Since the beginning, asbestos has been used as a reinforcement material for brake pads. Asbestos fiber has high strength and high temperature resistance, so it can meet the requirements of brake pads and clutch plates and pads. This kind of fiber has strong tensile capacity, can even match with advanced steel, and can withstand high temperatures of 316°C. What's more important is that asbestos is relatively inexpensive. It is extracted from amphibole ore, which has been found in many countries.

In asbestos-based brake pads, asbestos accounts for 40-60%, but people now find that most asbestos are potentially harmful. Asbestos has been confirmed by the medical community as a carcinogen, and its needle-like fibers easily enter the lungs. Staying, causing irritation, can eventually lead to the occurrence of lung cancer, but the latent period of this condition can be as long as 15 to 30 years, so people often do not recognize the hazard caused by asbestos.
Our isostatic graphite and Molded Graphite were tested at the National Electrical Carbon Products Quality Supervision and Inspection Center. The main physical and chemical performance index as follows: the compressive strength--125 mpa, shore hardness -- 65 degrees, resistivity --12 mu Ω m. At the same time, the 10μm,8μm,6μm,4μm products have already began Large-scale production,.and unanimously acknowledged by customers. The 2μm,1μm graphite products are under trial. Our company high quality of isostatic pressing special graphite yield above 90%, far ahead of industry the yield of 70%, the first in the country.
EDM graphite, also known as graphite block for EDM, is a new type of material, which is now more and more widely used in the precision mold processing industry. At present, in mold processing plants in developed European countries, more than 90% of mold processing electrode materials are graphite. Copper, the once dominant electrode material, has almost lost its advantages compared with graphite electrodes.
