Bakelite has characteristics, of insulation, does not produce static electricity, wear-resistant and high temperature and other characteristics, insulated switchgear and variable resistor electronic products, machinery, molds and production line fixture, and can be used in the transformer oiland other products used. Bakelite is a man-made synthetic chemicals, can no longer be portrayed as the other things, it solidified Once thermoforming, have a non-absorbent, non-conductive, high temperature, high strength characteristics, coupled with GF application for electrical products, hence the name. Electronic production tool fixture fabrication, performance test. with excellent electrical, mechanical and processing properties. Paper bakelite is the most common laminate, is the world's most widely used, the use of the largest industrial laminates.
Features:
(1)good electrical performance
(2)mechanical processing performance

Application:
(1)tangerine and black Bakelite is the commonly used insulation material in the producing and processing of jig and fixture,it is also used as the insulation part for textile industry and electric industry.
Comb could also be made from these kinds of Bakelite sheets.
(2)Grinded and punched Bakelite also could be used for the PCB grinding machine, bottom sheet of prototyping machine,testing plate,it has good surface smoothness and the tolerance for thickness is less than ±0.1mm at most.
(3)Cold runner bakelite,fabric based Bakelite is commonly used as the switch ,insulation part or stamping(punching) parts,in the normal temperature,the punching performance is very stable.
