Crude perlite market size for sandblasting accounted for more than 40% of the total industry share in 2016. It is majorly applicable in sandblasting industry, owing to its low density and uneven rough shape which makes it an important component in sandblasting machines and helps in providing efficient surface levelling, abrasion & polishing effect for various industrial equipment. The product exhibits brilliant abrasive properties with high heat resistivity and low density which makes it desirable for several industrial applications like sandblasting, sand casting, filtration, industrial polishing etc. Rapidly growing construction industry in Asia Pacific, which is attributed to industrialization and urbanization in the region will subsequently drive product demand and therefore, will have positive impact on the unexpanded perlite market size in the near future.
Crude perlite market size for casting sand and mixtures is projected to witness gains of more than 3.5% in the coming years. Product is mixed with sand casting mixtures as cushioning agent to recompense for the expanded crystalline silica when it goes through phase change with more than 1000°F heat. It also reduces its cleaning room costs by minimizing the casting defects for instance, veining, buckles, penetration and fissuring. Moreover, it improves the penetrability of the sands that decreases its venting defects. Thus, growth in metal & steel industries along with substantial product applications in foundries will drive product demand, which will make notable contribution to unexpanded perlite market size in the coming years.
Asia Pacific unexpanded perlite market size is likely to witness gains of more than 4% over the forecast timespan. The regional growth is mainly driven by the extensive product application in sandblasting, casting sand mixtures and foundries. Rising foundry applications including sand casting and slag coagulant in the region is mainly attributed to the increasing construction and industrial operations which is likely to trigger mining activities to attain more perlite for its application across aforementioned industries. For instance, China discovered over 15 mines in their country in 2008, which doubled the perlite production and expansion and is likely to help boost the crude perlite use across various applications including slag coagulant, sandblasting, casting sand & mixtures, etc. which will subsequently have positive impact on the crude perlite market size in the coming years.
