SANMODUR is superior to competitive modelboards because of it’s manufacturing process. Sanyo’s patented “Mechanical Frothing” process results in smaller cells (bubbles) and a smoother surface. As a result of this finer cell structure, a lower density SANMODUR grade will provide surface quality equal to a higher density competitive product. Smaller cells allow engineers and modelmakers to “lighten up” to reap significant material cost savings without sacrificing surface quality. SANMODUR has been used extensively by Asian automakers for more than 30 years.
