Poly- tetrafluoroethylene fibrous powder body, poly- tetrafluoroethylene paper making ones, production method of poly- tetrafluoroethylene compact, and poly- tetrafluoroethylene fibrous powder body

摘要

It is the poly- tetrafluoroethylene fibrous powder body where peak area ratio of the low temperature side in the melted endothermic curved line which is obtained at the time of differential scan type calorimeter analyzing which per minute you can do at programming rate of the 5C, is 88.5% or more of all the peak area. In addition, they are paper making ones which consist of the said poly- tetrafluoroethylene fibrous powder body, are superior in balanced pressure characteristic, permeability and dust collection characteristic.
