1-3mm, 3-5mm perlite refractory

1-3mm,3-5mm expanded perlite   Product Description   Expanded Perlite is an economical insulation for high and low temperature and cryogenic applications.it comes when the raw perlite(perlite ore) is heated to a suitable point in its softening range,it expands from volcanic lava.It is widely used because of its low thermal conductivity, cost, non-combustibility and low moisture retention.   PHYSICAL PROPERTIES
