<P>PROBLEM TO BE SOLVED: To provide a paper that has excellent heat resistance, chemical resistance, and hydrolysis resistant performance, and also has both of insulation performance and cushioning property, and especially suitable for an insulating material for electrical equipment, a cushioning material and a buffer material. <P>SOLUTION: Provided is a paper comprising a PPS fiber. The paper includes a PPS fiber in an amount of 50 mass% or more, the number-average fiber length of the fibers constituting the paper is in the range of 1-4 mm, and the apparent density of the paper is in the range of 0.6-1.2 g/cm<SP POS="POST">3</SP>. The method for producing the paper includes subjecting an undrawn PPS fiber having a melt flow rate of 150 g/10 min or more and a fiber length of 5 mm or more to a dispersion in water and to a beating treatment for making the average fiber length of the PPS undrawn yarn in a range of 0.3-3 mm, and then to papermaking. <P>COPYRIGHT: (C)2012,JPO&INPIT |
