Phenolic resin, originally colorless or yellowish-brown transparent in granular or powdered form. Resistance to weak acid and weak alkali, decomposition occurs in strong acid, corrosion occurs in strong alkali. Insoluble in water, soluble in acetone, alcohol and other organic solvents. It is obtained by polycondensation of phenol aldehyde or its derivatives
Other Name:formaldehyde,phenol polymer; Paraformaldehyde
Apperance: Solid: Yellow granule, powder or pale yellow flake; Liquid

Phenolic resin is mainly used in the manufacture of various plastics, coatings, adhesives and synthetic fibers.
Compression molding powder
The production of molding powder for molded products is one of the main uses of phenolic resin.
Thermoplastic phenolic resin molding powder is mainly used in the manufacture of switches, sockets, plugs and other electrical parts, daily necessities and other industrial products, And also used in the manufacture of high electrical insulating parts.
Phenolic glue
Thermosetting phenolic resin is also an important raw material for adhesives. The single phenolic resin is brittle and is mainly used for bonding plywood and precision casting sand.
Phenolic fibre
.Mainly used as protective clothing and flame resistant fabrics or interior decoration, can also be used as insulation, heat insulation and heat insulation, filter materials, etc., can also be processed into low strength, low modulus carbon fiber, activated carbon fiber and ion exchange fiber.
Anti-corrosion material
Several forms of thermosetting phenolic resin commonly used in the field of corrosion prevention: phenolic resin coatings;
Phenolic resin FRP, phenolic resin - epoxy resin composite FRP; Phenolic resin mastic, mortar; Phenolic resin impregnated, pressed graphite products.
It is mainly phenolic resin foam material, which can be widely used in central air conditioning system, light insulation color
steel plate, house insulation and energy reduction insulation, chemical pipeline insulation material, vehicle and ship insulation field.
25KG bag or Drum ,
also be packed according to customer's needs.
