Product Description
PMC™-790
PMC™-790 is a Shore 90A industrial urethane rubber compound designed to meet the most stringent requirements of industrial production applications. It is a very hard rubber that offers superior tear and tensile strength as well as impact and abrasion resistance.
FOAM-iT!™ 10 SLOW
Smooth-On’s FOAM-iT!™ Series are two-component water blown rigid foams that are versatile and easy to use. FOAM-iT!™ products are available in 3lb., 4 lb., 5 lb., 8 lb., 10 lb.,15 lb. or 26 lb. per cubic foot densities. Parts A and B are measured and mixed in equal amounts by volume. The mixture is then poured into a mold or other form (apply release agent if necessary). The mixture will expand many times original volume (depending on which FOAM-iT!™ product you are using) and develop a uniform cell structure. FOAM-iT!™ 10 SLOW is a 10 lb. density foam with a long, 3.5 minute working time, taking 1 hour to reach handling strength and 4 hours to cure. FOAM-iT!™ 10 SLOW is designed for large-pour industrial, art-related and special effects applications.
FOAM-iT!™ products can be used as a straight casting material, backfill material for hollow castings (adds structural strength) or as an encapsulation material, etc. They can be color pigmented with SO-Strong™, UVO™ or IGNITE™ colorants and are used for a variety of art/ craft, industrial design and special effects applications.
