CAS 9003-35-4 Manufacturer Price Phenolic Formaldehyde Resin Powder Phenolic Resin

Product Description

Product Description

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.

Application of Phenolic resin :

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. The molding powder can be made into various plastic products by molding, transfer molding and injection molding. 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. Thermosetting phenolic resin molding powder is mainly used in the manufacture of high electrical insulating parts.
• Rosin modified phenolic resin, butanol etherified phenolic resin, p-tert-butyl phenolic resin and p-phenyl phenolic resin have good miscible with tung oil and linseed oil, and are important raw materials in coating industry. The first two are used to prepare low and intermediate paints, and the latter two are used to prepare high-grade paints.
• 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: The formaldehyde-crosslinked structural fibers were obtained from thermoplastic linear phenolic resin by melt spinning and curing in aqueous solution of polyformaldehyde and hydrochloric acid. 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, mo-rtar; Phenolic resin impregnated, pressed graphite products.
• Thermal insulation material: 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.
