The phenolic cotton cloth laminated sheet is laminated material made through the hot pressing of two or more layers of cotton cloth, impregnated or reinforced with synthetic thermo-reactive resins of phenol and cresol formaldehyde type. Under normal state, this insulating material comes with excellent electrical and mechanical properties. It has been extensively used as electrical insulation parts for machines, motors and electrical equipment. Also, the laminated sheet can be applied in transformer oils.

Applications
Of excellent insulation, wear resistance, shock absorption and explosion proof performance, the phenolic cotton cloth laminated sheet is used to make parts for electromechanical equipment in high demand for these properties including gear wheels, axle sleeves, guide wheels, washers, etc. High quality phenolic cotton cloth sheets are commonly used for making structural parts of precision instruments.

Application Guide
PFCC201: For mechanical use, with superior mechanical property but inferior electrical property as compared with the PFCC202 phenolic cotton cloth laminated sheet;
PFCC202: For both mechanical and electrical use, with excellent electrical property;
PFCC203: For mechanical use, recommended to make small size parts for precision instruments, with better mechanical but poorer electrical performance than the PFCC204 laminated sheet;
PFCC204: For both mechanical and electrical use, outstanding in mechanical and electrical performance, recommended to make small parts;

C850.1: For mechanical use (from coarse cloth), excellent in mechanical performance and slightly poor in electrical performance, like the C series sheet in NEMA standard;
C850.2: For both mechanical and electrical use (from coarse cloth), with great electrical performance, like the CE series sheet in NEMA standard;
C850.3: For mechanical use (from fine cloth), with better mechanical performance than electrical performance, like the L series laminated sheet in NEMA standard;
C850.4: For both mechanical and electrical use (from fine cloth), with great electrical performance, like the LE series sheet in NEMA standard;

3025: For mechanical use (from coarse cloth), featured by excellent mechanical performance, high strength and slightly poor electrical property;
3026: For mechanical use (from fine cloth), providing superior mechanical performance. It is recommended to make small size parts;
3027: For both mechanical and electrical use (from coarse cloth), with higher electrical performance;
3028: For both mechanical and electrical use (from fine cloth), with high electrical insulation performance. It is recommended to make small size parts;
3025B: An economical phenolic cotton cloth laminated sheet for mechanical use (from coarse cloth), with good mechanical performance but bad electrical performance;
3025CS: Wear resistant material, ideal for making wear parts, without insulation purpose
