| 摘要 |
FIELD: polymer materials. SUBSTANCE: invention relates to electric- and construction-destination polymeric phenol-formaldehyde compositions working at temperatures from -60 to 200 C, which can be used for fabrication of pressed materials. Composition contains resol-type phenol-formaldehyde resin, novolac-type phenol-formaldehyde resin, dosed glass fiber, stearic acid, urotropin, burnt magnesia, kaolin, calcium stearate, wood flour, polyvinylbutyral or polyvinyl acetate. EFFECT: improved flowability, heat resistance, and impact elasticity and thereby enabled fabrication and exploiting of quality profiled parts for modern devices made from pressing materials. 2 tbl, 4 ex
