METHOD FOR PRODUCING SOFT SHEET

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing a soft sheet, especially a method for producing the soft sheet wherein a rolling process is shortened. SOLUTION: A mixture which is a raw material of the soft sheet and a die having a cross-sectional hole through which a molten mixture passes are prepared. The method for producing the soft sheet has: an extrusion process for making the mixture pass through the cross-sectional hole of the die to mold a long object; a cutting process for cutting the long object molded in the extrusion process to obtain a predetermined cut object; and a rolling process for rolling the predetermined cut object obtained in the cutting process to mold the sheet of a uniform property. A material of the mixture is a composition obtained by compounding a fluororesin with an inorganic filler and a cross-sectional shape of the long object molded in the extrusion process is annular.
