX® Thermoplastics were known for having refined, integral color. The original nine-color palette quickly grew to 33 standard colors, and now includes over 4,000 library colors with virtually unlimited color matching capabilities. Over the decades, design capabilities have grown with the addition of decorative lamination and light-reflective pigments. With the recent addition of pattern-in-product with Infused Imaging™, design options are more far reaching than ever before. 

The sky's the limit with collaboration 

Collaboration with our partners and inspiration from other industries have engendered development of new technologies, products, and applications. Today, KYDEX® Thermoplastics are virtually everywhere, from the planes in our skies to devices in your doctor’s office. 

At the SEKISUI KYDEX designLab™, customers work with design and R&D teams on color and finish to begin, refine, or extend a design. Making the world safer is the focus of our FSTLab™, where we collaborate with suppliers, engineers, and end users on developing fire resistant materials. 

The first 30 years of KYDEX® Thermoplastics have been an inspiring journey. We’ve been most fortunate in our relationships and resources and are grateful to our customers, employees, and ownership. The future certainly looks bright for building on that legacy together for decades to come. 

SEKISUI KYDEX will be closed November 25-26, 2021 in observance of the Thanksgiving Holiday in the U.S.
