NM Black spacer developed by NanoMicro technology has a pure black background, excellent heat resistance, cold resistance and chemical resistance, and the particle size is very uniform. NM Black spacer can meet the special needs of customers. At present, mainstream sizes of 3.0 µm, 3.5 µm, 4.0 µm, 6.0 µm are mass-produced, and other customized size of black balls' lead time is about two months.
