Solid phenolic resin is yellow, transparent, amorphous lumpy substance, slightly reddish due to free phenol, the specific gravity of the entity is about 1.7 on average, easily soluble in alcohol, insoluble in water, stable to water, weak acid, weak alkali solution. Resin made by phenol and formaldehyde under the condition of catalyst polycondensation, neutralisation and water washing. Due to the choice of catalyst, can be divided into two categories of thermosetting and thermoplastic. Phenolic resin has good acid resistance, mechanical properties, heat resistance, widely used in anti-corrosion engineering, adhesives, flame retardant materials, abrasive disc manufacturing and other industries.

NEWS
Furan resins are thermosetting resins that cross-link with each other when heated and cure without the addition of a hardener. Acids play a catalytic role in the curing reaction and also reduce the temperature required for heat curing.
One of the main uses of phenolic resins is the production of compression moulding powder for moulded products. Using roller pressing method, screw extrusion method and emulsion method to make the resin impregnated with fillers and other additives mixed evenly, and then crushed and sifted can be made to pressure moulding powder.

New phenolic resin can be used as a bonding agent for diamond grinding wheels
New phenolic resin can be used as a bonding agent for diamond grinding wheels, the use of new phenolic resin and phenolic resin mixed with 1:3, not only improves the strength of phenolic resin, but also improves the heat resistance and grinding ratio. If the new phenolic resin is used alone,
New phenolic resins are polymer compounds
New Phenolic Resin is a polymer compound, which is produced by the condensation reaction between phenol and aryl ether. New phenolic resin has good mechanical properties, heat resistance, widely used in diamond products
Furan Resin Properties and Applications
Properties and applications of furan resins--Uncured furan resins have good mixing properties with many thermoplastic and thermosetting resins, so they can be modified by mixing with epoxy resins or phenolic resins.
