Packing and storage

flake/powder: 20kg/bag、25kg/bag, Packed in woven bag, or in Kraft paper bag with plastic liner inside.

bakelite powder and phenolic resin powder different.

What is the difference between phenolic resin powder and bakelite powder? bakelite’s chemical name is phenolic plastic, which is the first variety of plastics to be put into industrial production. Phenolic resin can be prepared by polycondensation of phenols and aldehydes in the presence of acidic or alkaline catalysts. Bakelite powder is obtained by fully mixing phenolic resin with sawn wood powder, talc powder (filler), urotropine (curing agent), stearic acid (lubricant), pigment, etc., and heating and mixing in a mixer. Bakelite powder was heated and pressed in the mold to obtain thermosetting phenolic plastic products.

Bakelite has high mechanical strength,good insulation,heat resistance and corrosion resistance.therefore,it is often used to manufacture electrical materials, such as switches, lamp caps, headphones,telephone casings,instrument casings,etc.“Bakelite”is named after it.
