Anhui Xinlei powder technology company is mainly engaged in the development of silicon materials research, production management, technical consulting, materials testing in one of the high-tech enterprise, is committed to non-metallic mineral products, research and development and has advanced powder production technology, production of shielding materials of spherical silica filler nanoparticles. The company has independent intellectual property rights of the patented technology, our products lead at home, use of our products to reduce production costs. Meet customer needs is our responsibility, the customer may make any special requirements technical requirements, we can on behalf of research and development. 
 PTC materials, packaging materials doped spherical silica composite materials reduce the volume resistivity at room temperature, PTC intensity increase, which polymer PTC material to address the high volume resistivity at room temperature and low intensity conflict with the PTC provides a new way PTC materials have also found improvement. In addition, radiation crosslinking can very well increase the material strength and reduce the NTC PTC intensity.
