Over the past forty years, Ultralon has established itself as a niche manufacturer of high quality closed-cell cross-linked foams, with a very tight consistent cell structure.

The company also supplies PE and EVA foam to the orthotic, construction and packaging sectors around the world. U-DEK is the company’s marine brand which is focused on the production and supply of foam for marine decking in the USA, APAC and EU regions.
