Nylon scale board is toughness angular translucent or milk white crystalline resin, as engineering plastics, its molecular weight average of 1.5-30000. Nylon has high mechanical strength, high softening point, heat resistance, low friction coefficient, wear resistance, self-lubrication, shock resistance and sound absorption, oil resistant, resistant to alkali and solvents, good electrical insulation, self-extinguishing, non-toxic, good weather resistance. Its affinity with glass fiber is very good.
