Application

1.As a filler in the plastic industry, hollow perlite cenosphere, wood-plastic products (wood substitutes, imitation wood) and other products have the advantages of large dosage, low cost, high strength, good heat resistance, and low thermal conductivity;2.Make good lightweight refractory materials so that they have the characteristics of high strength, long life, and small high-temperature thermal conductivity;3.Produce high-efficiency thermal insulation materials at low prices;4.Make waterproof coatings with good functions;5.It can achieve better leakage plugging effect in cementing exploration technology;6.In the metallurgical industry, it is used as a filling material for casting and welding car partitions, and as a material for sand cores;7.Mixing an appropriate amount of microsphere into vinyl plastics can make effective muffler equipment, reducing the noise from 95 to 100dB to below 90dB, and can also be used in muffler coatings, etc.;8.Utilize the high strength and wear resistance of hollow microspheres to make automobile brake pads, friction pads, oil drilling rig brake pads and other products, which have the characteristics of good physical properties, long service life and low production cost.
