5.sample:free
6.relative product:the other nonmetalic mineral product include vermiculite,mica,color sand.
7.process:High white light calcium carbonate selects high purity limestone as rawmaterial,then
grind use machinery.It is pure and stable filler whose bulk density is small.
8.we are the special nonmetalic mineral product manufacture,and look forward keep business
relation with you.we can promise the best quality , service , timely shipment .
9.payment:T/T or L/C
10.packing:25kg/bag or as your need.
