TOKAR GMBH

Physical and chemical properties:

usually refers to liquid or solid products obtained by the reaction of phenol or its homologues (such as cresol and xylenol) with formaldehyde. According to the different types of raw materials, the ratio of phenol to aldehyde and the type of catalyst, thermoplastic and thermosetting resins can be prepared. Thermoplastic phenolic resin (novolak resin) only melts when heated, but can't become insoluble. However, when curing agent (such as hexamethylenetetramine) is added, it can be transformed into thermosetting, which is generated by using trifunctional or difunctional phenols as raw materials when the amount of phenol (mole) exceeds the amount of aldehyde (mole) and acidic catalyst. Thermosetting phenolic resin becomes insoluble when heated. Phenolic resin is resistant to acid, alkali and heat.



Product use:

used as tackifying resin for chloroprene adhesive and vulcanizing agent for butyl rubber. Store in a cool and ventilated warehouse, away from fire and heat sources.
