Bakelite sheet BASICAL Color: natural orange,yellow,nlack,brown Thickness: 3mm-50mm Size: 1000mm*2000mm ESD Value:10*6-10*10 Charactor 1)excellent electrical insulation made it quite desirable as casing for the growing electrical industry 2)for making pattemed molds,which enabled increased production. 3)the ingredient to make the resin(carbolic acid and formaldehyde)were easily obtainable and available in large amount Applications Bakelite is not extensively used for general consumer products any more,due to the cost and complexity of production and its brittle nature.However,it was used in the past in a myriad applications,such as saxophone mouthpiece,cameras,solid-body electric guitars,rotary-dial telephones,early machine guns,and appliance casings.it was one point considered for the manuufacturer of coins,due to a shortage of traditional manufacturing material An exception to the overall decline is the use in small,precision-shaped components where their specific properties are required,such as molded disc brake cylinders,saucepan handles,electrical and plugs and switches,and electrical iron parts,today,bakelite-type materials are manufactured and produced in the form of sheets,rods and tubes for many industrial applications inthe electronics,power generation,and aerospcae industries,and under a varity of commercial brand names Today, the resin is used mostly for heavy industry products and less for daily necessities.For example,the material is used often for leiterplatten,piece of machinery which are under great thermal and mechanical pression such as brake pads,In addition,to this day,phenolic resin is also as a binder for sheet in wood and foam materials.
