MICA PAPER
Three kinds of mica paper
are muscovite good in quality of Sichuan for supply of which one kind
is made by thermal chemical treatment and another by hydraulic separation
process.The mica is first reduced to pulp and then made into the form
of paper either in rolls or in sheets.
According to its different
manufacturing process,our mica paper is classified into three types
viz:501-2,506 and 507
