Appearance: White needle crystal, a special smell. Melting point (℃): 41 Relative density (water = 1): 1.07 Boiling point (℃): 181.9 Relative vapor density (air = 1): 3.24 refractive index of 1.5418 formula: C6H6O Chemical formula: C6H5OH, PhOH molecular weight: 94.11 saturated vapor pressure (kPa ): 0.13 (40.1 ℃) heat of combustion (kJ / mol): 3050.6 critical temperature (℃): 419.2 phenol: mainly phenolic fiber thermoplastic novolac resin as raw material, after melt spinning immersed in an aqueous solution of formaldehyde and hydrochloric acid poly in for curing get fiber body structure of formaldehyde cross-linking. 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 phenol, outstanding fire-resistant properties, limiting oxygen index of 34 phenol preservative, momentary contact of oxygen near 7500 ℃ - acetylene flame, do not melt nor delay burning, self-extinguishing, 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.
