Hollow polymeric each containing a thermoplastic shell encapsulating the liquid hydrocarbon, The expanded microspheres are white, can be 15 to 90 micrometers in average diameter, When heated to a high temperature, the increased pressure of the hydrocarbon will cause the microsphere to expand,
Its use reduces weight, obtains products with smooth surfaces, and Ultra-low density when expanded
It is used in the manufacture of sports shoes, slippers and some auto parts
