BMC(DMC)- bulk molding compound: BMC (DMC) is short for bulk (dough-like) molding compound, so there are two names of BMC/DMC at home and abroad, namely bulk molding compound. In China, it is usually called dough-forming compound. Its main raw materials are sheet prepreg made of GF (chopped glass fiber), UP (unsaturated resin), MD (filler) and various additives. DMC materials were first applied in the former West Germany and Britain in the 1960s, and then developed greatly in the United States and Japan in the 1970s and 1980s respectively. BMC block molding compound has excellent electrical properties, mechanical properties, heat resistance and chemical corrosion resistance, which can meet the performance requirements of various products, so it is more and more loved by users. DMC Company is the only company in the world that owns more than 400 kinds of cross-stitch cotton yarn color number patents. At present, the common lines in the domestic market are: French DMC line, German anchor line (ANC line), Thai Fairy line, Thai Venus line, domestic CC line and domestic Rose line. French DMC thread is the most commonly used thread for embroiderers, because many embroideries are marked with DMC thread number. DMC thread has good quality, soft thread and good gloss. The quality of German ANC thread is equivalent to that of DMC thread. In contrast, its color is gorgeous. It is impossible to embroider the embroidery produced by the anchor's own company with it. But you must be careful when buying ANC lines, because a large number of counterfeit lines have appeared recently. The quality of fairy line and Venus line is not so good. Fairy thread often appears in Mona Lisa bags, and the embroidered works are generally the same. Many shops call it Venus thread DMC thread, which deceives many novices. CC line is a replica of DMC line, and now it has come out to the second generation. Although the quality is not as good as DMC line, it is still copied well. The line numbers are the same. The price is also cheap.
