牌号简介 About |
---|
HMA 016是一种高密度聚乙烯牌号,其特点为可快速回收并具有良好的冲击强度。 它具有高光泽和高外形稳定性。 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 (Note: FOAM-iT!® 8 is measured and mixed 2A:1B by weight). 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!® 3, 4, 5, 10, 15 and 26 have a handling time of about 20 minutes and reach full cure in 2 hours. FOAM-iT!® 4 Black is pre-pigmented to a very deep black color. 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!® 8 is a unique, self-skinning foam with a finer, more uniform cell structure than the other FOAM-iT!® products. FOAM-iT!® 8, 15 or 26 can be cast in blocks as a machinable prototype modeling board. All 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. |
