Phenol: Phenol novolak fibers mainly of thermoplastic resin as raw material, after melt spinning was immersed in an aqueous solution of paraformaldehyde and hydrochloric acid as a curing treatment, to obtain the body structure formaldehyde crosslinked fibers. To improve the fiber strength and modulus, with 5% to 10% of polyamide melt-blended spun. Such fibers are golden or yellow-brown fiber strength of 11.5 ~ 15.9cN / dtex, fire resistant outstanding performance, limiting oxygen index of 34, the moment of contact with oxygen nearly 7500 ℃ - acetylene flame retardant does not melt, self put out the sex, but also resistant to concentrated hydrochloric acid and hydrofluoric acid, but poor resistance to sulfuric acid, nitric acid and alkali performance. Mainly used for protective clothing and fire or upholstery fabric, also used as insulation, heat insulation and thermal insulation, filtration materials can be processed into a low-intensity, low-modulus carbon fiber, activated carbon fiber and ion exchange fiber. Phenol: insulation materials are mainly phenolic foam material preservative phenolic resins, phenolic foam products is characterized by thermal insulation, fire, light, as insulation, energy, new materials, fire can be widely used central air conditioning system, lightweight insulation color plates, house insulation can drop insulation, thermal insulation materials in the field of chemical pipelines (especially cryogenic insulation), travel and other places. Phenolic foam because of its low thermal conductivity, good insulation properties, known as the king of the insulation. Phenolic foam is not only low thermal conductivity, good insulation properties, also has flame retardant, thermal stability, high light, low smoke, low toxicity, thermal, mechanical strength, noise, and strong resistance to chemical corrosion, weather and many other type of good term advantage, phenolic foam phenol rich source of raw materials prices, low prices, and the production process is simple, extensive product applications.
